Wifi Calling, Modifying, & Signing ims-service.apk - Android Q&A, Help & Troubleshooting

​ims-service.apk is part of Wifi Calling. Upon decompilation it appears to contain a file res/values/strings.xml that contains information for connecting to the tmobile sip server. Now, I would like to modify this server info so I can connect to the sip server of my choice. However, merely decomp/editing/building ims-service.apk creates an unusable apk. This is due to its lack of signing? Would I be able to sign the apk myself or would I need the cert the authors used due to trust issues from other apk's using this apk (rendering any rebuilds futile and signing impossible)? Another approach I found would be to just decompile, edit the xml, and add the xml into the unmodified ims-service.apk. However, upon openning ims-service.apk with 7zip there is no res/values/ folder or the strings.xml.
Any guidance?

looks like all i have to do is drag in a modified resources.arsc?

[RESOURCES] - Theming the Atrix 4G: tools, processes, locations, etc.

I know that there are a good number of Atrix users who are new to android, new to theming with android, or like me - both. It can take hours to find the right information to make the changes that you want to make, only to find out that those types of changes are phone specific and that guide that you finally found after hours of searching doesn't even apply. I ask that all Atrix themers contribute to this thread with their knowledge, processes, and best practices for theming the Atrix. This way, we can share knowledge amongst each other as well as set up some accurate guide for other Atrix themers just getting started.

Setting the notification dropdown shade to transparent
I'll start off with a post that I made yesterday in response to someone's question about apk Manager.
1. apk Manager Atrix Guide
The file I am going to discuss here is /system/framework/framework-res.apk. This file contains most of the elements involved in theming your phone. There are many other smaller locations to edit, but this file contains the bulk.
Before we get started on using apk Manager, we should understand a few things about framework-res apk. This file consists of a few important elements:
regular png image files - these are standard png images and can be edited with your image editing program and saved without any problems.
draw-9 png image files - these are special types of png images denoted by a .9.png in the filename. The android system reads these filenames and recognizes the image as a stretchable image. The system knows how to stretch the image based on a 1px wide border that the image has. This border contains black dots/lines along each of the four edges that tell the system how to stretch it - if you mess with this border then the way the image stretches will changes and you may not be able to decompile/recompile the apk. The following link provides info on editing draw-9s, but I found it easiest to extract them with apk Manager, edit in gimp without touching the border, and then recompiling with apk M. More info on draw-9 pngs
xml files - these files are in binary code in the framework-res.apk. The apk needs to be decompiled in order to return these to human readable code. Also, many of your xml files are hidden within the resources.arsc file in the framework-res.apk and cannot be accessed unless you decompile.
In order to make any changes to the xml files or the draw-9 pngs within framework-res.apk you need to decompile it rather than extract it. Extracting the framework-res.apk with a program like winzip simply unzips the file and does not break the code back down to an editable format. Decompiling the framework-res.apk with a program like apk Manager will actually break down the resources.arsc file into the sepereate xmls folders (values, etc.) and also restore the instructions border to draw-9 pngs.
Draw-9 images not edited correctly will not stretch properly in the system and may cause decompilation/recompilation errors. XML files not edited correctly may also cause recompilation errors. It is very important to pay attention to the log.txt file for any errors that may be occurring during your decompilation/recompilation process.
Download apk Manager
Now here is what I've learned about apk Manager:
put framework-res.apk in the place-apk-here-for-modding folder
run the script
enter 22 to select an apk, then 1 to select your apk
press 9 to decompile the apk
go into the projects/framework-res.apk/res/drawable-hdpi folder and edit your pngs or xmls (maintain the border)
go back to the script once your done editing and enter 11 to compile
when asked if it is a system apk enter y
when asked if you want to extract other files too enter y Do not skip this step, apk Manager will seem to produce a working framework-res.apk if you skip this step but when I did it soft bricked my phone
go into the keep folder that was created and delete any pngs that you changed in the projects folder
if you change any xml files, you will also need to delete the resources.arsc file from the keep folder (this is because mane of the xml files are compiled into this resources.arsc, so to tell apk manager to rebuild it with the new xml, we need to delete the original)
go back to the script and press any key to continue
your recompiled framework-res will be in the place-apk-here-for-modding as unsigned-framework-res.apk
extract unsigned-framework-res.apk using winzip, or similar program (this is being it is compressed incorrectly)
go into the folder where you just unzipped the framework and zip it up with the compression mode set to Store - call it framework-res.apk
you are ready to go with a properly editing framework-res.apk, put it on your phone any way you like
Make sure that you have no errors when de-compiling or re-compiling. It might seem like everything is going ok, but you could end up soft bricking your phone if you don't check the log.txt in the apk Manager main folder. Check the log.txt after every decompile and recompile to ensure that you don't have a damaged framework-res.apk.
The output in log.txt should like like this for a proper decompile:
Code:

The system cannot find the file specified.
If you get any errors about your images or xml then you need to fix them before you can recompile.
#framework-assistant2. Framework-res.apk Assistant
Here is a tool which I use regularly to pull the current framework-res.apk from my phone, as well as to push any updated framework-res.apk to my phone. To use this batch program you need to:
Download the View attachment 584667
Extract the zip to whereever you want the program to reside
To pull your current framework-res.apk - run the Framework-Assistant.bat and tell it to pull
To push an updated framework-res.apk - place the updated framework-res.apk in the bin/push folder, run the Framework-Assistant.bat and tell it to push the updated framework-res.apk
It is always a good idea to tell it to back up the current before pushing a new
As with any and all framework-res.apk pushes, this has the ability to soft brick your phone depending on the framework-res.apk you push, or anything else for that matter. Use at your own risk.
Here are my steps to edit framework-res.apk from start to finish which might help those unfamiliar with the process:
Run Framework-Assistant.bat and answer y to pull the current framework-res.apk from the phone, but n to push the latest version (this will simply retrieve the current framework-res.apk from your phone)
Copy that framework-res.apk from the Framework Assistant/bin/pull fodler into the place-apk-here-for-modding folder of apk Manager
rename framework-res.apk to something distinguishable, I add the current time (ex: framework-res-1016.apk). Trust me, things can get messy if you end up making a few passes with different edits, you need to keep your stuff straight.
Run Script.bat in the apk Manager folder, 22 to select which apk to use, then 9 to decompile
Go into the projects/framework-res-1016.apk folder and make any changes you wish. Most png changes will be in drawable-hdpi, xmls are pimarily located in the values and layout folders.
Once I've finished making updates, run Script.bat again, 22 to select the proper apk, then compile with 11 - follow all compilation steps above all the way through zipping it as store.
Place the new framework-res.apk in the Framework Assistant/bin/push folder and run Framework-Assistant.bat
Choose y to both pull and push the framework-res.apk (I find its always a good idea to pull your latest working framework-res.apk from the phone before dropping a new one in)
If you anticipate more edits, go back to apk Manager and paste the new framework-res.apk in the place-apk-here-for-modding fodler of apk Manager and rename it with the current time attached (ex: framework-res-1023.apk)
Delete the unsignedframework-res-1016.apk and the unsignedframework-res.apk fodler (just to keep things clean)
You now have an edited framework-res.apk on your phone and are set to fix this little issues you missed on this pass, just run the apk Manager Script.bat again, enter 22 to access your latest framework-res.apk (framework-res-1023.apk) and repeat the process.
#framework-assistant3. Editing OR removing the status bar clock in services.jar
You will need:
Some zip program, I use winrar
JDK - Java Development Kit Get the JDK
baksmali to decompile and recompile the classes.dex file - View attachment baksmali.zip
Notepad++ free editor for code editing (I recommend this program for any/all code editing, apart from hex)
Here is how to change the status bar clock color:
Install the JDK
Extract baksmali to your computer
Retrieve services.jar from the /system/framework folder
Extract services.jar using your zip program (right click on the file and choose to extract)
One of the extracted files is classes.dex, copy it into the baksmali folder
Run decompile.bat in the baksmali folder - this will decompile classes.dex and place the contents in a new folder called classout
Navigate to classout\com\android\server\status
The next step involves changing clock color:
open StatusBarIcon.smali with Notepadd++ and find this entry
Code:
.line 61
const v6, -0x1
invoke-virtual {v4, v6}, Landroid/widget/TextView;->setTextColor(I)V
const v6, -0x1 identifies the color of the status bar clock. I changed this value to "const v6, -0xff000000 to set my clock to black. Essentially the last 6 digits of this entry will determine the color of the clock. Set the last six to any html color code (google it) to set your clock color. I have only tried black here as it is all I needed, so I can't personally guarantee that anything else will work.
The next step involves removing the clock:
open StatusBarPolicy.smali with Notepadd++ and find this entry
Code:
invoke-direct {p0}, Lcom/android/server/status/StatusBarPolicy;->updateClock()V
It should be under ".line 592", now add this line underneath the line just mentioned:
Code:
invoke-virtual {p2, v3, v6}, Lcom/android/server/status/StatusBarService;->setIconVisibility(Landroid/os/IBinder;Z)V
Once your done editing, save the file
Navigate back to the baksmali folder and run recompile.bat - this will rename the original classes.dex file to orig-classes.dex, and the recompiled file is saved as classes.dex
Zip up the new classes.dex along with the META-INF folder that was extracted from services.jar as, you guessed it, services.jar Leave the compression setting on Normal
Put services.jar back in your system/framework folder
This is all that I know how to do with servies.jar right now, if anyone has some additional good info please post it to this thread and I will add it on.
Can't believe I forgot to thank all those who have contributed both directly and indirectly to my knowledge thus far: Nottach, NyugenHuu, KennethPenn, riral, tonecreationz, gera4eva, HFHimself, and many random threads I found on the wonderful xda forums.
1. Setting the notification dropdown shade to transparent
Instructions:
Download Baksmali Tool - directions for use are at the end of post 1
Open the services.jar file for example with winzip, 7z, winRar, or whatever. Unzip the classes.dex file into the folder with decompile.bat and recompile.bat from the Baksmali Tool zip.
Run decompile.bat - this will decompile classes.dex into a new folder called classout folder. Browse to classout/com/android/server/status and open the file called StatusBarService.smali with a text editor like notepad.
Search for "const/4 v5, 0x2", it should be under ".line 1629". Just change this to "const/4 v5, -0x3" and save the file.
Run recompile.bat - this will recompile the classout folder into classes.dex and rename the original file to orig-classes.dex
Open again the services.jar file with any zip tool and overwrite the classes.dex file with the one just created.
Now search the drawable-hdpi/status_bar_background.png file in the framework-res.apk and make it transparent.
Push the updated framework-res.apk and services.jar back to the /system/framework/ directory on your phone.

the resources file was never rebuilt after it gets recompiled after I delete it from the keep folder. does yours?
Yes, if your resources.arsc is not being rebuilt then it means that you have errors in your process. Post the contents of your log.txt here.

There is a ton of errors. I think reason could be because of the way the original framework was built? i am using gingerblur as a base. Here is my log: http://conceptvisionz.net/uploader/images/log.txt
After I delete the files from the keep folder, they're never replaced w/ my new files when the apk is compiled. What happened??

statusbar_background and title_bar_portrait are not proper draw-9 pngs. You will need to fix these before you can recompile. This error will keep apk Manager from using anything in your projects folder when it compiles.
Here are valid pngs for those two images. If you are unable to fix yours, try replacing your with these in the projects/framework-res.apk/res/drawable-hdpi folder and then try to compile again.

Check your log.txt, chances are that there are some draw-9 pngs that are causing apk Manager to fail its processes. Post the log here if you would like me to look at it.

Thanks, I am still experimenting with it. I manage to recompile fine now. Reading logs really does help. I manage to get my menu to show the color I want. Now just need to work on the secondary menu when when you press more. It is tricky because the main menu popup you can use standard color codes #ff808080 is the gray I used and works fine. But for the secondary menu you cant use color codes, it fails compilation.
EDIT: so i finally got it to work (the secondary menu) but adding in textColor and remove text appearance item.
So for main popup bottom menu, this is the field to edit: TextAppearance.Widget.IconMenu.Item, change the textColor directly to a color of your choice in this format #ffffffff (white), mines is #ff808080 (dark gray).
For the secondary menu for areas that has a "more", find this field: Theme.ExpandedMenu, and just add in a textColor entry. You can copy and paste the one from TextAppearance.Widget.IconMenu.Item. remove the text appearance item.
3 days work finally solved, thanks everyone. Now the theme is a bit more flush with certain third party apps.

i got it, look at my posted, i edited above.
I've been able to track down most of the colors that I want to adjust in the xml files, however I cannot seem to find where the corporate email is getting its color from. The image below shows the white text that I can't find out how to change. Had anyone been able to locate the source for this?
Also, does anyone know where to edit the clock in the status bar's color?

yeah it's in services.jar, http://forum.xda-developers.com/showthread.php?t=549309
Thanks Nguyen, I had actually decompiled the classes.dex from services.jar a little while back; but without a guide I had absolutely no idea what I was looking at. Its a bit more complicated than framework-res. Once I get in there and make the changes I'll add something about editing services.jar to the first post of this thread.
Look for the .line 61
The below changes it to green from white
Code:
.line 61
const v6, -0x1
to
.line 61
const v6, 0xFF4CFF00
0xFF4CFF00 - wouldn't a straight white be 0xFFFFFFFF?
I'm coming from an html background and through all the xml edits I've done and whatnot, the white color code is FFFFFFFF. So, to go to black my code should be 0xFF000000, right?
**edit, actually I just threw that second code you posted, 4CFF00, into gimp and it gave me a bright green. Maybe you meant the bloew code changes from white to green?

I worded it weird. Guess I shouldve said from white to green instead of to green from white.

yeah that would be white all Fs. The first two FFs control alpha, while the ohter 6 are just like html hex colors.
I got in there today and blacked out my clock, thank you both for the help. I've also added the steps and some useful tools to the first post for editing the status bar clock.
I'm so damn close to having my phone the way I want, for this week at least, but I've run into a new snag and don't know where to look yet. I edited the following code in styles.xml:
<item name="windowBackground">@drawable/screen_background_dark</item> under <style name="Theme">
and I changed it to @drawable/menu_bg, which referenced a background image I created and replaces the screen_background_dark which points to the black color in the drawables.xml file. For the most part this works perfectly, as seen here:
The only problem is, and this really is the only one I've found, is my alarm settings screen:
If I change that one value back to black then the alarms screen show up perfectly fine, black background, white alarm text, etc. I'm not ever sure where to start to look for the solution to this one. Maybe I should just sleep:

[Q]Problem after changing AndroidManifest.xml

Hello Guys and Galls,
I want to change the background of Settings.apk from black to white. I use the FroyoMod Rom http://forum.xda-developers.com/showthread.php?t=815595.
If change
Code:
<application android:label="@string/settings_label" android:icon="@drawable/ic_launcher_settings" android:taskAffinity="">
to
Code:
<application android:theme=[COLOR="Red"]"@android:style/Theme.Light.NoTitleBar"[/COLOR] android:label="@string/settings_label" android:icon="@drawable/ic_launcher_settings" android:taskAffinity="">
in AndroidManifest.xml.
I use ApkManger to decompile and compile. The (de)compiling is without any errors.
After compile with ApkManager i do the follow:
- open original Settings.apk and unsignedSettings.apk with 7-zip
- delete AndrodManifest.xml in original Settings.apk
- copy AndroidManifest.xml from unsignedSettings.apk to original Settings.apk
- copy the modified original Settings.apk to the phone in /system/app
- chmod 644 Settings.apk
- chown root:root Settings.apk
So now if I start Settings nothing happens, nothing, not even an fc.
This is was logcat says:
Code:
com.android.settings has no certificates at entry AndroidManifest.xml
What I´m doing wrong?

i read this on the mobile and did not see that....
solving the problem? because I would be interested
Me too, I'm having a problem recompiling an AndroidManifest.xml with apkmanager 5.0.1., it won't install unless I use an original AndroidManifest.xml file first, then I can flash right over it. At first I thought it was a the change I made in the file, but I just decompiled and compiled an unmodified version, and it did the same thing. So its the compiler.
Settings.apk is a signed system app. It will refuse to run unless signed by the same key as the rest of the system apps. Just replacing a single XML in the APK will cause a signature mismatch.
Best bet? I'd say make your change, then use a kitchen like dsixda's to resign the whole system with the test key (I think this is a menu option).
Yep your whole system has to have the same signature. I did this edit for a rom a while back, but I made the settings transparent instead of white background by using Theme.Wallpaper.NoTitlebar. Just sign your whole rom together with testkeys and all should be good until another system app gets changed/modified and the signatures don't match again.

Thanks to Gene Poole and one_love_420, I will try your instructions.
If your after quickly signing a whole load of apk's, I wrote a command line front end to do all the hard work for you.
You can even generate your own private key.

After reading jacknb1ack's comment I felt compelled to re-write this whole thread to accommodate for the various PC Programs that you use to do all of your apk modding which can and do make things a hell of a lot quicker. I've wrote this as something I would have liked to have come across when I first joined because I know there is a lot to take in, and hearing you need to decompile, edit this or that xml, recompile, sign etc etc etc can be off putting for some especially if you struggle to get a program or apktool setup to begin with.
Knowing how to use command prompts will be beneficial in the long run so I've wrote a detailed guide below which covers it from start to finish along with how to Sign and Zipalign your apks, pulling them from the computer and so on. I've also covered some Theming basics with links to everything you're ever going to need, which will be extra handy if you're just getting started.
Minimum Requirements:
A Rooted Phone.
Java SE Runtime Environment
Java SE Development Kit
Any of the apk modifying methods below.
7-Zip or WinRar
Theming Requirements:
Notepad++
Photoshop, GIMP or any other image editing software.
Patience. :silly:
To avoid any java not found issues you need to set up the PATH for it in Environment Variables, you can find a short Guide on how to HERE. This is how mine looks...
Code:
[B]C:\Program Files (x86)\Java\jre6\bin;[/B]
I would advise that you also install the Android SDK but if you don't want to you can download this APK_Mod.zip that you can extract to a folder and place it anywhere you want on your Computer (I recommend C:\APK_Mod) and run any adb, apktool, zipalign or signing command prompts from it. You can find a more detailed guide for this method below.
But first off all here are some of the most common Programs that you can use to modify and theme your apks, and I'll start with one of the best...
Virtuous Ten Studio (VTS)
Virtuous Ten Studio (VTS) is the ultimate solution for the modification of android applications.
This program allows you to manage entire Android projects within an easy to use and familiar environment.
The intended group of users covers anyone from a themer over ROM devs up to the smali gods known for their awesome mods of existing apks.
The modifcation of smali code is one of the biggest features in VTS. You can easily decompile, edit and recompile any apk or jar file.
However, the application is not limited to smali files. You can edit almost any file found inside an apk or jar.
Virtuous Ten Studio is also the official successor to the highly important M10Tools released last year by the Virtuous Team.
You can easily edit any m10 file from Sense apps in order to resize or change them.
Additionally VTS brings support for un- and repacking of boot images (boot.img), a job that previously required a cygwin installation with the dsixda kitchen.
Since VTS' own implementation is a native windows solution, which means you don't need dsixda or cygwin anymore.
VTS has been designed to run on Windows, has been in development for nearly two years and has gone through many stages of testing.
Today VTS is a highly respected full blown Android IDE (Integrated Develoment Environment) suited for all your reverse engineering tasks.

Command Prompt Editing​
Basically this is just manually doing what all of the programs above need to do in order to decompile, recompile, sign and zipalign apks so it's worth knowing how to modify apks this way for occasions when the above programs for whatever reason gives you issues.
Use Linux or a Mac?
See the following threads for more information on using apktool on other Operating Systems...
APK Manager for Mac OS X
[Linux][UTILITY][TOOL] APK Multi-Tool
[tutorial] decompiling,recompiling and signing in linux (27-01-2013)
How to install and use Apktool with Ubuntu
Getting APKs To Your PC​
You have two options here...
1. Use a file manager on your Phone to copy and paste files to your SD, then connect to your PC and use Windows Explorer to copy and paste to your desired location.
2. ADB. Open a command prompt window in the ADB folder (see below) and type/copy the following command...
Code:
adb pull /system/app/ Original_apps
...which will pull the whole app folder to your computer and create a new folder called Original_apps, which you can then simply copy apps to the main folder ready to be modified (keep the Original_apps folder as a backup). Then do the same for your framework folder...
Code:
adb pull /system/framework/ Original_framework
...want to pull your Phones whole system...
Code:
adb pull /system/ Xperia_Z_System
...you can rename "Xperia_Z_System" to whatever you want.
Further Information: [WINDOWS][TUT]ADB tutorial, setting up ADB, usefull commands, collecting debug info.
This is a zip of the apktool folder I currently use - APK_Mod.zip - which as said above also contains the ADB files needed to pull and push apps from your Phone, or you can check out the following links...
[Tool] ADB Fileexplorer
[TOOL][WINDOWS] Android Apktool
Installing Resources​
For apktool to work you need to install the resources needed by your apks for de and recompiling, and those resources are other apks, the first apk regardless of your Phones manufacturer is going to be your framework-res.apk. The second apk you need is dependent on the manufacturer so you need to check your framework folder for another apk such as twframework.apk or SemcGenericUXpres.apk, in some cases it might even be the SystemUI.apk but you would need to check if you have issues with the other two. Put those two apks in the APK_Mod folder to begin with then open a command prompt window. The easiest way for me is holding the shift key then right clicking the mouse and selecting Open command window here, but if you're not able to do that then click your Start button and search for Command Prompt, then open it. You then need to point it to the relevant folder, so type cd then copy and paste the location of the folder (cd C:\APK_Mod) and hit enter.
The install commands are...
Code:
[B]apktool if[/B] framework-res.apk
...and for the second...
Code:
[B]apktool if[/B] SemcGenericUXpres.apk
Decompiling​
The command for decompiling is...
Code:
[B]apktool d[/B] framework-res.apk
...and so on for each individual apk you want to modify. A new folder will be created that is named after the apk you are modding, then you can edit xmls, smali files and .9png images. You'll notice that there are a lot more folders when you decompile an apk, that's normal as those folders are from the resources.arsc and where you'll find the xml files you may need to edit to make the changes you want.
Recompiling​
When you've done editing it's time to recompile, using the command...
Code:
[B]apktool b[/B] -insert folder name-
...and if you've edited your files correctly then it should compile with no errors and create a folder named dist in the decompiled folder along with a new apk.
Signing​
Before using the new apk you will need to sign it, to do this you need to extract (open the apk and simply drag and drop them to the dist folder) from the original apk the resources.arsc (only if you haven't changed anything in the values folder, the AndroidManifest.xml and META-INF folder (if it exists), then copy them into the new apk. In WinRar it will give you the option to choose the compression method, and it's vital that you choose Store as the compression method because if you don't then you WILL BOOT LOOP after restarting your Phone!
NOTE: If you have edited anything in the values folder then extract the resources.arsc from the new apk and copy (drag and drop) it back in the same manner described above.
Alternatively you can use the following command...
Code:
[B]java -jar signapk.jar testkey.x509.pem testkey.pk8[/B] framework-res.apk.apk framework-resS.apk
...notice the extra "S", the output name has to differ from the input name otherwise it will give an error, if done right it will create a new apk called framework-resS.apk, just remember to rename it back to the original before using it on your Phone.
Signing For The Play Store​
If you plan on Publishing a Theme or any other app/apk to the Play Store then using the above method to sign your apks just wont work because you need to give it an individual signature that is unique to you, thankfully @AndroidGraphix has written a great guide that will show you how, it's a bit more fidgety than the above method but simple enough to follow...

Zipaligning​
DISADVANTAGES OF UNALIGNED APKs
Quite understandably, situation would be reserved for unaligned application packages. Resource reading would be slow and memory usage would be on the higher end of the spectrum. It would also depend on how many unaligned applications are present. For example, if less number of applications with an unaligned home application, you’d see slower application launch times. This is the best case scenario. For a worst case scenario, having a number of unaligned applications will result in the system repeatedly starting and killing processes, struggling with lags and huge battery drain.
Click to expand...
Click to collapse
- SOURCE
The command for zipaligning is...
Code:
[B]zipalign -v 4[/B] framework-res.apk ZAframework-res.apk
...notice the "ZA", again that can be anything you want so long as it differs from the original name, I use ZA for an obvious reason, and again don't forget to rename it before using on your Phone.
Getting apks back to your Phone​
It's just a reversal of how you got them off your Phone to begin with, use a file explorer and put your apk on your SD Card, then move it to the Phones System folder and change it's permissions to rw-rw-r, then move and replace it with the original. Most apps should continue to work but if you change your framework-res or SystemUI you will most likely need to reboot. Or you can use adb to push and install them. Check the previous link for the commands.
If all the above has worked correctly you should now have your modified apk installed with the changes you've made displayed on your Phone.
Theming & Modifying​
This is where the fun begins, once you've got setup to decompile your apks then obviously you're going to want to mod them, so here's a few pointers to clear up what seems like a daunting process to new comers...
To start with you'll probably just want to start with replacing images, so if that's all you want to do for now then here's a quick tip, you DON'T need to decompile or sign your apks!, simply edit and rename your replacment images on you computer, preferably using the same or similar dimensions then drag and drop them back into the right folders in the apk, always using Store as the compression method, but PLEASE NOTE; .9 pngs can be replaced in the same way, but if you want to edit them in Photoshop for example then you need DO need to decompile them.
A few things to note...
Smali code is real Developer territory, it's Matrix code to me , thankfully there's usually a guide to follow so you can simply copy and paste code without having to fully understand how it works, so don't fret about this.
.9pngs are simply png images with a 1 pixel border. You can edit anything within that border but anything on or over will give errors when building. Unless you're creating an image from scratch then you can leave the border as it is, it's that simple! Sure there's a bit more to .9png editing but you can find a few links below that go into more detail about .9s and how they work.
xmls are relatively simple and edited with Notepad++, much simpler to understand than smali and again, there's usually a guide to be found for most mods you may want to make yourself, but if you're feeling brave you can experiment with it when you have a basic understanding of how it works.
Restoring modified files if you mess up is easier and quicker with a CWM.zip, especially if you're modifying any framework apks! Just because an apk might build with no errors doesn't mean it won't give you any when installed to the Phone.
.9png Editing​
I hope after reading this explanation you're left wondering what all the fuss is about, as it really is quite simple. I'll use the following two images, btn_default_pressed_holo.9 & status_bar_close_off.9 to illustrate the basic point of the borders...
Decompiled .9pngs:
Recompiled .9pngs:
Those borders control which part of the image is stretched, and we'll use Draw 9-patch which is for editing the borders of decompiled .9pngs and lets you see how the image, when stretched, will be displayed on the Phone. Notice that the borders are different sizes, well that's because I only want/need a certain part of the image to stretch to get the desired look on the Phone.
...in the image below the left side shows the stretched image and desired effect should look on the Phone and the right side shows how it would look if I had edited the borders incorrectly or used none at all...
You can get away by not using a border but you would need to edit your image to specific dimensions to accommodate for the stretching, for example it might look fine for a simple OK button but it might not look right if you used the same .9png for a screen press which stretches the whole length of the screen, so you're better off just using them to begin with, plus you'll more than likely get errors down the line while decompiling or recompiling your apk.
The use of the border is made even more clear when you add text to an image. For my status_bar_close_off.9 I've filled all four sides of the image (except for an empty pixel in all four corners as that is the max amount of border you can use) as I need it to stretch the image just how I've edited it...
...but if I used the same sized left side border as the btn_default_pressed_holo.9 then this is how it would look on the Phone...
...which is obviously not the look I'm trying to achieve, as the left side border is causing the image to stretch incorrectly.
So that's basically it, depending on the image you're editing you can usually leave the borders alone but if you create one from scratch then you might need to play about with them if your images doesn't look quite right when used on the Phone. Here's a few links that will assist you further, especially the batch editing...

Xposed Framework​
rovo89 said:
In this thread, I'm presenting a framework which gives you the possibility to modify your ROM - without modifying any APK (developers) or flashing (users)!
...
Advantages:
No need to modify any APKs. This means:
No need to decompile, change things in smali, compile, sign, ...
It will work for odexed and deodexed ROMs.
Your mod is not bound to a specific version of the ROM. Unless there is a major change in the methods called for a certain functionality, your mod will continue to work even when you upgrade your ROM. Hell, it will probably even work with different ROMs.
Multiple mods can be installed at the same time, even if they change the same package. So you can use these battery icons and those quick toggles. Even hooking the same method twice is possible. Of course, this only works properly if the mods are not trying to do incompatible things.
It does its magic at runtime. That means you can implement options to let the user decide if they prefer the bikeshed to be painted in red or blue. Or you can have some extra logic for certain ROMs without building different mod versions.
It can be disabled easily without having to reflash.
It's open source.

Flashable Clockwork Mod (CWM) zip​
ClockworkMod Recovery zips are used for flashing individual files to whole ROMS and can be a life saver if you push a badly edited apk to your Phone that results in a bootloop. There's also a few programs that can assist you with that too, but if all you're doing is replacing a few files all you really need is a template, then it's just a matter of creating the Phones folder setup in the zip which is simply creating folders: system\app - system\media\audio etc then dragging and dropping your files into it. A basic understanding of the updater script is essential, a ROM.zip will more than likely wipe your Phone whereas a Theme.zip may just replace files but it might delete some also.
See below for a CWM.zip Template but first some helpful links...

This is my Theme_CMW_Template.zip which is set up so you can add your own files to the framework and apps folders in the main system location, but you can easily add other folders to it if you want to add things like fonts, tones or anything else, just remember to add folders within folders if that's where the files you want to include are such as tones, media\audio\alarms for example.
If you navigate to META-INF\com\google\android you will find the updater-script which controls how the zip works and the text you see when you run it in CWM. As this zip is just for basically over writing files you don't need to edit anything except for a few lines...
...this is how I've edited it for my Ice Green ResMods theme...
...so just edit it using Notepad++ to your liking.
When adding files to your zip add them using Normal as the Compression Method...
...and that's pretty much it. Remember to remove the text files I've added otherwise they will be flashed to your folders too.
Deodexing​
The first thing I do when installing the latest firmware is Deodex it, mainly because having a deodexed ROM is easier to modify and you'll find a lot of the modifications that are are in the Themes And Apps sections require you to have a deodexed ROM. I use the dsixda's Android Kitchen to deodex and @pankaj88 has written a great guide here - [GUIDE] How to DEODEX stock ODEXED ROM using dsixda's kitchen - so you can do it yourself, or you can give the following tools a try.

The differences between Odex and Deodex Files...
In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space The odexed file structure works well as an optimization tool. Since these .odex files contain preliminary load information about each system app, the OS knows what to expect when it’s booting up, and consequently, loads all these apps faster.
On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.
For instance, on a non-rooted device you’ll find
system/app/Phone.apk ===> as well as ===> system/app/Phone.odex

[Q] Editing Android Kernel - HCE/NFC

I'm currently in the process of creating a custom version of AOSP that will edit the functionality of the Host-Card Emulation feature of Android, allowing me to manually set the AID produced when my device goes into emulation mode.
I've downloaded the Android source, and have located the files I think governs HCE functionality.
From the NFC System Service, I've located the following files:
"CardEmulationManager.java" and "HostEmulationManager.java" located in "/aosp/packages/apps/Nfc/src/com/android/nfc/cardemulation/"
And from the Android core framework, for the NFC API I have found:
"CardEmulation.java" located at "/frameworks/base/core/java/android/nfc/cardemulation/CardEmulation.java"
From here, i'm unsure how to get started in editing the code. I'm unsure of the interactions between the files, and how they are called at run (I.e. which functions in the file I should be looking at, how would I go about adding my own code/modifying existing code in the file)
Is there any documentation online about how these files work/are ran? Or how would I go about finding out on my own (Through debugger tools etc.)
I'm currently using Eclipse for Ubuntu, and will be developing for a Nexus 7

How to Re-Sign System APK for Android

I wanted to disable the Flash to black/screen update function on my yotaphone 2 e-ink's screen as it really disturbes me. I worked out there was a setting to do this in the phones SDK app.
I decompiled the YD_YotaphoneSDK.apk app and changed some of the settings in the classes.dex files so as to disable the full screen refresh (i.e change the backscreenmanager waveform mode to A2). I then recompiled the YD_YotaphoneSDK.apk app however when I attempt to install it on my YotaPhone it states 'Parse Error- There was a problem while parsing the package'.
Im pretty sure it needs to be resigned but cannot workout how, when i attempt to do so in android studio i get the following error: Error:Android Source Generator: [YD_YotaphoneSDK] Package is not specified in AndroidManifest.xml
Can anybody with some relevant experience give my some suggestions of how I can resign or enable this recompiled version of the APK to be installed on my yotaphone.
I have attached the edited apk file
Regards
