hello everyone
I have updated to kennethpenn's 4.5.91 Gingerbread Beta 4 (must say, it is truly a phenomally put together build !)
I have also noticed that many of the mods that i had applied to 1.8.3 have not been updated for 4.5.91, so i decided to make the changes myself.
Now, I have a pretty decent knowledge of Unix-based operating systems ( I have used Red Hat Linux, Ubuntu, SUSe Linux, OpenBSD, FreeBSD, Solaris, and now OS X) however, I would like to expand my knowledge to include Android.
The first one I attempted to do myself was the Wake on Volume Keys mod.
This is a very simple change to the android.policy.jar file, as you all well know.
For this, I used Windows XP, simply for the fact that I have 7zip and PeaZip installed on it. However, I can do all of this on OS X as well. The file archiver applications I have on OS X are:
1. The Unarchiver
2. Keka
I am going to list my method of applying this edit, and i would ask that someone with solid knowledge on this subject give me their feedback and guidance.
---------------------------------------------------------
My Method of editing android.policy.jar
---------------------------------------------------------
1. Using Root Explorer, I made a copy of /system/framework on my External SD Card
2. Mounting the Phone for USB Mass Storage on Windows XP that I have running in VirtualBox on my Macbook Pro, I moved the copy of the /system/framework directory to my Desktop
3. I downloaded smali-1.2.6.jar and baksmali-1.2.6.jar from code.google.com/p/smali/
4. I placed both of these .jar files in the copy of the framework-edited directory that I created on my Desktop
5. I renamed smali-1.2.6.jar to smali.jar and baksmali-1.2.6.jar to baksmali.jar for simplicity's sake
6. I moved the android.policy.jar file to /framework-edited directory on my Desktop
7. Using 7zip (I also have PeaZip, but for this, I used 7zip, if you think I should use PeaZip, please tell me) I extracted the files from android.policy.jar to end up with classes.dex and META-INF. I then moved classes.dex to /framework-edited so it is in the same directory as smali.jar and baksmali.jar
8. In Command Prompt, I entered:
Code:
cd C:\Documents and Settings\Owner\Desktop\framework-edited
in order to be working from the proper location where my files are located
9. Now, having Command Prompt working in the proper location, I entered the following commands:
Code:
java -jar baksmali.jar -o classout/ classes.dex
to create a new directory within /framework-edited called /framework-edited/classout
10. I then opened the /classout directory, and navigated to /classout/com/android/internal/policy/impl/ and opened the file KeyguardViewMediator.smali with Notepad
11. I used [Ctrl] + [F] to locate the line:
private isWakeKeyWhenKeyguardShowing(I)Z
12. I then looked at the lines DIRECTLY below the above line, and following the Original Post on how to manually apply this modification, I removed lines:
0x18
0x19
13. Upon removing these lines, I simply did a File -> Save As -> KeyguardViewMediator.smali and saved the file to my desktop
14. I [Cut] + [Pasted] the edited KeyguardViewMediator.smali file back to /classout/com/android/internal/policy/impl/ and replaced the original KeyguardViewMediator.smali file
15. With the edited KeyguardViewMediator.smali file in place, I went back to Command Prompt and entered the following commands:
Code:
java -Xmx512M -jar smali.jar classout/ -o new-classes.dex
To create a new file called new-classes.dex
16. Changing the name of new-classes.dex to classes.dex, I took the original META-INF file, and my newly created classes.dex files, and, using 7zip, created a new android.policy.zip archive
17. I renamed my newly created android.policy.zip to android.policy.jar, and transferred it to my External SD Card
18. Using Root Explorer, I navigated to /system/framework on my phone, and renamed android.policy.jar to 1122android.policy.jar.bac and [Copy] + [Pasted] my edited android.policy.jar to /system/framework
19. I then immediately powered off my phone, and rebooted into CWM Recovery, and cleared my Dalvik Cache, then rebooted the phone normally through CWM Recovery.
At this point, to my knowledge, I had successfully edited my android.policy.jar file and had manually added the Wake on Volume Keys modification, however, once the phone was fully booted and showing my lockscreen, I unlocked the phone as normal by sliding the slider to the right. As soon as the phone unlocked, I saw pop-ups for processes that had failed and were terminated. I'm not sure what the exact message the pop-ups had, but it was the normal pop-up message you get when a process force-closes. My only option was to click "Ok" so I clicked it, only to have another force-close pop-up.
Apparently, every single process on the phone had force-closed, BUT, the phone was waking when I press a volume key while the screen was off. I had no choice but to pull the battery out.
I decided to reboot into CWM Recovery and "install .zip from SD Card", Nottach's 1% Battery Mod / No Carrier Mod Uninstall Script
I installed Nottach's uninstall script because I hoped that it had an unmodified copy of android.policy.zip in it.
After installing the uninstall script, and rebooting the phone once again, I got to the lock screen, unlocked the phone, and found everything to be in perfect working order, just as before I edited anything,
But the Wake on Volume Keys mod was still applied!
So now, my questions / requests to all of you are:
1. Explain to me what I missed or did wrong that resulted in the force-closure of every single process on the phone prior to installing Nottach's Uninstall script
and
2. Educate me on the proper process that you developers use to apply small modifications such as this one to the android.policy.jar file, or any other related file on the phone for that matter.
My plan is now to change the color of the text on my lock screen (Clock, Date, and possibly Carrier) following this [Guide]
Any and all feedback is welcomed and greatly appreciated, as you will be helping me learn the beginnings of modding and developing

I am trying to modify a few APKs in an updated ROM I just installed. I was able to modify these in a previous release but now I am having trouble with SystemUI.apk. The SystemUI.apk in the ROM has no META-INF. How does this work?
If I modify and replace, I loose my status bar. If I copy the original from the ROM back, my status bar does not return. The only way to get my status bar back is to restore from a full backup.
Any help in how to modify this, or just understand how it is working in the first place would be appreciated.
What are you using to decompile the apks? Are you getting any error messages when you try to recompile it?
Apktool 1.4.5174001. No errors or warnings on decompile. No errors and one translation warning on compile.
Have you placed the right 1.apk and 2.apk in your C:\Documents and Settings\"your user name"\apktools
Yup framework-res and twframework-res from this ROM. Even though it looks like its only using 1.apk.
Update:
It's not the decompiling tools at all. I tried copying the unmodified SystemUI.apk back to /system/app, verified ownership and permissions. When I rebooted the phone, the same thing happened. No notification bar.
IDK sorry try pulling a systemui from a stock updated rom and past all you modified on that one. Sorry I could not help more Ill try to work on mine when I get home see if I can figure anything else for you.
I got it to work, sort of. I took the ROM and placed my SystemUI.apk inside, then flashed. I'm still curious about this SystemUI not being signed but still working as long as its not replaced.
Update:
After I found that the above worked, I create my own update.zip with just the SystemUI.apk inside. This also worked! Is there some reason that it did? The only difference I can tell is that the file access and modify time stamps are set to 2008
Code:
[email protected]:/ $ stat /system/app/SystemUI.apk
stat /system/app/SystemUI.apk
File: /system/app/SystemUI.apk

Change: 2012-05-26 23:27:02.000000000
I'm glad it worked out for you.
Hi! I have a very odd problem: somehow my SystemUI.apk mods won't keep (i.e. after pushing, the XML edits are reversed to stock). I'm attempting to remove the brightness slider. It should be a simple edit to the tw_status_bar_expanded.xml: add the red code; many others have used this edit successfully (Verizon GS3, international GS3, etc.):
Code:
<LinearLayout android:orientation="vertical" android:id="@id/brightness_controller" [B][COLOR="Red"]android:visibility="gone"[/COLOR][/B] android:background="#ff000000" android:layout_width="fill_parent" android:layout_height="56.0dip">
However, it didn't work on my phone, even after three attempts. So, on a hunch, I edited something totally different:
Code:
android:background="ff000000"
to
Code:
android:background="00000000"
-- which should make the brightness bar transparent: that didn't work after pushing, either! Frustrated, I pulled the SystemUI.apk back and saw that...somehow...the XML had "reverted" back to stock, showing
Code:
[B]android:background="ff000000"[/B]
Here's my "flow," if anyone can diagnose this wacky issue:
1. Use Virtual Ten Studios (an IDE, integrated development environment) to pull SystemUI.apk (after installing framework-res.apk resources).
2. Create backup of SystemUI.apk
3. Edit XML in SystemUI.apk -> save -> recompile and zipalign.
4. Copy AndroidManifest.xml and META-INF folder from backup apk to modded apk.
5. Boot phone into recovery -> push modded SystemUI.apk to /system/app [states that it pushed correctly] (I do recovery because, as I just learned, you can't push to a phone that's on, if it has a secure kernel; adb remount or adb shell mount still yield permission denied, but recovery doesn't!).
6. Reboot.
I thought it was just a fluke, but I ran the experiment again, this time changing the color of the bar: ff000000 -> ff000001 (left is XML before pushing; right is XML after pulling): http://prntscr.com/qoqcx
Thought it could be a permissions issue, but I ran adb shell -> chmod 644 /system/app/SystemUI.apk from recovery. Still doesn't work! I pulled the just-modded pushed APK and, boom, there it lies with none of my edits. :/
Any thoughts out there?
There's got to be a reason... My phone can't be a demon. Right?
For what it's worth, I've successfully flashed a SystemUI.apk as a flashable zip, so my phone isn't immune. There's just something wrong with my process....

hi Everyone,
I'm sticked with the common issue of how to make writable the external SD.
I've read topics on the forum:
http://forum.xda-developers.com/desire-601/help/how-to-writable-external-sd-kitkat-t2877686
http://forum.xda-developers.com/desire-601/help/sd-card-permissions-off-t2833195
http://forum.xda-developers.com/showthread.php?t=2687734
Well ok, but I'm a noob so sometimes it's not clear, sometimes it's not working for me.
So let's explain:
- My device is rooted (it was made by a tech using TWRP if I'm right)
- SuperSU is installed
1/ I tried some apps like SDfix and Int-SDCard Write fix
> Result = KO
2/ I tried to manually modify the platform.xml file > sometimes the editor does not want to save the modification, sometimes it says OK but the file don't seem to be modified (the last modification date is still 2014). Permissions are: rw-r--r--
a. Using Rom Toolbox, I go the file and edit it with:
-FX TextEdit > Get a Warning = "This file is on read-only filesystem. You will not be able to save any changes unless you first remount it as read/write'
> Result = KO
- RB Text Editor: it seems i can edit it. Save the file without warning message 'Saved'. But once back on the /system/etc/permissions folder, nothing looks modified (not today's date). I can reopen the file and see the modification by the way. But once I reboot, I go back the my original issue.
> Result = KO
- ES Text editor: can't even save the file
> Result = KO
So what ?
I've seen this message coming along:
"if you are rooted then you doing something wrong (did you maybe forgot to mount system as R/W ?).
If you are unable to do modify platform.xml then you doing something wrong or yours device isnt rooted."
> At what moment is it possible to mount the system with R/W grants ?
I'm fed up with not being able to write on SD card....................
Thx in advance !!!!!
Opening a terminal on my phone:
- i can't 'cp file1.xml file2.xml' in /system/etc/permissions
- i can't 'chmod 644 file1.xml'
Each I get "Read-only file system"

I am trying to install a clean Android System WebView (packagename: com.android.webview) onto stock LG G5 RS988 RS98821d Android 7.0 that is rooted.
I downloaded an arm64 WebView APK from the Bromite Releases GitHub page:
https://github.com/bromite/bromite/releases
I tried installing the Bromite WebView APK to "/system/app/webview/" (0644 permissions) and rebooted, but the WebView implementation could not be used.
There are instructions regarding installing Bromite System WebView available:
https://github.com/bromite/bromite/wiki/Installing-SystemWebView
From my reading of the installation instructions, "res/xml/config_webview_packages.xml" from "/system/framework/framework-res.apk" must contain the an entry for the package with the particular package name ("com.android.webview" in this case).
After examining the stock "config_webview_packages.xml" member file, it appears that a reference to "com.android.webview" is not present. The "config_webview_packages.xml" XML file also appears to not be easily readable in a text editor. My guess is that it has some kind of signing.
What must be done to get the system to allow the newly installed WebView? My impression is that the "config_webview_packages.xml" XML file must be edited, but it is not clear how to do so, given that it does not appear to be just plain text.
I have attached a copy of the "config_webview_packages.xml" XML member file and the original framework-res.apk file zipped into a ZIP 2.0 archive.
XML files inside apks are compressed, you should unpack the framework-res.apk using a tool for apk editing, not just a zip archiver program. On Android, you can use APK Editor Pro, for example.
By the way, have you already uninstalled Chrome? If Chrome is installed, it will be forced as the standard WebView provider.

It was my impression that the APK files were zip files with a particular signature block. I shall try a tool like APK Editor Pro and report back.

I have uninstalled/removed both Chrome and the Android System WebView (Google Apps version).

Now I'm on PC and I remember the name of the tool I use sometimes on PC: APKChanger. It's very complete, although very heavy (about 650MB with my current configuration);
If you have platform tools installed on your pc, or the whole Android Studio, you can also use
Code:
aapt d xmltree framework-res.apk res/xml/config_webview_packages.xml
to see the list of allowed webview packages.

So we can be sure the problem is not the system forcing Chrome as default WebView provider. So, as Bromite's wiki states, "Changing the package name does not make installation easier/possible;", so the only solution is to add com.android.webview to config_webview_packages.xml, or, if it is already there, remove the requirement for Google's signature on the webview package. EDIT: I checked, on your file com.android.webview is missing, you just need to add it:

On Android, I used APK Editor Pro 1.10.0 to modify res/xml/config_webview_packages.xml of /system/framework/framework-res.apk. A new APK with a generic signature was generated with the modification. I used the XML file editing option to select and modify the config_webview_packages.xml. The XML file editing functionality is given to be in beta and appears buggy.
I replaced the original /system/framework/framework-res.apk file with the patched one using the TWRP 3.2.3-0 file manager and attempted to boot to system. The system would start, but get stuck at the LG logo screen. I tried wiping data, and cache in recovery and booting again, but received the same result. I note that adb was available and usable after the boot process got stuck on the LG Logo screen.
My impression is that the patched framework-res.apk file is incompatible or defective. Perhaps APK Editor Pro 1.10.0 malformed the output APK (the XML editing feature appeared unfinished) or that the LG stock ROM expects framework-res.apk to have have a particular signature.
Perhaps a different APK editing tool should be tried. What could the problem be?
I have attached a ZIP archive containing the APK Editor Pro 1.10.0 modified framework-res.apk.
EDIT: Attachment has been removed; the file was defective and should not be used. Attachment is no longer necessary.
I have now patched framewor-res.apk successfully, and Bromite System WebView is working.
Did you use again APk Editor Pro or a PC tool?
The tools I used were Windows tools (and with a Java dependency in the case of Apktool) and were: Apktool 2.3.1 and WinRAR 5.6.1. I found that it is best to avoid newer versions of the tool unless trying to manipulate Android 9 Pie or newer resources.

From somewhere else it seems that you are now using Apktool 2.3.1.
After comparing my notes, my impression on what you are missing and some related notes:
The modified framework-res.apk should use the unmodified APK file's "AndroidManifest.xml" root file and META-INF directory contents. It is not sufficient for any of the content to be the same after decompiling.
Copy "AndroidManifest.xml" and META-INF directory from original framework-res.apk to modified framework-res.apk using zip program, if contents are different.
v2 APK signing scheme (which includes the APK file itself in validation), if present, would be broken, but the scheme's enforcement is not enforced on /system; v1 APK signing scheme (on APK contents ("AndroidManifest.xml" file and META-INF directory contents)) is still enforced.
I zipaligned output/modified framework-res.apk prior to transferring original "AndroidManifest.xml" file and META-INF directory contents, but I do not believe it matters for the purposes of getting a functional framework-res.apk.
EDIT: Some added things to keep in mind:
Sometimes clearing system cache and the runtimes cache is also necessary before system will boot after framework-res.apk replacement. Also make sure that the permissions of the replaced framework-res.apk file are at minimum whatever the original file permissions were. Depending on what software you use to replace the framework-res.apk file, the permissions set may be different.
I really appreciate the help, still does not work unfortunately.
Here is what I do:
adb pull framework-res.apk
apktool d framework-res.apk (tried most versions, mainly now 2.3.1)
Edit framework-res/res/xml/config-webview-packages.xml to:
Code:
<webviewproviders>
<webviewprovider description="Bromite WebView" packageName="com.android.webview" availableByDefault="true" isFallback="true" />
</webviewproviders>
Removing other dev versions with signatures etc
apktool b framework-res
zipalign -v 4 framework-res.apk framework-res-new.apk
Move META-INF and AndroidManifest.xml from the 1st original framework-res.apk > framework-res-new.apk (Have also tried moving res & resources from the new to the original...7Zip, WinRAR, CLI - Linux)
adb push framework-res-new.apk /system/framwork-res.apk
Modify permissions in TWRP > 0644
Move framework-res.apk from /system/ to /system/framework/framwork-res.apk (I read somewhere this is better than pushing directly. Neither worked)
Clear Davlik & Cache
Reboot
Hangs on boot screen
Any ideas if I am missing something important?
@burny02 - Please clarify whether the framework-res.apk you are trying to modify is for LG G5 stock ROM Android Nougat.
I note that you are using the "isFallback="true"" flag with the webviewprovider tag. The purpose of the isFallback attribute set to true (its default is false) is to specify that the WebView provider should be disabled by deault and should only become available when allow other WebView providers are disabled. Using the attribute with the true value with only a single WebView provider seems improper. I do not know if boot should fail if the attribute is present in the way that it is, but in both scenarios I would recommend its omission.
It has also been a while since I used Apktool versions and do not exactly remember the command lines. Do not take my not pointing to an issue with it as there necessarily not being an issue. One thing I would mention is that one typically first install a frameworks before decompiling and building. For the LG G5 RS988 Android Nougat, I believe installing the framework-res.apk as a framework was sufficient. You would specify on command line "apktool if framework-res.apk" and any tags you wish to explicitly specify, if any.
The moving of framework-res.apk to /system/ before /system/framework/ is oftentimes done by people to try to install a modified framework-res.apk with proper permissions and on a live system before the system crashes and reboots. Once framework-res.apk is copied to /system , but does not replace the framework-res.apk file, proper permissions can be set prior to using that file to replace the live framework-res.apk. It is still important to note that some software disregards permissions set when a file is relocated or copied, so this could be an issue if framework-res.apk is replaced with more restrictive permissions than the original framework-res.apk (less restrictive permissions should not usually be a problem for the app to be used). I particularity do not like the idea of the system crashing and prefer to make such changes offline (such as via the aid of a custom recovery).
Sorted. Got it working. Really appreciate the help, Ascii3
For anyone looking at this in the future, the isFallback back seems to stop booting, regardless of whether it is the only entry or not.
The procedure then works as above:
adb pull framework-res.apk
apktool d framework-res.apk (2.3.4 worked for me - SDK 24 Android 7.1 (LGG5))
Edit framework-res/res/xml/config-webview-packages.xml to:
Code:
<webviewproviders>
<webviewprovider description="Bromite WebView" packageName="com.android.webview" availableByDefault="true" />
</webviewproviders>
apktool b framework-res
Move META-INF and AndroidManifest.xml from the 1st original framework-res.apk > new framework-res-new.apk (Used 7Zip drag & drop)
adb push framework-res-new.apk /system/framework/framwork-res.apk
Modify permissions in TWRP > 0644
Clear Davlik & Cache
Reboot
I found the following unnecessary :
Installing framework (apktool if)
Zip-aligning
Moving to /system prior to /system/framework/ (Using TWRP, live system; it might be necessary)

The isFallback attribute is supposed to only be set to true for no more than one webviewprovider. Explicitly setting it to false (its default) should not be problematic (but does result in a larger config-webview-packages.xml file generated). Setting isFallback to true on the only webviewprovider item is not an intended use and apparently results in no boot.

I do not think zip-aligning apps is necessary generally . My understanding around the reason to do so is to try to optimize the packaged data to be more efficiently fetched in the manner which Android fetches the data.

Hello guys, sorry to exhume this post but I'm struggling and all other threads are maybe ten years old...
So I'm struggling to replicate what you did! I'm no expert but I can follow basic instructions.
So I do as you say, decompile framework-res.apk, modify the xml file (I just add the line). This step seems okay since I did some errors while editing the file and apktool would not recompile properly. Now this goes fine.
Then I got my freshly recompiled framework-res.apk, but 7zip on linux won't let me insert META-INF and AndroidManifest.xml. So I had to rename the extension .zip, do it, then rename in apk. Could this be an issue? It looks dirty.
Anyway, after this you didn't had to resign the apk? I read everywhere you had to, so I did. I did not zipaligned it since I used a resign tool I found on xda and I could not tell if I had to do it before or after resigning, but since you said you didn't zipalign it I thought whatever.
The problem is the following: after replacing framework-res.apk in /system/framework, the phone won't start, I get stuck on the starting screen and I could extract the following from logging:
01-24 04:15:17.470 +0000 4042 4042 I PackageManager: /system/framework/framework-res.apk changed; collecting certs
01-24 04:15:17.749 +0000 4042 4042 W PackageManager: Failed to scan /system/framework/framework-res.apk: Failed to collect certificates from /system/framework/framework-res.apk
Have you got any ideas of what I did wrong? It's my fourth soft-brick today, I'm getting a bit annoyed.
Thanks in advance
@LeSplendide did you ever get this working? Not sure if I'm having the same trouble, but I followed burny's instructions and my phone fails to boot. I checked logcat but I don't see anything relating to framework-res. I'm using magisk to overlay it because if I touch the /system partition for real, VoLTE stops working on my phone (known issue for this phone). I'm successfully overlaying stuff in /system/app and /system/priv-app so I do have overlaying generally working, though this is the first apk in the framework directory I've tried to overlay. Boy do I want to get this working. I've extensively degoogled and debloated this phone and the only glaring thing that remains is chrome handling webview.

I'm sorry I have no idea, rn Webview Implementation says I have Android System Webvew 102.0.5005 so I assume this is chrome webview? But I have no clue what I did or not but I know for sure I fixed my problem which was that Webview would crash when trying to sign in a google account on my MicroG'd LEAOS. Now this works so I guess I did make it work. All I found that could be a clue is a update.zip containing instructions and the webview in question. Iirc, the issue was that the zip needed to be signed so that twrp could flash it, so I think I just signed my zip and it worked but can"t tell for sure.
