@OP
I don't think that's noobs question.
I asked one month ago still no one answered but there's a way, these are binaries and are compiled from source and we need to edit source before compiling.
But I want a solution to reverse engineer them.

it's hard to edit already compiled binaries and i don't think there is any softwear to edit this already compiled binaries but it's too easy to edit when he was not compiled mean in source.

Yep it is but I tried opening them using hex editor and much stuff of it was visible but not complete.
I don't think its impossible to reverse engineer binaries.
I believe someone will come up like brut who made apk reverse engineering possible.

YUP hex editor IS NOT FULL WORK WITH THIS AND FOR reverse engineer binaries NEED SOMEONE MASTER

Has anyone figured this out yet? Since these are usually small executables I could start reverse engenieerig them but im sure someone already has all the source code on some online repository?
Has anyone who posted above found an easy solution?
boy do i wish the world was full of nice honest hard workers who all made things open and didnt steal..... theres a tiny bug in android 4.3 roms and my guess is its on purpose lol... if i can edit just a few lines of code i can fix so much :/

4k thanks and disabled? Yikes id probably take your side lol. Some binaries are incredibly easy, or were you referring to these ive done this before but the process depends upon their compilation methods and can get very nasty
Edit: oh darn... He cant answer huh? Woulda been another thnx

ummm whenever I need to open a .bin file I use 7zip you able to extraxt the contents from inside the .bin file

Are these files the same as .so files?

I have a file that is a bootloader.bin, however the 7z doesnt work

well smali files corresponding to those java will be there and the edits will need to be for smali not java directly..
and as i see the changes in commit it may not be easy task to do as i don't know anyone here in SGA has enough smali coding knowledge to make that much of changes

[Q] What is VRTHEME??

I saw lots of theme which has this in their title. but I can't find any guide or tutorial about this. So, what is this? how could I use it? has it any benefit over usual "decompile/theme/recompile/replace"ing an apk?Is there any script to implement it like apktool?
Its the universal theme flasher created by Villain ROM.
As for all your other questions I'm not sure.
Sent from my GT-I9100 using XDA
thanks,
correct me if I'm worng pls.
Universal theme flasher, is kind of template. and I should extract compiled PNGs and xmls from apk file and paste theme into that. and for editing theme, I need to paste and replace those files into the apk file and then decompile that apk.
then what should I do if I changed something in "values" folder? cause it just appears in decompiled apps and It can't be seen in a compiled app.

I think after compiling the apk, you should copy the "classes" and the other file *-) I can remember its name, and add them there.
Am not sure *-) I had this question too but I thought abt trying it first and if it doesnt work I wld ask. I have no time to try I have exams

classes.dex is for the smali that has been edited if there was any.
I assume that if the xmls were edited and they point to new PNG images/objects then the resources has been changed. I would say that in this case you would need to have an updated resources file for these adjustments? This could be pulled from your newly compiled .apk that you want to base your flashable theme off?
I am unsure if resources needs to be updated though for certain? I have flashed in the past new xmls and they worked fine, however these were not referencing any new sources or images...so my thoughts are that these mods I made didn't require this additional file?? I could be wrong. I really should read the thread about it here on XDA. I did a long time ago, but have come a long way since then.
I diverse. Try using it without new resources file and see what happens?
You may also like to looking into Morphing as well (very similar concept).

i would also like a explanation to what vrtheme is, all i know is that when i flash it IT NEVER WORKS!

Xmls are usually in simple english with tags like html(though it has no relation with html.I wanted to mean for eg like <preference> </preference> ) if you read the lines you can understand I guess

The visual portion in Eclipse is for layout xml files. If your xml is just a plain xml it will not do anything for you visually.
What exactly are you trying do?
Use Google to find tutorials about xml file creation. A simple defined search such as "android xml tutorial" returns quite a bit of info.

Well im trying to build a systemui. And i know i can pnly build it from scratch.
But the trouble im facing is i cant even start a project related to what i want to do..
I read and search for tutorials beyond tutorials but still cant find anything anout opening a window to do that.
Just some tutorials stating that what relative layout and linear layouts and some about how to add features related.
Havent looked into videos though. Because what i saw at the first page of google was about how to install adt plugin.
So the main problem im facing now is, could anyone give me some tips or guides to open a window to start my next phase of learning
I hereby support an OFF-Topic thread.

I'm going to assume, probably a bad idea (lol), that you mean for a sony device as that is what is in your signature. Why not pull apart an existing systmeui from that device and go through it to see what stuff is doing? Then you can create what you want.
Here is a link for a tutorial about a Sense device but the basic idea is similar for all devices just the procedure might be a little different. http://forum.xda-developers.com/showthread.php?t=1453869
Also, in this forum are threads on decompiling the systemui.apk.

[Q] Edit .apk wirh winRAR possible?

Hey guys,
I was searching for a tool to edit an apk file and i found Apk Tool on xda but i think it's not
that much easy to work with this program. (for a n00b, like me.. )
I managed to open and edit te file with winRAR,
but is this program also capable of proper compiling the app again, ready to use?
I tried it and it worked well i think, but is this possible with any app or other kinds of changes?
If this is stupid or something, please tell me. I am not very experienced in these kinds of things.. (neither in english, sorry.. )
Somebody any ideas?
Thanks in advance!

It all depends on what you edit,obviously you didnt make a fatal change,so it must have been small,no its not possible to edit anything else as far as the manifest and xml files.You'll get a parsing error.

Okay, that's true i only changed those kinds of files and it wasn't a problem yet.
I changed somethings in an demo version of an app and now it recognizes it as the full version so winRAR can be pretty usefull for apk edit if you keep things simple like this..

[Q] Help Required Editting framework.jar

Hi, I am hoping that one of the Android developers on here might be able to give me a bit of advice please regarding editting my 'framework.jar' file.
I have a Jiayu G3 phone running Android Jelly Bean 4.1.2 but my caller ID is not functioning properly because it is not matching local & international numbers. Having done a lot of searching it appears that this is probably due to the parameters in the 'framework.jar' file as per this post on xdadevelopers here
I have succesfully decompiled the 'framework-res.apk' file using apktools and confirmed that the 'config_use_strict_phone_number_comparation' variable is set to false. However, I am having trouble decompiling the 'framework.jar' file.
I have copied the 'framework.jar' file from my phone and opened it in a Jave decompiler. However, all I am presented with is the following:
Code:
META-INF
MANIFEST.MF
preloaded-classes
(See attached image)
In the xda post it says the following:
II) Check for and fix MIN_MATCH constant in telephony framework
1) Decompile framework.jar
2) Open smali/android/telephony/PhoneNumberUtils.smali
3) Search for MIN_MATCH constant and set it to 0x7
Click to expand...
Click to collapse
...but I don't appear to have that in mine.
Am I doing something wrong.
If anyone could offer any advice I would be very grateful.
Many thanks
Russell
P'S. I tried replying about this in the original xda post itself but I don't have authorisation to post in the developers section so I thought I would try here instead.
So, is no one able to help me with this then. All the searching I've done indicates that when I decompress 'framework.jar' then I should have 'classes.dex' inside. However I don't have that.
Can anyone explain to me why this is please before I pull the rest of my hair out.
Thanks

You have to use apktool and apply the command to decompile..
eg.
apktool d framework.jar
this in cmd, will create a new folder named framework.jar.out, then you navigate inside this folder were all the smali's files are etc..
PS. you can't open framework.jar in java decompile, you can open framework.jar extract the classes.dex then use dex2jar tool and turn it back into framework_classes.jar this is the one that can be viewed with java decompilers
Does annybody know....
Where i can find a clean Settings.apk for the GE 4.3 (i9505) that i can mod? (Decompile/Recompile)

Ok, I'm gradually learning here. Having done a bit of research it appears that my rom is odexed (I have .apk and .odex files in my /system/app folder).
I'm assuming then that this will scupper my plans to edit my framework.jar file.

No no, you just need to deodex your ROM then, luckily for you I've got a little thread here - [Info/How-To/Tools] Deodexing Made Easy... - which will help you with that, obviously ignore the Xperia Z Users part and give the rest a read.
