hi all,

I was putting this guide together for one of our staff members as we are automating our builds soon and I needed to compile a proper list of the effected files and folders.

Here is a good summary of all the editing I do each week:


PRE-CHECK

1. Always make sure to run: apktool if framework-res.apk before running the decompile command
2. apk files and source files MUST NOT be in the same folder
3. When rebuilding the apks from the source file folder the source is created in: Source/build/apk/

From there we need to get:

resources.arsc and in some cases the classes.dex

APKS requiring the classes.dex are:

MiuiMusic/build/apk/classes.dex
Mms/build/apk/classes.dex

For other apks just the resources.arsc is needed and also in some cases the drawable-en-hdpi folder, layout-en, xml-en and one file from xml (will list these below)

If you are using linux you can do the following:

1. mkdir device_rom (Where device = nexusone for example)
2. Copy the following apks from system/app in your unzipped deodex

AccountAndSyncSettings.apk (Account manager for sync contacts, pictures e.g. Google (Gmail))
Backup.apk (MIUI Backup utility including Cloud backup and automatic backup)
Contacts.apk (MIUI Contacts app)
ContactsProvider.apk (Provider for Contacts, background app)
CloudService.apk (MIUI User account management apk)
DownloadProviderUi.apk (Used for Download management UI)
FileExplorer.apk (MIUI File manager)
Gallery.apk (MIUI Gallery app)
Launcher2.apk (MIUI Launcher)
MiuiCamera.apk (MIUI Camera)
MiuiMusic.apk (MIUI Music player)
Mms.apk (MIUI SMS / MMS app)
Monitor.apk (System application monitoring and firewall app)
Notes.apk (MIUI / Xiaomi notes app)
Phone.apk (MIUI Phone app)
Settings.apk (Common system settings)
SettingsProvider.apk (Background provider for settings app)
SideKick.apk (Search app in MIUI for global searching)
Superuser.apk (MIUI Customised superuser for application permissions management)
SoundRecorder.apk (MIUI Sound recording app)
SystemUI.apk (System user interface for status bar and toggle interactions etc)
TelephonyProvider.apk (Used for number lookup in framework etc)
TelocationProvider.apk (Used for GPS tracking)
ThemeManager.apk (mtz Theme manager from MIUI)
Torch.apk (Do not package with i9000 roms! no support for this apk) (CM Torch app customised by MIUI)

From system/framework you will need to get:

framework-res.apk (System framework)

Once you have all of these files in device_rom/ you can proceed to the next step.

Decompiling apks

On Linux and OSX you can issue the following command once you have ensured to run: apktool if framework-res.apk from within the device_rom folder:

Code:
for apk in *; do apktool d $apk; echo Decompiled $apk; done
(Note: Running apktool if framework-res.apk is essential for each and ever weekly build as it ensures the correct dependants of the system framework are available as part of the decompile and compile processes)

To recompile apks you simply need to switch the command to the following:

Code:
for apk in *; do apktool b $apk; echo Decompiled $apk; done
Summary:

apktool d = decompile command switch
apktool b = compile command switch

The above for commands are loops which run like any 'for' operator in programming so they make the task so much easier.

You can then see from running the apktool b command option that you have not got a 'build' and 'dist' folder within the unpacked apk folder e.g device_rom/Backup/build device_rom/Backup/dist

What you need to do is grab the compiled files from the Apkname folder (where apk name is = Backup for example) e.g. Backup/build/apk folder. This folder contains all the compiled files, drawables, xmls and classes.dex (Smali).

I'll add more to this later.

Cheers,

Mark
