Всем привет. Меня зовут Алексей и я занимаюсь реверсом adnroid-приложений. Многие, кто делал реверс android-приложений, сталкивались с тем, что при обратной сборке с помощью apktool приложение не собиралось и писало об ошибках во время Building resources. Как правило эти ошибки можно исправить вручную в местах их возникновения. Но что делать когда их много? На исправления уйдет не один час. Сегодня я расскажу как бороться с эти за пару минут.

1. Устанавливаем на устройствоэмулятор где будем использовать приложение lucky patcher и патчим устройство.

Toolbox → Patch to Android → и патчим первые 2 пункта как на картинке.

2. Собираем приложение с помощью apktool. Apk не создастся, но если у вас не будет ошибок в smali файлах, то у нас будет собранный .dex файл по адресу папка_приложения → build → apk

3. Открываем с помощью winrar оригинальный apk и кладем туда наш модифицированный dex-файл.

4. Устанавливаем на пропатченное устройствоэмулятор. Profit.

P.S. Однажды я столкнулся с приложением, которое генерировало токен на основе подписи apk. И именно такой способ помог мне выяснить это и удачно начать генерировать токены в своем боте)

I am experiencing very annoying problems with the application apktool problem.
I do not understand what i am doing wrong, or what the problem is.
I tried this on debian , and on linux mint. I used different versions of apktool,

resulting in the same error:

I: Checking whether sources has changed...
I: Checking whether resources has changed...
I: Building resources...

It seems it can not use aapt , but i read about apktool.
And it seems that aapt is build inside apktool , why is it not working ?

Well, there
are many reasons why but I will show you most common errors. Note, i’m talking
about general apk modding, not system apk/framework modding

Assets.dex issue «Class xxx has already been
interned» and «Not a valid dex magic value»

By default,
apktool try to decompile dex from assets folder which would decompile to
smali_assets on a root directory of decompiled apk, and compiled to assets.dex
upon compiling

This can
cause compiling issues

Solution:

To fix the
problem, decompile APK again with the flag [code]—only-main-classes[/code] to
only decompile on main classes in root (classes[0-9].dex) then you can compile
without any problem

Note:
Only for apktool 2.4.1 and up

You can try
to delete .dex from assets folder or smali_assets/assets.dex but it may cause
problems

If you are
using APK Easy Tool 1.57 and above, you can enable the option «Only
disassemble the main dex classes» under Options -> Apktool. Again, only
for apktool 2.4.1 and up

Error: No resource identifier found for attribute
‘manageSpace’ in package ‘android’

The attribute
does not exist in the framework or it could be fake attribute to prevent compiling

Solution:

Remove android:manageSpace=»true» from AndroidManifest.xml

Error: String types not allowed

Issue: https://github.com/iBotPeaches/Apktool/issues/2462

Solution:

In this case:

This error
tells you which xml an error occured and which line

Open the XML file: E:(PathToDecompiledAPK)resvaluesdrawables.xml

Remove drawable name=»APKTOOL_DUMMY_1c2″ />  at line 5 and save the file

You will get another
error about public symbol. See below

Error: Public symbol XXX declared here is not defined.

Public symbol
does not exist in public.xml

Solution:

In this case:

W: E:(PathToDecompiledAPK)resvaluespublic.xml:1133: error: Public
symbol drawable/APKTOOL_DUMMY_1c2 declared here is not defined.

Open the XML
file: (PathToDecompiledAPK)resvaluespublic.xml

Remove <public type=»drawable»
name=»APKTOOL_DUMMY_1c2″ id=»0x7f0601c2″ /> at
line 1133 and save the file

Resource error (APKTOOL_DUMMY) (Split APK)

If you get
APKTOOL_DUMMY that’s generally because apktool can’t decode some of the
information in the original APK and creates a ‘dummy’ value instead. Because
there’s no things called APKTOOL_DUMMY in public.xml, the APK can’t be
recompiled. It’s likely because you try to compile splitted APK with some
missing infomation

Solution:

Merge split
APKs manually

https://platinmods.com/threads/how-to-turn-a-split-apk-into-a-normal-non-split-apk.76683

Or use the
SAP (Split APK Packer) tool

Other issues

— APK is
protected, encrypted or obfuscated. Reversing of such files is beyond the
scope, so find out yourself

— Invalid syntax
in smali and xml. You may have done something wrong

You can
search for useful infomation on the following sites.
