Декомпилировать apk на windows

As a programmer, we frequently come across interesting apps and games on the Play Store. And we wish that there would be some magical software that can take the .apk file and reveal its actual source code.

So today, I’m gonna give you an ultimate list of the best APK decompilers. You just need to provide the .apk file and they will generate the complete project including Java source code and assets.

I have organized these APK decompilers into four sections.

• Open Source APK Decompilers
• Online APK Decompilers
• APK Decompiler for Windows, Mac, or Linux
• APK Decompiler Android/iOS Apps

Let’s have a look at each of them and select the best option according to your requirements.

Open Source APK Decompilers

JADX – Dex to Java decompiler

JADX is a reverse engineering tool that converts Dex and Apk files into Java source code. It can also decompile Dalvik bytecode to Java classes with ease. You just need to provide the Dex, APK, zip, aar, or aab file.

One of its main features includes decoding the AndroidManifest.xml file and other resources from resources.arsc

It is also packed with a built-in deobfuscator.

JADX comes with a command-line interface as well as an intuitive GUI. You can even use it as a library in your Java projects.

In JADX GUI, you can view the decompiled code with highlighted syntax, jump to the declaration, find usage, and perform a full-text search. Its GUI also includes the smali debugger.

All major Operating Systems such as Windows, macOS, and Arch Linux support JADX.

Pros

• Convenient and quick
• More perfect GUI interface, with more practical functions
• Decompile code readability is high

Cons

• Resource files partially missing

Apktool

Apktool is used for reverse engineering closed, binary, 3rd party Android apps. You can use it to decode resources to nearly original form. After that, rebuild them by making some modifications.

Apktool enables us to debug smali code step by step. It also creates a project-like file structure as well as automates some repetitive tasks like building apk, etc. which makes working with the app easier.

According to its developer, Apktool is NOT intended for non-legal uses or piracy. It could be used for adding support for custom platforms or some other features, localizing, and other GOOD purposes.

It is highly recommended to use this tool according to the fair use doctrine. But, the source code of Apktool is released under the Apache-2.0 license which means that you can use or re-distribute it however you like.

Pros

• Complete resource files
• Source code in detail

Cons

• Using more complex, need for a combination of multiple tools
• Cannot better view the APK architecture logic

APK Decompiler

This project makes it easy to convert an installed Android app that was built with the Android SDK into readable source files.

How to use

• Ensure you have ADB installed
• Attach your Android device
• Run dist/decompile.bat

That’s it! The output will be a zip file of the passed-in package or keyword that contains as much of the decompiled code as possible.

NOTE: There will be no .java files, but .class files will be generated. I’d recommend using something like JD-Gui (https://github.com/java-decompiler/jd-gui/releases) to convert it into Java code.

Some of the dependent projects are not able to parse all APKs, so it isn’t guaranteed to be complete decompilation. If you see any problems during the run of APK Decompiler, I would encourage you to file a bug report with the appropriate project author!

APK Decompiler wraps the following projects:

• dex2jar (https://bitbucket.org/pxb1988/dex2jar) – Generates Java .class files
• apktool (https://ibotpeaches.github.io/Apktool/) – Generates readable resource files

Download

apk-decompiler

apk CSigner

Along with signing apks, apk CSigner is capable of compiling & decompiling apks serving the purpose of pure sources/resources replacement.

Introduction: The developer recently joined Android Developers and has published CoolesTech RSS Feed Reader. All went fine until he had to self-sign his app (personal private key), and that’s what was like a nightmare (although it’s relatively easy); test keys worked like a charm when self-certificates failed… But Google does not allow test certificates as you may have noticed.

He tried signar 1.3 and signer 0.3 but after his app seemed successfully signed he still got “application not installed”.

So he created his own tool, called “CSigner” that only runs in windows and comes with 2 versions (32-bit & 64-bit)

The only requirements are Java and Windows.

APK Decompiler by Unbox APK

The UnboxAPK de-compiler is one of the best tools for uncovering the contents of an APK file and understanding how an APK allows the application to operate correctly. To decompile any APK file, all you have to do is upload your APK file to the platform above, where it says ‘Upload’. The de-compiler will take care of the rest, and start unraveling the contents of the APK file. Depending on the size and the contents inside the APK file, the time required to complete the de-compilation process varies. If the size of the APK file is small, the de-compilation process will take only a few seconds. The maximum size limit (at the moment) for the de-compiler is 100 MB.

Once the APK has been de-compiled, you can download the zipped file containing the de-compiled files through the UnboxAPK API. There are various ways to view the de-compiled files, and one of the best ways is to use Android Studio.

Currently, the UnboxAPK website only supports de-compiling Android applications. The capability to de-compile iOS applications will soon follow. The UnboxAPK decompile is powered by jadx.

Короткий практический пример как разобрать apk приложение, что-то в нем изменить и собрать обратно в среде windows без использования android studio. Статья подойдет для новичков, сложного ничего не будет. Будем изменять (русифицировать) не полностью русифицированное приложение для видеокамеры ordro pro ep8.

На написание статьи подтолкнула другая статья на Хабр — habr.com/ru/articles/780694
Однако там описано, на мой взгляд, недостаточно подробно, новичкам будет тяжело. Кроме того, в приведенной статье использовались средства сборки-разборки под Linux, здесь будет windows-вариант.

В качестве цели для исследования будет выступать мобильное приложение в формате apk для камеры ordro pro ep8.

При эксплуатации это приложение демонстрирует вполне разумную локализацию, но в некоторых моментах все-таки «проглядывает оригинал» на иностранном языке:

Картинка с сайта: habr.com

Разбираем apk.

Самое простое, что можно сделать на старте — просто переименовать apk в zip и посмотреть на получившийся архив приложения:

Картинка с сайта: habr.com

Такой трюк позволяет сформировать общее представление о приложении, но не более. В своем содержимом файлы все равно будут иметь нечитаемый код:

Картинка с сайта: habr.com

Поэтому понадобится утилита apktool.
Устанавливать (инсталлировать) ее не нужно, только положить рядом с apk. Может также потребоваться java.
Проверить, установлена ли java можно так:

Картинка с сайта: habr.com

Далее команда apktool d com-ordro.apk полностью разберет приложение:

Картинка с сайта: habr.com

После этого можно наблюдать в том числе smali, о которых говорилось в уже упомянутой статье:

Файлов много, найти текст, который хотелось русифицировать, непросто. Поэтому пойдем по пути наименьшего сопротивления. Возьмем скриншот иероглифа из картинки приложения, переведем в текст и поищем этот текст по всем файлам в папках:

Как не сложно догадаться для каждого языка имеются соответствующие папки, в одной из которых и нашелся иероглиф. Нас интересует «папка для русского языка» (values-ru):

Картинка с сайта: habr.com

В файле находим частично непереведенные названия вкладок, кнопок и т.д. Изменяем текст на правильный:

Не лишним будет заглянуть в иные, рядом расположенные файлы:

Собираем обратно в apk.

После того, как все необходимые изменения внесены, можно приступить к сборке нового apk.
Сборка apk осуществляется также apktool командой apktool b com-ordro, где в качестве аргумента — папка с файлами, в которых происходили изменения.
Готовый файл apk будет в папке dist:

Однако, если данный файл перенести на мобильный и попытаться установить — попытка завершится неудачей. Необходимы дополнительные манипуляции с файлом apk перед переносом.
Необходимо выполнить выравнивание содержимого apk (aligning) и его подпись (sign).

Здесь частично будут использованы сведения из статьи medium.com/@sandeepcirusanagunla/decompile-and-recompile-an-android-apk-using-apktool-3d84c2055a82
Но так как, сведения из статьи немного устарели, как например, в части алгоритма шифрования, будут использоваться немного иные команды.

Алгоритм следующий.
1.Создаем ключ-пару, который «подпишем» наш apk:

keytool -genkeypair -keyalg DSA -keysize 2048 -keystore my-release-key.keystore -alias alias_name -validity 10000

Пароль можно задать любой как и данные, ввод которых можно пропускать, нажимая enter.

На выходе рядом с apk появится файл — ключ-пара:

2. Подпишем файл(signing), используя нашу ключ-пару.

jarsigner -verbose -sigalg SHA256withDSA -digestalg SHA256 -keystore my-release-key.keystore com-ordro.apk alias_name

В терминале увидим при успешном выполнении примерно следующий вывод:

Однако, если проверить подписанное приложение jarsigner -verify -verbose -certs com-ordro.apk может выскочить ошибка, которая в дальнейшем не позволит установиться приложению на мобильном:

Можно пойти по длинному пути и исправить ошибку с ключ-парой и сертификатами, но мы поступим проще. Подпишем и выровняем apk с помощью uber-apk-signer.

Скачав uber-apk-signer.jar в папку с готовым apk, выполним команду:

java -jar uber-apk-signer.jar -a com-ordro.apk

*Данная команда заменяет собой 2 предыдущих шага с выравниванием и подписанием.
Она использует все тот же zipalign.exe и создает ключ-пару. Если zipalign нет, то его нужно скачать и добавить его в PATH.

На выходе получим готовый apk, который уже можно устанавливать на мобильном:

ps. для тех кого интересует вопрос (как и меня) собственно по камере — можно ли с нее получать поток, в обход мобильного приложения — да, возможно rtsp:\\192.168.1.1:554
