# APK decompilers
|
|
|
|
### [JD-Gui](https://github.com/java-decompiler/jd-gui)
|
|
|
|
First famous gui Java decompiler, you could use it to investigate the Java code from the APK once you have obtained it.
|
|
|
|
### [Jadx](https://github.com/skylot/jadx)
|
|
|
|
Buildin Java \(multi-platform\)and at this moment I think it's the recommended one.
|
|
Just **download** the **latest** version and execute it from the _**bin**_ folder:
|
|
|
|
```text
|
|
jadx-gui
|
|
```
|
|
|
|
Using the GUI you can perform **text search**, go to the **functions definitions** \(_CTRL + left click_ on the function\) and cross refs \(_right click_ --> _Find Usage_\)
|
|
|
|
If you **only want** the **java code** but without using a GUI a very easy way is to use the jadx cli tool:
|
|
|
|
```text
|
|
jadx app.apk
|
|
```
|
|
|
|
Some **interesting options of jadx** \(GUI and CLI versions\) are:
|
|
|
|
```text
|
|
-d <path to output dir>
|
|
--no-res #No resources
|
|
--no-src #No source code
|
|
--no-imports #Always write entire package name (very useful to know where is the function that you might want to hook)
|
|
```
|
|
|
|
### [GDA-android-reversing-Tool](https://github.com/charles2gan/GDA-android-reversing-Tool)
|
|
|
|
GDA is also a powerful and fast reverse analysis platform. Which does not only supports the basic decompiling operation, but also many excellent functions like **Malicious behavior detection, Privacy leaking detection, Vulnerability detection, Path solving, Packer identification, Variable tracking analysis, Deobfuscation, Python& Java scripts, Device memory extraction, Data decryption and encryption** etc**.**
|
|
|
|
**Only for Windows.**
|
|
|
|
|
|
|
|
### [Bytecode-Viewer](https://github.com/Konloch/bytecode-viewer/releases)
|
|
|
|
Another **interesting tool to make a Static analysis is**: [**bytecode-viewer**](https://github.com/Konloch/bytecode-viewer/releases)**.** It allows you to decompile the APK using **several decompilers at the same time**. Then, you can see for example, 2 different Java decompilers and one Smali decompiler. It allows you also to **modify** the code:
|
|
|
|
|
|
|
|
If you modify the code, then you can **export it**.
|
|
One bad thing of bytecode-viewer is that it **doesn't have references** or **cross-references.**
