Can you reverse-engineer an APK?

Can you reverse-engineer an APK?

It converts an APK file into a human-readable Java output. Even though the decompilation of an APK using JADX usually gives you fairly readable Java code, the decompilation process is lossy and you can’t simply recompile the app using Android Studio. If only APK reverse-engineering was this easy… So wait!

How do I reengineer APK files?

13 Answers

1. Download dex2jar tool from dex2jar.
2. Use the tool to convert the APK file to JAR: Windows: $ d2j-dex2jar.bat demo.apk dex2jar demo.apk -> ./demo-dex2jar.jar. MacOS / Linux: $ d2j-dex2jar.sh -f demo.apk -o demo.jar.
3. Once the JAR file is generated, use JD-GUI to open the JAR file. You will see the Java files.
