ClassyShark is a standalone tool for Android developers. It can reliably browse any Android executable and show important info such as class interfaces and members, dex counts and dependencies. The browser supports multiple formats including libraries (.dex, .aar, .so), executables (.apk, .jar, .class) and AndroidManifest (.xml).

Understand the contents of your APK

• Verify that the business crucial data is properly obfuscated
• Troubleshoot Proguard mis configs (various -keep* flags)
• Analyze obfuscated stack traces

Manage your APK dependencies

• Identify all your app dependencies, both Java and native
• Identify test depeendencies
• Generate stub testing classes
• Checking hidden APIs

Understand the contents of multidex apps

• Browse the content of each classes.dex file
• See the dex counts for packages, methods, classes, strings etc
• See method count for jars (to measure the dex cost of that jar)
• Dump dex string tables

Troublshoot JNI problems including:

• Identify missing native libraries
• Browse native methods per classes.dex

Troublshoot native code problems including:

• See native depedendencies
• See dynamic symbols

1. Open APK java -jar ClassyShark.jar -open <YOUR_APK.apk>
2. Export all generated data to a text file java -jar ClassyShark.jar -dump <BINARY_FILE>
3. Export generated file from a specific class to a text file java -jar ClassyShark.jar -dump <BINARY_FILE> <FULLY_QUALIFIED_CLASS_NAME>
4. Open ClassyShark and display a specific class in the GUI java -jar ClassyShark.jar -open <BINARY_FILE> <FULLY_QUALIFIED_CLASS_NAME>
5. Inspect APK java -jar ClassyShark.jar -inspect <YOUR_APK.apk>
6. Dump all strings (combined classes.dex string tables) from your APK java -jar ClassyShark.jar -stringdump <YOUR_APK.apk>

To run, grab the latest jar from [here] (https://github.com/google/android-classyshark/releases) and type java -jar ClassyShark.jar.
