rev-dex-dumper - Android DEX Dumper

Dump DEX files from a running Android application's memory using panda-dex-dumper via ADB.

Tool Location

The panda-dex-dumper binary is bundled in this skill's directory. Resolve its absolute path relative to this SKILL.md file:

skills/rev-dex-dumper/panda-dex-dumper

Workflow

1. Push the tool to device

adb push <path-to>/panda-dex-dumper /data/local/tmp/
adb shell chmod +x /data/local/tmp/panda-dex-dumper

2. Determine target package name

If the user provides a package name, use it directly. Otherwise, get the foreground app:

adb shell dumpsys activity top | grep 'ACTIVITY' | tail -1 | awk '{print $2}' | cut -d/ -f1

3. Run the dumper

adb shell "cd /data/local/tmp && ./panda-dex-dumper -p $(adb shell pidof <package_name>)"

The dumped DEX files are saved to /data/local/tmp/panda/ on the device.

4. Pull DEX files to host

adb pull /data/local/tmp/panda/ ./

Pull to the user's current working directory.

5. Clean up device cache

adb shell rm -rf /data/local/tmp/panda/
adb shell rm /data/local/tmp/panda-dex-dumper

Guidelines

Always verify ADB connection first — run adb devices and confirm a device is listed before proceeding.
Root may be required — panda-dex-dumper uses ptrace to attach to the target process. If the device is not rooted, the dump will fail. Suggest adb root or running via su if needed.
Wait for app to fully load — if the user is dumping a packed app, the real DEX is only available after the packer's class loader has decrypted it. Advise the user to navigate past the splash screen before dumping.
Handle pidof failure — if pidof returns empty, the app may not be running. Launch it first with adb shell monkey -p <package_name> -c android.intent.category.LAUNCHER 1.
Multiple DEX files are normal — packed apps often produce several DEX files. All files in /data/local/tmp/panda/ should be pulled.
Always clean up — remove both the dumped DEX files and the tool binary from the device after pulling results to avoid leaving artifacts.
