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

1. Always verify ADB connection first — run adb devices and confirm a device is listed before proceeding.
2. 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 or running via if needed.
