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

bash

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:

bash

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

3. Run the dumper

bash

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

bash

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

Pull to the user's current working directory.

5. Clean up device cache

bash

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.
