## What it is
dpt-shell is an Android Dex protection shell that hollows out DEX method implementations and reconstructs them at runtime to protect APK/AAB packages from reverse engineering. It is a Java command-line tool with runtime anti-debugging, Frida detection, and signature verification features.

## Use cases
- protect an android apk from reverse engineering
- hollow out dex methods in an android app
- add anti-debugging and frida detection to an apk
- obfuscate android app code at the dex level
- protect an aab bundle before release
- verify app signature at runtime on android

## When to choose
- you need to harden an Android APK or AAB against static analysis and tampering
- you want runtime anti-debug, Frida detection, or CRC/signature checks baked into your app
- you prefer a simple CLI you can integrate into a build pipeline

## When to avoid
- you need general-purpose code obfuscation rather than DEX method protection (use ProGuard/R8)
- your target is not Android
- you cannot accept the startup performance or compatibility trade-offs of a protection shell
