## What it is
Walle is a tool from Meituan-Dianping for generating Android channel (multi-market distribution) APK packages under the APK Signature Scheme V2. It embeds custom channel information into the APK Signature Block, works as a Gradle plugin or a standalone command-line/HTTP tool, and is far faster than repackaging per channel.

## Use cases
- generate channel-specific APKs for Android app distribution
- embed channel metadata into APKs without breaking V2 signatures
- read the channel name at runtime inside an Android app
- integrate channel packaging into a Gradle build
- serve channel APK generation over HTTP for build systems

## When to choose
- you distribute your Android app through multiple Chinese app stores and need many channel builds quickly
- your APKs use APK Signature Scheme V2 and legacy repackaging tools break the signature
- you want channel packaging integrated into Gradle or as a CLI step in CI

## When to avoid
- you do not need multi-channel APK distribution
- your APKs are signed only with V1 scheme or you target other platforms
- you need actively developed tooling with recent Android Gradle Plugin compatibility guarantees
