Developer API

Writing....

Hunter is a framework to develop android gradle plugin based on ASM and Gradle Transform API. You can use Hunter to develop more plugin to monitor your app, enhance 3rd-dependency, enhance android framework.

Plugins based on Hunter support incremental and concurrent compile, so you don't need to afraid of extra build time.

If you want use Hunter to develop a new android gradle plugin, You can use HunterTransform and BaseWeaver,

HunterTransform: It's a incremental and concurrent tool to transport all classes and jars to BaseWeaver. It makes plugins more faster.

BaseWeaver: It's a tool to simplify useage of asm. you just need to tell BaseWeaver which class you want to handle, and provide a ClassWriter to weave the bytecode
