The Android Gradle Plugin provides various options for bytecode transformations, including AspectJ, ASM, Javassist, and others. The plugin's TransformAction and Transform classesWith APIs allow developers to inject custom code into the build process. To implement bytecode instrumentation using ASM, developers must register a ClassVisitorFactory with the Transform classesWith API, providing a custom class visitor that implements the `createClassVisitor` method. This visitor defines how to transform bytecode instructions and is interested in instrumenting specific classes annotated with @Dao. The InstrumentationParameters are used as Gradle inputs to pass information from the plugin to the ClassVisitorFactory. Developers can also use the new AGP transform APIs, which handle full/incremental builds on their own and offer a great API surface via ASM.
