Class RuntimeAnnotatedClassCollector

java.lang.Object

com.android.builder.dexing.RuntimeAnnotatedClassCollector

public class RuntimeAnnotatedClassCollector
extends java.lang.Object

A collector for runtime annotated classes.

Provides collectClasses(Collection) which given a collection of jars and directories returns the set of classes that should be kept according to the predicate.

The predicate to determine whether to keep the class is injected in the constructor.

In legacy multidex, by default all classes annotated with a runtime-retention annotation are kept in the main dex, to avoid issues with reflection.

See Issue 78144.
