checker-qual-android contains annotations (type qualifiers) that a programmer writes to specify Java code for type-checking by the Checker Framework. The checker-qual-android artifact is identical to the checker-qual artifact, except that in checker-qual-android annotations have classfile retention. The default Android Gradle plugin retains types annotated with runtime annotations in the main dex, but strips out class-retention annotations.

There is a newer version: 3.49.1-eisop1
