The definitive guide to Android library development
summary
Explains why Android libraries are harder than they should be and gives concrete fixes: publish AAR + BOM to Maven, use the fat AAR plugin or publish submodules separately, run the Gradle dependencies task to find version clashes, handle okhttp version skew and protobuf java vs java‑lite collisions by excluding or repackaging, ship consumer ProGuard rules and a public.xml, enforce API stability with the binary compatibility plugin and API dumps, prefer small public surfaces and test the published artifact end‑to‑end.
