XZ: Android application building practice + Principle elaboration

Based on the latest construction tool chain, this course takes the development and release of a page routing framework as the main line, combines actual practice with theory, and deeply learns Gradle’s popular compile-time annotation processing, bytecode peg and other advanced technologies, leading everyone to systematically master the knowledge of Android application construction and improve the development efficiency.

Technical language: Groovy/Java/Kotlin Android: Mac IDE: Android Studio 4.0+Gradle: 6.0+ Android Gradle Plugin: 4.1.0+
