Android studio 3.3 has entered the Beta2 phase. Compared with version 3.2, in addition to adding the option of analyzing memory configuration tracking, Android App Bundles also start to support Instant Apps. The build system has also been updated to use the SDK build tool 28.0.3 by default. In addition, the program code compressor Proguard has been replaced with R8. The big web companies continue to work on reducing the size of Android applications. Starting with Android Studio 3.2, a new distribution format for Android, Android App Bundle, allows users to install applications by downloading only the parts of the device that are needed to significantly reduce the size of applications. Now the web giants are making R8 the default code compressor for Android Studio.
