ZHANG Dapeng 755a22790b android/android-interop-testing/examples: upgrade android plugin ... This resolves #5523 While bumping `com.android.tools.build:gradle:3.1.2` to `3.3.0`, some other plugins/artifacts/maven repo/buildscripts have to be updated: - gradle (wrapper) need to upgrade to 4.10.x - protobuf gradle plugin need to bump a version compatible with gradle version. - need add `google()` and `jcenter()` repos for android (otherwise `com.android.tools.build:aapt2:3.3.0x` and `trove4j` will not be found resp.) - need to accept license for Android "build-tools;28.0.3" in kokoro env.		2019-04-02 14:52:27 -07:00
