Failed to resolve: android.arch.lifecycle:common-java8:1.0.3
Failed to resolve: android.arch.lifecycle:extensions:1.0.3

Answer 1

Program type already present: android.arch.lifecycle.LiveData$LifecycleBoundObserver
Message{kind=ERROR, text=Program type already present: android.arch.lifecycle.LiveData$LifecycleBoundObserver, sources=[Unknown source file], tool name=Optional.of(D8)}
