Android Studio 3.0 breaking changes

[tobrun]

Google recently announced Android Studio 3.0 on Google I/O 2017. This major version update contains a couple of breaking changes. While we're currently withholding doing the update, I'm tracking these changes in the meantime here for easy of tracking / implementation:

• Google migrates to their own maven repository in favour of support repository
  • add maven { url 'https://maven.google.com' } to the build.gradle -> update: now just google()
  • look into CircleCI configuration changes for the base image
• replace compile statements with implementation in build.gradle
• enable java 8 language features, refactor lamba
• TBA

Update: migration guide is here
