Answer 1

I guess this problem can be resolved by removing duplicate dependencies,before removing the duplicate dependencies, you should check your modules by this command:

gradlew -q dependencies yourProject:dependencies --configuration compile

refer to this answer:duplicate dependencies problem

Hope it can help you :)

Answer 2

Looks like duplicate dependency problem, remove "compile 'com.android.support:recyclerview-v7:23.1.0@aar" and it'll be fine.
