Here exist an error!

compile 'com.android.support:appcompat-v7:25.3.1'

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 25.3.1, 25.3.0. Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'

Seeing this Examples include 'com.android.support:animated-vector-drawable:25.3.0' and 'com.android.support:mediarouter-v7:24.0.0'

Just add these codes in dependencies, make sure that versions are same.

Just update build.gradle file with this :-

compile 'com.android.support:animated-vector-drawable:25.3.1'
compile 'com.android.support:mediarouter-v7:25.3.1'
