Android Studio – UNEXPECTED TOP-LEVEL EXCEPTION:

Like everyone else said here, the support library (com.android.support) is being included more than once in your project. Try adding this in your build.gradle at the root level and it should exclude the support library from being exported via other project dependencies.

configurations {
    all*.exclude group: 'com.android.support', module: 'support-v4'
}

If you have more then one support libs included in the dependencies like this, you may want to remove one of them:enter image description here
