Answer 1

You need to check that you have inserted v4 library and compile library? You must not repeat library in your app or your dependence program.

delete the repeat library so that just one V4 remains.

in your app dir build.gradle file add this command:

android{


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

}

it works for me! You can try it!
