Using a content smaller
I might be late with my answer but here goes. I was having a similar problem, but none of the above mentioned solutions worked for me. In the end I fixed it by using version 23 of the support library.
...
compileSdkVersion 23
...
targetSdkVersion 23
...
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:support-v4:23.1.0'
compile 'com.android.support:design:23.1.0'
