android:layout_width="match_parent">
<fragment xmlns:android="http://schemas.android.com/apk/res/android"

Kindly help in this case.

Answer

Don't include the whole play services library but use the one that you need, I think that replacing the line:

compile 'com.google.android.gms:play-services:9.2.0'

with:

compile 'com.google.android.gms:play-services-maps:9.2.0'

should solve your problem
