Specify requirement for OpenGL ES version 2

The Google Maps Android API uses OpenGL ES version 2 to render the map.
If OpenGL ES version 2 is not installed, your map will not appear.
We recommend that you add the following <uses-feature> element as a child of the <manifest> element in AndroidManifest.xml:

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />
