Answer 2

Add this tag before the uses-permision tags in the AndroidManifest file:

<permission
    android:name="com.vallabh.googlemapspractice.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

And add this uses-permission tag:

<uses-permission android:name="com.vallabh.googlemapspractice.permission.MAPS_RECEIVE" />
