Hello nithin.warier,

the first thing to check is where the NullPointerException happens.

Maybe you forgot to add the permissions to the AndroidManifest.xml:
Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1.     <uses-permission android:name="android.permission.ACCESS_LOCATION"/>
  2.     <uses-permission android:name="android.permission.ACCESS_GPS"/>
