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

    <uses-permission android:name="android.permission.ACCESS_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_GPS"/>
