Answer 1

You need to request the FINE_LOCATION permission, just like the exception says.

Answer 2

Your logcat clearly said

Caused by: java.lang.SecurityException: "gps" location provider requires ACCESS_FINE_LOCATION permission. 05-14 01:20:39.230: E/AndroidRuntime(1177):

You need to add below permission in your manifest.xml file

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

Answer 3

The log says it all :

 location provider requires ACCESS_FINE_LOCATION permission.

Add this permission in AndroidManifest.xml and your app will work fine.
