Displaying a dialog in android to prompt user to enable GPS

The following code snippet can be used to prompt a user to enable GPS in android:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

import android.app.Activity; import android.app.AlertDialog; import android.content.Context; import android.content.DialogInterface; import android.content.Intent; import android.provider.Settings; class Utils { public static void displayPromptForEnablingGPS( final Activity activity) { final AlertDialog.Builder builder = new AlertDialog.Builder(activity); final String action = Settings.ACTION_LOCATION_SOURCE_SETTINGS; final String message = "Enable either GPS or any other location" + " service to find current location. Click OK to go to" + " location services settings to let you do so."; builder.setMessage(message) .setPositiveButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface d, int id) { activity.startActivity(new Intent(action)); d.dismiss(); } }) .setNegativeButton("Cancel", new DialogInterface.OnClickListener() { public void onClick(DialogInterface d, int id) { d.cancel(); } }); builder.create().show(); } }

As you can see, the action Settings.ACTION_LOCATION_SOURCE_SETTINGS is used to start the activity to change the GPS/Location source settings.
