I want to find current location in my android application. It is an image based search application in which the current location has to be shown
<p>If i click on 'Find current location' button, it is showing "Sorry! Force to close". I want to display latitude and longitude. GPS is turned on in my mobile. Still its showing the error message. Whats wrong with my code?</p>

<pre><code>public class CurrentLocation extends Activity {

private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1; // in Meters
