title: Android Proximity Alert not working
body: <p>I know many guys asked this question but I feel helpless because I tried everything I know but still not working.</p>
  
  <p>I provide my last tried code that worked once after that it doesn't.</p>
  
  <pre><code>public class ProximityAlertActivity extends Activity {
  
  private static final long POINT_RADIUS = 100; // in Meters
  private static final long PROX_ALERT_EXPIRATION = -1; // It will never expire
  private static final String PROX_ALERT_INTENT = "com.androidmyway.demo.ProximityAlert";
  private LocationManager locationManager;
  private EditText latitudeEditText;
  private EditText longitudeEditText;
  private Button addAlertButton;
  
  @Override
  public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_proxymity);
  
          locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
  
          latitudeEditText = (EditText) findViewById(R.id.point_latitude);
          longitudeEditText = (EditText) findViewById(R.id.point_longitude);
          addAlertButton = (Button) findViewById(R.id.add_alert_button);
  
          addAlertButton.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                       addProximityAlert();
                }
          });
  
  }
  
  private void addProximityAlert() {
  
         double latitude = Double.parseDouble(latitudeEditText.getText().toString());
         double longitude = Double.parseDouble(longitudeEditText.getText().toString());
         Intent intent = new Intent(PROX_ALERT_INTENT);
         PendingIntent proximityIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
         locationManager.addProximityAlert(
                latitude, // the latitude of the central point of the alert region
                longitude, // the longitude of the central point of the alert region
                POINT_RADIUS, // the radius of the central point of the alert region, in meters
                PROX_ALERT_EXPIRATION, // time for this proximity alert, in milliseconds, or -1 to indicate no                           expiration
                proximityIntent // will be used to generate an Intent to fire when entry to or exit from the alert region is detected
         );       
  }
