title: Google Maps Android API v2 detect long press on map and add marker not working
body: <p>I want to add a marker on map with long press.</p>
  
  <p><code>Toast</code> in <code>onMapClick()</code> was display with normal tap. But long press is not working. <code>Toast</code> in <code>onMapLongClick()</code> is not displayed with long press. Also marker is not displayed on map.</p>
  
  <p>I'm using <code>SupportMapFragment</code> because I want to use my application on Android 2.x devices. I have tested my app on Nexus One which has Android version 2.3.7.</p>
  
  <p>This is my code.</p>
  
  <pre><code>public class MainActivity extends FragmentActivity implements
          OnMapClickListener, OnMapLongClickListener {
  
      final int RQS_GooglePlayServices = 1;
      private GoogleMap myMap;
  
      Location myLocation;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          FragmentManager myFragmentManager = getSupportFragmentManager();
          SupportMapFragment mySupportMapFragment = (SupportMapFragment) myFragmentManager
                  .findFragmentById(R.id.map);
          myMap = mySupportMapFragment.getMap();
  
          myMap.setMyLocationEnabled(true);
  
          myMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
          // myMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
          // myMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
          // myMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
  
          myMap.setOnMapClickListener(this);
          myMap.setOnMapLongClickListener(this);
  
      }
  
      @Override
      protected void onResume() {
          super.onResume();
  
          int resultCode = GooglePlayServicesUtil
                  .isGooglePlayServicesAvailable(getApplicationContext());
  
          if (resultCode == ConnectionResult.SUCCESS) {
              Toast.makeText(getApplicationContext(),
                      "isGooglePlayServicesAvailable SUCCESS", Toast.LENGTH_LONG)
                      .show();
          } else {
              GooglePlayServicesUtil.getErrorDialog(resultCode, this,
                      RQS_GooglePlayServices);
          }
  
      }
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          // Inflate the menu; this adds items to the action bar if it is present.
          getMenuInflater().inflate(R.menu.main, menu);
          return true;
      }
  
      @Override
      public void onMapClick(LatLng point) {
  
          myMap.animateCamera(CameraUpdateFactory.newLatLng(point));
  
          Toast.makeText(getApplicationContext(), point.toString(),
                  Toast.LENGTH_LONG).show();
  
  
      }
  
      @Override
      public void onMapLongClick(LatLng point) {
  
          myMap.addMarker(new MarkerOptions().position(point).title(
                  point.toString()));
  
          Toast.makeText(getApplicationContext(),
                  "New marker added@" + point.toString(), Toast.LENGTH_LONG)
                  .show();
  
      }
  
  }
  </code></pre>
  
  <p>How can I solve this ?</p>
