title: How to show multiple markers on MapFragment in Google Map API v2?
body: <p>I am using <code>Google Map API v2</code> in my application to show Maps.</p>
  
  <p>I have followed all the steps, that is to be followed to enable Google Map in my application.</p>
  
  <pre><code>public class PinLocationOnMapView extends FragmentActivity {
  
      private double mLatitude = 0.0, mLongitude = 0.0;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
  
          SupportMapFragment fragment = SupportMapFragment.newInstance();
          getSupportFragmentManager().beginTransaction()
                  .add(android.R.id.content, fragment).commit();
      }
  }
  </code></pre>
  
  <p>If I use this code, it shows me map, but if I provide my latitude/longitude values, map tiles does not load, and I see only white tiles. </p>
  
  <p>Following is the code written in onCreate() of above class:</p>
  
  <pre><code> if (getIntent().getExtras() != null) {
              final Bundle bundle = getIntent().getBundleExtra("LOCATION");
              mLatitude = bundle.getDouble("LATITUDE");
              mLongitude = bundle.getDouble("LONGITUDE");
          } else {
              finish();
          }
  
          GoogleMapOptions options = new GoogleMapOptions();
          LatLng latLng = new LatLng(mLatitude, mLongitude);
          CameraPosition cameraPosition;// = new CameraPosition(latLng, 0, 0, 0);
          cameraPosition = CameraPosition.fromLatLngZoom(latLng, (float) 14.0);
  
          options.mapType(GoogleMap.MAP_TYPE_SATELLITE).camera(cameraPosition)
                  .zoomControlsEnabled(true).zoomGesturesEnabled(true);
  
          SupportMapFragment fragment = SupportMapFragment.newInstance(options);
          getSupportFragmentManager().beginTransaction()
                  .add(android.R.id.content, fragment).commit(); 
  </code></pre>
  
  <p>Also, I have a list of lat/long values. I want to show them on <code>MapFragment</code>, <strong>how to show multiple markers on <code>MapFragment</code></strong>? </p>
  
  <p>I tried with <code>MapView</code> and <code>ItemizedOverlay</code>, but it didn't work for me. I believe I have correctly created the <code>SHA1</code> key to get the <code>API</code> key, because if that was wrong, I could not see map using <code>MapFragment</code> as well, but I can see that if I don't pass the lat/log value.</p>
