title: creating CustomInfoWindow in google map v2
body: <p>I'm having problem creating my own CustomInfoWindow. getting exception without know where &amp; why</p>
  
  <p>this is my simple customInfoWindow class</p>
  
  <pre><code>public class CustomInfoWindow implements InfoWindowAdapter {
  
  private LayoutInflater mInflater;
  
  public CustomInfoWindow(LayoutInflater inflater) {
      this.mInflater=inflater;
  
  }
  
  
  @Override
  public View getInfoContents(Marker marker) {
      View popup = mInflater.inflate(R.layout.info_window_layout, null);
      TextView tv=(TextView)popup.findViewById(R.id.title);
      tv.setText(marker.getTitle());
      tv=(TextView)popup.findViewById(R.id.address);
      tv.setText(marker.getSnippet());
  
      return popup;
  }
  
  @Override
  public View getInfoWindow(Marker marker) {
      View popup = mInflater.inflate(R.layout.info_window_layout, null);
      TextView tv=(TextView)popup.findViewById(R.id.title);
      tv.setText(marker.getTitle());
      tv=(TextView)popup.findViewById(R.id.address);
      tv.setText(marker.getSnippet());
  
      return popup;
  }
  </code></pre>
  
  <p>}</p>
  
  <p>I'm setting it here. (MainActivity)</p>
  
  <pre><code>mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
              .getMap();
      mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
      mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(
              Statics.LAT_TLV, Statics.LON_TLV), 13));
  
      CustomInfoWindow customInfoWindow = new CustomInfoWindow(getLayoutInflater());
      mMap.setInfoWindowAdapter(customInfoWindow);
  </code></pre>
  
  <p>I didn't implement the onMarkerClick method.
  the map loads ok with the markers (about 40), but when i click on one of the markers i get:</p>
