Android地图v2 showInfoWindow（）导致崩溃，在com.google.android.gms.maps.model.Marker.showInfoWindow（未知来源）

Question

友

有人知道为什么marker.showInfoWindow（）方法会崩溃吗？使用以下错误代码。 当我不使用该方法时，一切正常，所有标记都可以在地图中点击，并且所有自定义信息窗口都会根据需要在用户点击时显示在屏幕上。

感谢您的帮助

private void addGoogleMapAdvertisementMarker(ValueObjectAdvertiserData valueObjectAdvertiserData) {

    // adds a single advertisement marker to the map and
    // stores the individual marker to the arraylist markers
   Marker marker = map.addMarker(new MarkerOptions()
            .position(new LatLng(valueObjectAdvertiserData.latitude, valueObjectAdvertiserData.longitude))
            .title(valueObjectAdvertiserData.headline)
            .snippet(valueObjectAdvertiserData.description)
            .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
    marker.showInfoWindow();

    markers.add(marker);
}
