[Bug] IconGenerator with KLM Layer crashes while tapping on the Icon

[dominikue]

Summary:

I want to show a KML Layer and the IconGenerator.

Steps to reproduce:
Create a KML File as layer and a Icon with the example code from the IconGenerator.
If the user tap on the icon, the apps crashes. Without the kml layers it is working.

  // Adds KML File
    KmlLayer kmlLayer = null;
    try {
        kmlLayer = new KmlLayer(mMap, R.raw.overlay_stadtmitte, getApplicationContext());
        kmlLayer.addLayerToMap();
    } catch (XmlPullParserException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

   // Add a marker in Darmstadt and move the camera
    LatLng darmstadt = new LatLng(49.877572, 8.654379);
    mMap.moveCamera(CameraUpdateFactory.newLatLng(darmstadt));
    mMap.moveCamera(CameraUpdateFactory.zoomTo(14));


    // Add a IconLabel
    IconGenerator iconFactory = new IconGenerator(this);
    addIcon(iconFactory, "Default", new LatLng(49.877571, 8.654373));



}

private void addIcon(IconGenerator iconFactory, CharSequence text, LatLng position) {
    MarkerOptions markerOptions = new MarkerOptions().
            icon(BitmapDescriptorFactory.fromBitmap(iconFactory.makeIcon(text))).
            position(position).
            anchor(iconFactory.getAnchorU(), iconFactory.getAnchorV());

    mMap.addMarker(markerOptions);
}

Expected behavior:

The App shows the Icon and the KML Layer without problems.

Observed behavior:

Device and Android version:

Nexus 6p with Android 7. The App is <4.2 Android.

Screenshots:

Can be created by pressing the Volume Down and Power Button at the same time on Android 4.0 and higher.

I think this is the same as the one we posted, but under different behaviour - #327

How is your KML formatted, with name and description nodes? Please check the #327 and see if you can replicate it once with name and description and once without description and some nodes with description.
