Unable to parse kml with gx:LatLonQuad node

[acespring78]

Hello. I have a kml file that uses the xmlns:gx="http://www.google.com/kml/ext/2.2" namespace and uses the gx:LatLonQuad node with the coordinates defining the lat/lon coordinates of the box, instead of LatLonBox

When loading this kml file to KmlLayer, it throws an exception because I believe it doesn't read the gx:LatLonQuad node, but instead is looking for LatLonBox to parse the north, south, east, and west nodes. The following exception trace is as follows:

java.lang.NullPointerException: Attempt to invoke virtual method 'double java.lang.Double.doubleValue()' on a null object reference
        at com.google.maps.android.data.kml.KmlFeatureParser.createLatLngBounds(KmlFeatureParser.java:452)

        at com.google.maps.android.data.kml.KmlLayer.<init>(KmlLayer.java:79)

This kml file works when loading to Google Earth by the way.

Is there plans to support gx:LatLonQuad in later releases?

Thanks for reporting. This was not something we were planning on adding, however, contributions are certainly welcome to get this working.

Would you mind sharing an example KML file / snippet in case someone wants to take this on?

Here's a sample. The icon field can be replaced with any image file, but the key item here is the gx:LatLonQuad node and the absence of the LatLonBox

Hi, do we know if there are still plans to support gx:LatLonQuad in the near future?
