GeoJsonLayer

A class that allows the developer to import GeoJSON data, style it and interact with the imported data.

To create a new GeoJsonLayer from a resource stored locally GeoJsonLayer layer = new GeoJsonLayer(getMap(), R.raw.resource, getApplicationContext());

To render the imported GeoJSON data onto the layer layer.addLayerToMap();

To remove the rendered data from the layer layer.removeLayerFromMap();
