Determine the map's load status which can be: NOT_LOADED, FAILED_TO_LOAD, LOADING, LOADED.
How to use the sample
Tap on the refresh button in the top right of the screen to reload the ArcGISMap. The load status of the ArcGISMap will be displayed on screen.
How it works
Create an ArcGISMap and add it to a MapView.
Use ArcGISMap.addLoadStatusChangedListener() or ArcGISMap.getNewLoadStatus() to query the map's load status.
The LoadStatus is LOADED when any of the following criteria are met:
The map has a valid spatial reference.
The map has an an initial viewpoint.
One of the map's predefined layers has been created.
