Solution 1:

MapEngine must be initialized before it can be used. It should be done in the main thread. MapEngine is automatically initialized for your application by using AndroidXMapFragment. AndroidXMapFragment is a fragment class applications can use as a UI module in an activity for map display. However, if your application does not use AndroidXMapFragment classes, then the application should initialize the MapEngine directly before using any HERE APIs. You can do this by calling MapEngine.init(ApplicationContext, OnEngineInitListener) as shown below:

MapEngine mapEngine = MapEngine.getInstance(); ApplicationContext appContext = new ApplicationContext(context); mapEngine.init(appContext, new OnEngineInitListener() {   @Override   public void onEngineInitializationCompleted(Error error) {
    if (error == OnEngineInitListener.Error.NONE) {
      // Post initialization code goes here
    } else {
      // handle factory initialization failure
    }   } });
