This code is an Android application that demonstrates how to customize the map style and handle location permissions using the Nextbillion Maps SDK. Here's a summary of the code:

Initializing MapView:

  • The MapView is initialized by calling mapView.onCreate(savedInstanceState).

Location Permissions Handling:

  • The app checks if location permissions are granted using PermissionsManager.areLocationPermissionsGranted(this). If permissions are granted, the map is asynchronously loaded. Otherwise, the app requests location permissions using the PermissionsManager and handles the permission result in the onPermissionResult callback.

Switch Map Style:

  • The app provides a floating action button (FAB) to toggle the map style. When the FAB is clicked, the toggleMapStyle() method is called. It gets the current map style using nextbillionMap.getStyle() and switches between a dark and light style by setting the new style using
    • nextbillionMap.setStyle(new Style.Builder().fromUri(styleUrl)).

Tracking Current Location Automatically:

  • When the map is ready (onMapReady callback), the camera is positioned to a specific location and zoom level.

  • The map style is set to the light style, and the location component is activated using nextbillionMap.getLocationComponent().activateLocationComponent().

  • The location component is configured to use the default location engine and display a pulsing animation.

  • It is enabled and set to render mode COMPASS and camera mode TRACKING. The location component also listens for click and long-click events on the user's location.

    • locationComponent.setLocationComponentEnabled(true);
    • locationComponent.setRenderMode(RenderMode.COMPASS);
    • locationComponent.setCameraMode(CameraMode.TRACKING);

Additional lifecycle methods are implemented to manage the MapView, including onStart, onResume, onPause, onStop, onSaveInstanceState, onDestroy, and onLowMemory.
