Hello Map

_|

In this example you will learn how to render an interactive map centered on a desired location. The map is fully 3D, supporting pan, pinch-zoom, rotate and tilt.

Map View

Map Display and Cleanup

The following code outlines the main activity, which displays the map and handles resource clean-up.

The MainActivity overrides the onCreate function which instantiates and loads the map: setContentView(R.layout.activity_main) as defined in res/layout/activity_main.xml.

MainActivity.kt

class MainActivity : AppCompatActivity()
{
    override fun onCreate(savedInstanceState: Bundle?)
    {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }

    override fun onDestroy()
    {
        super.onDestroy()

        // Release the SDK.
        GemSdk.release()
    }

}

The com.magiclane.sdk.core.GemSurfaceView is a custom View that displays the map, part of Magic Lane's SDK.
