<supports-screens android:largeScreens="true" 
    android:normalScreens="true"

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("lyCollectGPS")
    If MapFragment1.IsGooglePlayServicesAvailable = False Then
        ToastMessageShow("Please install Google Play Services.", True)
      End If
End Sub
Sub MapFragment1_Ready
    gmap = MapFragment1.GetMap
    Starter.rp.CheckAndRequest(Starter.rp.PERMISSION_ACCESS_FINE_LOCATION)
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
    gmap.GetUiSettings.MyLocationButtonEnabled=True

I already follow the the below link still is the same:-

The output still is white map.

Please advise.


- Register your app in Google developer console: https://console.developers.google.com
You need to enable Google Maps Android API.
Then click on Credentials -> Create Credentials -> API Key -> Android Key.
You should get a key that looks like: AIzaSyCmFHamGE0O0BvxxxxxxxxXbTCSrjFVg-Q
