Android Question GoogleMaps doesn't work

[Roger C]

Hi,

I'm trying out Google Maps and found this tutorial:
https://www.b4x.com/android/forum/threads/google-maps.63930/

It just shows a white screen and no map.
So i searched and found this (among others):
https://www.b4x.com/android/forum/threads/google-map-v2-white-map-on-device.56962/

I tried the runtime permission check too:
https://www.b4x.com/android/forum/t...ty-exemptions-on-android-7.88995/#post-563422

No luck. Still white screen with Google-logo and +/- buttons, but no map...

Problem is that Google API pages doesn't look at all as they used to when i programmed 3-4 years ago and not like the examples in the forum.
Maps API comes in a new version sine July 2018 too and I don't know if that has anything to do with it.... Now it's called Maps SDK for Android.

So I don't know what's wrong; Google API registration, GoogleMaps v2.02, missing files, ....

I have GoogleMaps v2.02, Reflection v2.40 and RunTimePermission v1.10 as libraries. Don't know what to do...

End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    Activity.LoadLayout("MapView")
    If MapFragment1.IsGooglePlayServicesAvailable = False Then
        ToastMessageShow("Please install Google Play Services.", True)
    End If
    'Log(IsActivityAvailable("com.google.android.gms"))
    
End Sub


Sub MapFragment1_Ready
    gmap = MapFragment1.GetMap
    rp.CheckAndRequest(rp.PERMISSION_ACCESS_FINE_LOCATION)
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
    gmap.MyLocationEnabled = Result
    Dim m1 As Marker = gmap.AddMarker(10, 30, "test")
    m1.Snippet = "This is the snippet"
End Sub

Sub Activity_PermissionResult (Permission As String, Result As Boolean)
    If Permission = rp.PERMISSION_ACCESS_FINE_LOCATION Then
        gmap.MyLocationEnabled = Result
    End If
End Sub

And here's the logfile. Full of errors.
