B4A Library GoogleMapsExtras

Yes this did the trick. Map looks correct. I think mapsforge determine tile size according to device. Maybe instead of displayModel = new FixedTileSizeDisplayModel(TILE_SIZE); we need to create displayModel = new DisplayModel(); and not set tile size explicite. But i don't know java and mapsforge lib

Is it possible that CustomUrlTileProvider don't accept redirections?

Hello
Why I cannot remove Circle? what is the code ? "gmapExtra.Remove" is wrong.
Thank you

Code:

Private gmapExtra As GoogleMapsExtras
Private co As CircleOptions

'Add Circle'
    co.Initialize
    co.Center2(Lati, Longi).Radius(3000).FillColor(Colors.ARGB(50,50,220,125)).StrokeColor(Colors.Black)
    gmapExtra.AddCircle(gmap, co)
  
'And now Remove Circle' 
    gmapExtra.Remove

Click to expand...

Dim c As Circle
c = gmapExtra.AddCircle(gmap, co)
c.Remove

OK here's my first version of a wrapper for the KML packages in the Android Maps Utils.

A simple b4a project that loads a KML file from file assets - works for me though the web based infowindow content of the KML is a fail!

B4X:

#Region  Project Attributes
   #ApplicationLabel: Android Maps Utils
   #VersionCode: 1
   #VersionName:
   'SupportedOrientations possible values: unspecified, landscape or portrait.
   #SupportedOrientations: unspecified
   #CanInstallToExternalStorage: False
   '   GoogleMaps additional jar
   #AdditionalJar: com.google.android.gms:play-services-maps
#End Region

#Region  Activity Attributes
   #FullScreen: False
   #IncludeTitle: True
#End Region

Sub Process_Globals

End Sub

Sub Globals
   Dim GoogleMap1 As GoogleMap
   Dim MapFragment1 As MapFragment
End Sub

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("Main")
  
   If Not(MapFragment1.IsGooglePlayServicesAvailable) Then
     Log("Google Play Services is not available")
     ToastMessageShow("Google Play Services is not available", False)
   End If
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub MapFragment1_Ready
   Log("MapFragment1_Ready")
   GoogleMap1=MapFragment1.GetMap
   If GoogleMap1.IsInitialized Then
     Dim CameraPosition1 As CameraPosition
     CameraPosition1.Initialize(52.7523, 0.4049, 10)
     GoogleMap1.AnimateCamera(CameraPosition1)
    
     Dim KMLLayer1 As KMLLayer
     KMLLayer1.Initialize(GoogleMap1, File.OpenInput(File.DirAssets, "75116131-1-KML0.simple.kml"))
     KMLLayer1.AddLayerToMap
    
     If KMLLayer1.HasContainers Then
       Dim Containers As List=KMLLayer1.GetContainers
       '   TODO
     End If
    
     If KMLLayer1.HasPlacemarks Then
       Dim Placemarks As List=KMLLayer1.GetPlacemarks
       '   TODO
     End If
    
   Else
     Log("Error initializing GoogleMap")
     ToastMessageShow("Error initializing GoogleMap", False)
   End If
End Sub

I'll attach this first version of my library, the simple demo project and a temporary updated version of GoogleMapsExtras for you all to have a look at.

I shall release a proper update to GoogleMapsExtras over the next week - if you want to try AndroidMapsUtils and use the MarkerOptions object then overwrite you current GoogleMapsExtras jar and xml files with the temporary ones.

@DonManfred
Thanks a lot, once i found the latest version of the play services jar i was able to get SLC to work.
Let's liase later in the week to turn this into a shared collaboration.

Martin.

Did you see the KML library in the list of libraries that will be jetified? Note that internal libraries will not be jetified.
