[ivanomonti]

I follow my recommendations but here I go in the darkest, I updated the libreies, performed every single step, api keys, libraries, code, but when I run it all goes crashing to give me a mistake.

some birth mistakes, but I also downloaded other examples with the same problem

You should never initialize MapFragment.

I'm not sure which tutorial you followed, but you should follow this one: https://www.b4x.com/android/forum/threads/google-maps.63930/

I design my layout by code but it looks like you are using design, how can I create a drawing for MapFragment and add that view to my code?
I can not now destroy this code to add a map, you need to have a simpler solution using only the code!

    Dim pMap As Panel
    pMap.Initialize("pmap")
   
    panel2.Panel.AddView(pMap,0,0,panel2.Panel.Width,panel2.Panel.Height)
   
    pMap.AddView(MapFragment1,0,0,pMap.Width,pMap.Height)
   
    If MapFragment1.IsGooglePlayServicesAvailable = False Then
        ToastMessageShow("Please install Google Play Services.", True)
    End If

even following your advice I mistake me by crashing application, but without giving me error in the log

You should follow the steps from the tutorial. Your manifest code is wrong.

Make sure to follow the B4A v6+ steps.
