I can not understand,
Android B4x 7.30
android emulator as I do not have a device

 

[Erel]

Based on the error message this library depends on Google Play Services which is not installed on the emulator.

I updated everything sdk android, I do not understand!

It is not related to Android SDK. The library that you are using depends on Google Play Services "app" being installed on the device. I recommend you to use a real device it will be simpler.

You can also call Google geocoding REST API. It is quite simple:

Sub PlaceToLatLon(Place As String) As ResumableSub
   Dim res() As Double = Array As Double(9999, 9999)
   Dim j As HttpJob
   j.Initialize("", Me)
   j.Download2("https://maps.googleapis.com/maps/api/geocode/json", Array As String("key", API_KEY, "address", Place))
   Wait For (j) JobDone(j As HttpJob)
   If j.Success Then
     Dim jp As JSONParser
     jp.Initialize(j.GetString)
     Dim m As Map = jp.NextObject
     If m.Get("status") = "OK" Then
       Dim results As List = m.Get("results")
       If results.Size > 0 Then
         Dim first As Map = results.Get(0)
         Dim geometry As Map = first.Get("geometry")
         Dim location As Map = geometry.Get("location")
         res(0) = location.Get("lat")
         res(1) = location.Get("lng")
       End If
     End If
   Else
     Log("Error!")
   End If
   j.Release
   Return res
End Sub

Usage example:

Wait For(PlaceToLatLon("Israel Yodfat")) Complete (ll() As Double)
If ll(0) <> 9999 Then
   Log("Location: " & ll(0) & ", " & ll(1))
Else
  Log("Failed to geocode")
End If
