Unfortunately, your project doesn't work with my equipment.
I get an error in line 55 in HttpUtils2Service: Log(Response.GetString("UTF8"))
From the help, it is deprecated for devices Android 4+.
I think that you should switch Http to
OkHttp library.
But from what i have seen, you load the layout file in Activity_Resume.
You must move it to Activity_Create, out of If FirstTime.
Sub Activity_Create(FirstTime As Boolean)
Activity.LoadLayout("Main")
End Sub
