Android Question B4a Emulator

I use my phone and also my tablet. Connect via USB. Go to Settings | Developer Options. Turn it on.
Also turn on USB debugging in your phone.
In your B4A program, make Log statements as such. Change to suit your need about the script variable.

If FirstTime Then
Log("Log.Main.Activity_Create First Time")
Else
Log("Log.Main.Activity_Create Not First Time")
End If

Run the program and look at the Logs tab.

You need to create an AVD from AVD Manager. It is included in B4A Sdk Manager.
