Android Question Keyboard remains after Gmail closes

[terminator2]

The following code opens the gMail app and sends a message as expected. When I hit send the soft keyboard (that was loaded by the Gmail app) remains open and covers half my app until I manually close it. How do I force the keyboard to go away along with the dismissed mail app?

Public Sub contactUs(mapData As Map)

Private Message As Email
Public p As Phone

Message.Body = mapData.Get("body")
Message.To.Add("Someone@gmail.com")
Message.Subject = "Message from My App"
StartActivity(Message.GetIntent) ​

End Sub​

I managed to do it with:

Sub Activity_Resume

IME.HideKeyboard​

End Sub​

On each activity that calls Gmail App.

I still don't know why Gmail didn't close the keyboard when it lost focus.
