Keyboard doesnt go away when sending email on Android device using native.showPopup("mail", options)

Using the native.showPopup email I have incorporated email into my game.  However on Android device after the email is sent the Keyboard will never go away and one must exit the game.  

This does not happen on IOS devices, on IOS the keyboard goes away after email is sent.

Can someone please provide info on how to make keyboard disappear after email is sent?  Thank you!

Are you using “native.setKeyboardFocus( nil )” after the email is sent?

No I am not using that call, please explain how I can do this.  Right now I have it set up like in the docs:

local options =
{
to = “john.doe@somewhere.com”,
subject = “My High Score”,
body = “I scored over 9000!!! Can you do better?”,
attachment = { baseDir=system.DocumentsDirectory, filename=“Screenshot.png”, type=“image/png” },
}
native.showPopup( “mail”, options )

So how would I set it up so that when it sends I can know this than call native.setKeyboardFocus( nil )

Thank you for help!
