I was packaging it up last night for release on Google Play. At first I wasn't using the b4a license key assignment feature. I was using the command line as described by Google Play docs. One of my release test versions may have 2 licence keys - the debug key and an actual valid license key. That may be the one on my phone. When I try to uninstall it, it does nothing. It just puts me back to the "apps" screen.
And not to be contradictory but it can have 2 license keys installed based on the cockemayme way I was doing things...Namely, I created the app with the default debug key in b4a then I added another license key at the command line. The Google Play error message was that I had two license keys in my apk.
I just uninstalled it by way of the menu option. I didn't even know it was available. Thanks so much for your help. Sorry if this was a waste of time. Also, that code of yours on email with intents was great. I used it. Thanks again.
