Hey all, I wrote a simple hello world app based on the number guessing game, and am trying to send to my son via email as an attachment. He knows alot more than me about Android devices, but it will not install on his device. Just so I know the process, I compile and run (Alt + 1), this works and deploys to the emulator or my device via USB. Also, I created a signature file, but at first I didn't have this. As it compiles, I see in the details that the signature file is installed. Am I missing something? Is there some other setting I am needing? Thanks.
