I have a Fire Phone and am trying to develop an app that works with Firefly. During development, the app itself worked fine and I had no trouble installing it until we incorporated the Firefly SDK, at which point my Fire Phone refuses to install the app. Take Firefly out, it installs fine. Put it back in, no go. Any idea what the problem might be? What's a good alternative for testing to see how the .apk works with Firefly? Thanks for your help!
