I imagine it's really trivial to download the Android APK, decompile it into it's source code, modify the code, and then push the modified app back on to the phone. You can be anyone you want to be. This idea does fall apart after the officer looks up the license number on his device. Do you think this would work at taverns?

In the US I’ve been to plenty of bars and grocery stores with ID scanners. I’d imagine this would be no different.
