Good day,

I've hit a roadblock that I'm struggling to troubleshoot. I attempted to upload a game to Google Play, but it was rejected for a reason that was explained poorly in Google's email. I fixed the things I think may have been the issues, and now I'm trying to build a new APK to try to upload. When I export the project, however, it doesn't create an APK, it creates a .zip file, which didn't happen the first time around. When I try to upload that file to the new APK, it refuses to take, telling me that "Your APK file name must end with '.apk'." I could download the applications to turn this into an APK, but why is this happening at all? Why is this happening with the second attempt? I'm trying to do exactly what I did the first time around, and this wasn't a problem.
