Hey 84rt-design,

Thanks for contacting us regarding your Android packaging issue. After looking over the provided, they look very similar to this specific issue from [AnswerHub][1]. I would highly suggest that you read down this thread and verify you’re taking all the right steps to package your project for Android. It may come down to a point where you’ll want to back up your project and try it on another machine if you have one available, before taking the reformatting step as this other person has.
