4.21 shipping APK Fail to start with 0 packaging errors

These has happen twice for two different projects. Packaging for development and deployment show 0 errors but
when I try to lunch to test the game it fails to start. With message —package-name->-keeps stooping. Does any one know what might stop shipping APK to open?

It’s better to give us some more information, a screenshot of the error would clarify a lot.

For now, I might have a solution.

(1) go to ‘Project Settings’. (2) Click on ‘Android’ under ‘Platforms’. (3) Make sure ‘Android Package Name’ has been
filled in.

Hopefully that solves the problem for you.

Ok thank you.
