Uploading apk to amazon?

Question

Android

I created a game for android and decided to post it, went to Amazon, went through a bunch of paperwork, in the end, it remains to download the apk file and then download and 7-8.sec check and displays invalid input (invalid input). I just can't figure out what to do with it. Tried using zingling (via android studio), I read it somewhere. But the site refuses to accept the file after that. To be honest, I tried to put it in the AppStore, but you need to download xcode there, and I have windows 8.1. And Google Play has no money to lay out. In general, I tried on the game, and, as always, the wall with the inscription "Severe Reality 'signature' life" hands dropped, and the game would be okay, ap-blunder, I hunched over it for 3-4 years (I'm a beginner, I was then a complete zero and programming and in Unity itself and started right away with a difficult one, but pulled it all the same). Life gave me a cruel heart :(

In general - most likely - some kind of garbage in the manifest. For example, no versionName/versionCode is specified, or a signature.
