Unreal Engine4, Deploy your game on Play Store

Hello. How to deploy a video game made with Unreal ENgine4?
I have already read the documentation on the subject but my problem persists.
Here, I just finished my first two games with Unreal Engine 4.
And it’s been several days since I try to deploy them on Play Store.
There seems to be a step next to which I went because when I try to install the application from Play Store, I get the message “Can not install the application [Name of the application]”.
I even did a small test project that did not include StaterContent, whose size was reduced to the maximum but the problem persists.
Can someone just write me all the steps of the creation of the APK until the deployment on PlayStore? (Preferably without having to send me back to the documentation, I already read it)
I’m a little hopeless.

First of all i have a question for you.

1-) Have you tried creating a apk of your game?
→ if you have → does it run?
→ if you havent → try doing it before uploading to playstore.

Hello.
Indeed, the APK does not install either. What can this be?
There, I compile twice. Once with OBB file and once with all data in the same file.
