I created my application on the Unity platform, decided not to bother and create something simple. One thought occurred to me, to make the Multiplication Table, I watched video tutorials and created (but it was the easiest if you compare what happened next).
After the creation, it was necessary to knock down the game, but I got a lot of errors and did not know how to fix them, I looked through many forums and there were no answers either. Do you ask how you fixed these errors? Just by accident. I decided to reinstall the JDK earlier version.
After that, I downloaded to Google Play. When I downloaded and published the version, I installed the Multiplication Table on the phone, started testing, and realized that I had a lot of flaws that I soon fixed, but the most interesting thing that I understood when downloading The new version (with corrected defects) they are not published immediately, but only within 2 hours.
That's the hard way I created this application, and most importantly, the "highlight" of my application is that there is no advertising in it at all, which is very convenient for users.
Good luck, colleagues.
