Didn't want to build. Doesn't want to run the game

I made my game, it was a problem to be able to build it, I posted it on the play store and when I downloaded it, it didn’t run on my cell phone, I asked a foreigner in a unity group to download it and test it for me, he downloaded it and said that my game didn’t run on his cell phone.

It’s discouraging to make a game on a platform like this, 1 year wasted.

What have you done to debug the problem?

What devices you have tested on?

You need to provide more details, as otherwise it looks like low effort rant post.

Hello, today I’m going to test it, because this problem is not new, I’ve had it for months, it started with an error in the build, I kept changing the API, it started when there was that problem in API33 in unity. I’ve already made several posts here and sent them, I gave up creating games because of that, I’m coming back, I came back yesterday after 6 months without touching, due to the problems that happened. I don’t know if you can see my posts, these are my posts and the problems I had until I got to this problem of not wanting to install the game.

It all started here I can’t build my game https://discussions.unity.com/t/several-errors-unity-is-not-good- almost-giving-up-on-this-engine/931108

and continued here
I can't build my game

I don’t know how to explain the problem, but I remember that my solutions were to change the API in the settings, if I changed it a few times the game wouldn’t even build. Well, every problem is there in these posts, I gave up at that time due to the company’s lack of interest in solving problems, the unit only does lives flattering those who have already managed to sell the games.

Hello, send me the links to explain the problems you have until you get to this, I’ll try to solve it in Unity 6000, maybe it’s Unity, the problem started with an API error from what I read in the forums there was a theory that it was an incompatibility between the companies Unity and Google, Oracle, since my game had ads, an API, JDK and ad incompatibility, but I don’t know for sure, many at the time had this problem, since I have a tutorial channel, even on my YouTube people asked about this problem and I didn’t know, I didn’t follow to see if they solved these problems, I’ll go back to look into it today and find out if they solved it, in fact I asked the question to really find out if they solved the problem. I don’t know how to explain everything I did, I did a lot of things, I downloaded and downgraded Unity, I changed APIs, the build never managed to complete and when it finally completed the game didn’t run on cell phones. Everything is explained in the links I sent in response to another user
