Errors build app bundle for google play

Hi everyone, I am trying to publish my game on google play but I have this error.

"Your app's current target API level is 28, but the minimum target API level must be 30 to ensure that your app is based on the latest APIs that are optimized for security and good performance. Change your target API level. app with at least 30 "

To try to solve the problem, I downloaded the API 30 via Android Studio and copied the affected folder to the path C: \ Program Files \ Unity \ Hub \ Editor \ 2020.1.3f1 \ Editor \ Data \ PlaybackEngines \ AndroidPlayer \ SDK

((Basically I copied the API folders from the path
"C: \ Users \ User \ AppData \ Local \ Android \ Sdk \ platforms"

to the unity path
"C: \ Program Files \ Unity \ Hub \ Editor \ 2020.1.3f1 \ Editor \ Data \ PlaybackEngines \ AndroidPlayer \ SDK \ platforms "

But now I think I've done some damage, because if I was able to build before now I can't do it anymore because Unity gives me a lot of errors, now I show them to you..

These are the unity errors:

The only way that seems to work consistently for Android SDK updates is to REMOVE ALL SDKs first, using whatever method you like, then install only the one you want, along with its tools.

Once that's good, go tell Unity about it in the usual place(s).

 

So should I delete the folders I don't need from the path:

"C: \ Program Files \ Unity \ Hub \ Editor \ 2020.1.3f1 \ Editor \ Data \ PlaybackEngines \ AndroidPlayer \ SDK \ platforms "
and leave only the one I need?

 

The folder you list above appears to be what comes with Unity... Are you sure that's the installed SDK??! I don't think so... usually it goes in

.android

folder or elsewhere. The above is usually just the source.

I'm just saying, outside of Unity, pretend you're just a vanilla Android developer: uninstall all your old SDKs before upgrading to a new one when working with Android, that's all.
