So, now that I want to test my game on Android, I switched the platform from Windows to Android, but I had to download the required Android Files, which I did through the unity hub, now every time I try to build the game I get 4 errors, is there a conflict about SDKs and JDKs ?
It seems unity can’t build the .APK file in order to install the game on my phone for testing, what is going wrong here ?
How to troubleshoot build failures:
First, make a blank project with a single blank scene and prove that it builds successfully.
If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.
Until you can build a blank project to the target platform, don’t fiddle with anything else.
Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.
Most often things that prevent building are third-party libraries such as Firebase.
Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.
It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.
Android build not building:
Recently (circa July 2022) there have been reports of Unity’s installer failing to install the Android Tools.
Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022 (edited on August 23, 2023 to include Android SDK 33…):
Android Gradle errors and other related stuff:
That doesn’t mean it’s a post for the 2D forum but a post for the Android forum.
I’ll move your post.

Many thanks !
Small problem tho, the resolution doesn’t match, like the UI is not set for the Android screen resolution ?
It seems that the UI doesn’t scale with the resolution…how to fix that ?
The sad fact is that some versions compile for Android while others give persistent errors. I have found recently that 2022.3.11 and 2022.3.20 seem to work better than other versions for Android.
