Android Build Error in Unity 2020.3.3f1

Unity Engine

Hi all,

I upgrade my existing project to Unity 2020.3.3f1 and I get a build failure when trying to make the build. I didn’t have this in Unity 2019.2. I’m not really familiar with Android stuff so I’m not sure how to fix it. For SDK / NDK / JDK, I have the preferences set to using default Unity versions. I have minimum API set to 24 and Target API set to Highest Installed.

I don’t really know much about Android so the error message is greek to me. Can anyone provide any guidance? Much appreciated,

Quick update, I was able to get past this enabling R8 and Release on my Minify settings:

Can I confirm that Release is the right option for submitting the final version of the game to the play store?

You should use the 2019 version

The same in 2020.3.11f1
Does anyone know and can explain the cause of it? Please :frowning:

Okey. Here is the workaround:
Restart Unity. If restarting will not solve the problem, try to cleanup project’s Library folder before starting Unity.
In fact, we have to restart Unity every time when add or update (build new version) some java lib :eyes:
Debugging becomes painful for me.

Can someone suggest something smarter, please?

Enabling R8 and Release on Minify don’t work for me, because it breaks AndroidJavaObject calls.

For me I reinstalled unity 2020.3, this time I made sure to check Android SDK, NDK and Open JDK.
