Rider Default IDE

I had this problem of Rider not being recognized after restarting Unity. I fixed by doing this:

Make sure both paths are created and with permissions

Edit -> Preferences -> Package Manager

/home/<user>/.config/unity3d/cache
/home/<user>/.local/share/unity3d

Android SDK

My .zshrc:

export JAVA_HOME=/home/<user>/Unity/Hub/Editor/2022.3.40f1/Editor/Data/PlaybackEngines/AndroidPlayer/SDK
export PATH=$JAVA_HOME/bin:$PATH

which java should point to the same sdk above. Fedora comes with a builtin java that needs the symlimk to be replaced or removed

/usr/bin/java -> /home/<user>/Unity/Hub/Editor/2022.3.40f1/Editor/Data/PlaybackEngines/AndroidPlayer/OpenJDK/bin/java
