I installed JDK in Android studio, seems it’s installed in ~/Library/Android/sdk/sources/android-28

Setting export JAVA_HOME=/Users/mrgloom/Library/Android/sdk/sources/android-28/ or export JAVA_HOME=/Users/mrgloom/Library/Android/sdk produce error like:

ERROR: JAVA_HOME is set to an invalid directory: /Users/mrgloom/Library/Android/sdk/sources/android-28/

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

    Using JDK shipped with Android Studio and setting export JAVA_HOME=/Applications/Android Studio.app/Contents/jre/Contents/Home helped me.

    Might need to clear caches and restart the studio. These steps worked for me –

    1. Set Java home. You can use embedded JDK in Android Studio.

    export JAVA_HOME=/Applications/Android Studio.app/Contents/jre/Contents/Home.

    Use Setting Java Home in MAC for reference if required.

    1. Close terminal
    2. Invalidate Caches & restart – Include ‘Clear file system cache and local history’
