JDK directory is not set or invalid (unity)?

Question

I am now creating a keystore for my game (in unity) but when I press the add key button, an error pops up

Java Development Kit (JDK) directory is not set or invalid. Please, fix it in Preferences -> External Tools UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr) (at /Users/builduser/buildslave/unity/build/Modules/IMGUI/GUIUtility.cs:187)

I installed the JDK and checked the path of it in the terminal using the command /usr/libexec/java_home, then it shows me that the path of the JDK is /Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home.

I copy and paste it in the JDK path in unity but the error still pops up. I actually checked the JavaVirtualMachines in my computer's library but there's nothing in it.

How can I solve this problem? Any help is greatly appreciated.

Answer 1

Actually I solve this problem by adding the modules (Android SDK & NDK Tools, OpenJDK) to my Unity Editor. Actually if you tick the Android build support module, it won't automatically help you to tick the two modules above.
