JAVA_HOME: does not contain java which is required to process Android libraries

Hello, I am trying to make an Android build of my game, but my editor does not read the Android module that I installed for it. Im using 3.9f1, but appears to be loading something from 3.0b6 in the error message.

Error Message on loading a project:
JAVA_HOME environment references a directory (C:/ProgramFiles/Unity/Hub/Editor/2019.3.0b6/Editor/Data/PlaybackEngines/AndroidPlayer\OpenJDK)
that does not contain java which is required to process Android libraries

Things Ive tried
- Completely reinstalling 3.9f1 engine with the Android module
- Set my Environment Variables. Variable name: JAVA_HOME Variable value: C:\Program Files\Java\jdk-14.0.1
- Deleting the AndroidPlayer folder inside PlaybackEngines folder and manually download the Android module and install it

After reinstalling the engine or Android module it still stays "You are missing the recommended JDK. Install the recommended version using Unity Hub."

I've made android builds in the past with no problems but I appear to be missing something here.

 

Did you install Android Build Support from Unity Hub? Unity most likely expects a specific version of Java to be there, which you can get via Unity Hub.

You can find this in Installs -> <your unity version> -> click the "..." menu -> Add Modules -> Android Build Support

You should install all of it but there is specifically OpenJDK under there too.

 

Thanks for the reply. Yes, I have Android Build Support, Android SDK & NDK Tools and Open JDK all listed as Installed

 

I think Unity might use a special "builder" user. That user will have different environment variables set than your user. This doesn't solve your problem but it might explain why JAVA_HOME would be different even if you set JAVA_HOME yourself. I think it's supposed to set JAVA_HOME when you pick your JDK in Android build settings.

 

Sorry! I have the same issue but I don't understand how you solved this problem.

 

Have same issue with Unity 2020.3.0f1 on Mac X OS. Even SDK point to right directory I'm getting

JAVA_HOME environment references a directory (/Applications/Unity/Hub/Editor/2019.4.15f1/PlaybackEngines/AndroidPlayer/OpenJDK) that does not contain java which is required to process Android libraries.

As I understand that path was set automatically when I was installing Unity 2019. But currently I removed that version.
Also would be worth to mention that I installed the Unity 2020.3.0f1 from installer not Unity Hub, since it wasn't working from there.
This error I started getting after installing Facebook SDK.
I tried this https://stackoverflow.com/questions...environment-references-a-directory-in-unity3d as well but was unsuccessful.

 

I am also facing same problem after installing Facebook SDK. Tried unchecking and rechecking the android SDK and JDK checks from Preferences of Unity, but find no luck.

 

I was able to fix by going into preferences, copying the (correct) pre-generated paths for all the materials, and pasting them into the fields after disabling the 'installed with Unity' checkboxes. Automated service resolution keeps looking for a directory that doesn't match the project version and didn't exist anymore.

I think my case was triggered by upgrading the project and deleting the previous unity version. The path resolution code is stuck looking for 2018 even though everything in the editor window looks correct. I believe the project started in 2018 so perhaps some value in the code got stuck on it?

 

thanks a lot for your solution, it works well.
