Hello, I wanted to add Unity Ads (Advertisement Legacy) to my project. It still builds fine and everything, but like every 5 mins I get error that I need to install OpenJDK. It is really annoying. This did not happen before I installed Advertising package. Also, sometimes android resolver pops up but does nothing. I also had issues before with something called android gradle (I was not able to do notifications). I tried deleting and reinstalling JDK and SDK and so from unity hub, but it deos not detect that I deleted them (I have restored them from bin now). That oracle site is also outdated.

Edit: I have a button in my scene that should load an ad in build, but nothing happens (Rest of app is fine)

Check what’s your JAVA_HOME, and see if it’s the same as the one that Unity is using.

  1. Open Command-line prompt
  2. Run:
echo %JAVA_HOME%

bruh…
I think that means that Java home is not defined? Think that could be the issue?

btw, this is the warning I keep getting:

My recommendation would be to first try to update Unity to the latest LTS version available. Currently it’s 2022.3.44f1 (download link), that might solve the issue.

How to Set the JAVA_HOME Environment Variable in Windows

  1. Open System Properties:

    • Press Win + X and select “System”.
    • In the “System” window, click on “Advanced system settings” on the left side.
    • In the “System Properties” window, click on the “Environment Variables” button.

  2. Set JAVA_HOME Variable:

    • In the “Environment Variables” window, under the “System variables” section, click “New…”.
    • For the “Variable name”, enter:
      JAVA_HOME
    • For the “Variable value”, enter your OpenJDK path from the External Tools Unity window:
      C:\Program Files\Unity\Hub\Editor\2022.3.17f1\Editor\Data\PlaybackEngines\AndroidPlayer\OpenJDK
    • Click “OK” to save the new variable.

  3. Update the Path Variable (Optional but Recommended):

    • In the same “Environment Variables” window, find the “Path” variable under “System variables”, select it, and click “Edit…”.
    • Click “New” and add the following path:
      %JAVA_HOME%\bin
    • Click “OK” to save and close all windows.

  4. Verify the Setup:

    • Open a new Command Prompt and type:
      echo %JAVA_HOME%
    • This should return the path you set.
    • To verify that java is recognized, type:
      java -version
    • It should display the version of Java located in the specified directory.

This setup ensures that JAVA_HOME is permanently set and available to all programs that require it.

OK, I have tried setting JAVA_HOME variable, now I get a different error/warning:

I think that’s the same issue I have: When I run java -version in cmd, I get no response

I have now installed new Unity Editor. How do I upgrade to the new version? Do I need to copy all files over to a new project in new editor? Do I need to delete old editor?

Just open the same project with the new Editor. A popup dialgo should appear asking for permission to automatically upgrade the project.

29

I don’t know what to do anymore…
