I updated android studio to Electric El, but after updating, it is unable to find Java Runtime.

Flutter doctor gives this error and the code does not compile.

In your zshrc file add.

export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jbr/Contents/Home

Restart the android studio. Flutter doctor will give this.

You can ignore the warning ✗ Unable to find bundled Java version. but the code will compile successfully.

Open the folder where Android Studio is installed.

In most cases, it is "C:\Program Files\Android\Android Studio"

1. Open the "jbr" folder inside the Android Studio folder ("C:\Program Files\Android\Android Studio\jbr"), and copy all contents in it.
2. Then go back and create a new folder called "jre" -> "C:\Program Files\Android\Android Studio\jre"
3. Paste all contents which you copied from "jbr" folder to "jre" folder.
4. Click Start and search for "Environment" and open "Edit the Environment variables" from search result.
5. Click to open "Environment variables"
6. On "User variables" pane click new and add new variable with name "JAVA_HOME" and path "C:\Program Files\Android\Android Studio\jre". Click OK to save.
7. Restart Android Studio and run flutter doctor. It will solve the problem.
