Hello,

I understand there is some error while trying to configure MATLAB to work with android studio.

The error message “Unsupported class file major version 65” suggests that the issue may lie with the compatibility of Gradle with the Java version. If possible, update Gradle to a version that supports the Java version you are using. You can do this by modifying the "gradle-wrapper.properties" file in your project:

distributionUrl=https\://services.gradle.org/distributions/gradle-version-bin.zip

Replace version with latest Gradle version.

Alternatively, switching to a compatible Java version may also resolve the issue.

Hope this helps!

I got this problem because I was using a too new version of Android Studio (2024 and JDK 21) vs. what MATLAB expects (2022 and JDK 17)

You can switch JDK by editing the file SupportPackages/R2024b/toolbox/target/supportpackages/android/template/AndroidBuild/gradle.properties. On my Linux machine SupportPackages is found in ~/Documents/MATLAB.

I commented out the java.home=${JavaHome} line and replaced it with a JDK downloaded using Android Studio:
