There was an error while saving the standalone application

Runtime (class file version 55) this version of the Java Runtime only recognizes

The release of LiveCode 10.0.3 (rc 1) no longer requires java version 8. In fact, it no longer allows it.

You now only require a minimum version of Java 11, and you can use the latest versions of Java and Build Tools.

So, you will need to remove Java 8 and install at least Java version 11.

Additionally, I used Android studio to (mine is the Meerkat version) open the SDK manager window (Under the "Tools" menu --> "SDK Manager") and (under the SDK Platforms tab) install Android 15 SDK 35 then (under the SDK Tools tab) install Android SDK Build-Tools 35. (I have no idea if that Build-Tool version is required but it worked for me.) I installed a few other things but I suspect those weren't necessary to the LiveCode build.

I'm using a Mac. I found the directions online for removing the Java 8 version to be surprisingly unhelpful. While there were plenty of command line bits, none of them seemed to address the location of the main jdk on my machine. (Though some YouTube videos did.) I knew the location of mine:

Code: Select all

/Library/Java/JavaVirtualMachines/jdk-1.8.jdk

and eventually just threw the jdk folders in the trash. But I was surprised that the Oracle Java installer didn't also have an uninstaller. (Okay, I found a Java uninstaller but it didn't work )
