The top two suggestions at this SO didn't help (and when using the path mentioned farther below, the emulator wouldn't start and gave a Mac alert error). Please check that /Library/Internet Plug-Ins/ugin/Contents/Home contains a valid JDK installation. (There was another download page, but it required an Oracle login.)Īfter installing, I then got the error (when building): Could not find tools.jar. So do I just not think about how it disappeared, and go ahead and just install the JRE or JDK from Oracle? Or is there a way to tell the Mac to 'please fix this'? I only do Flutter development on the Mac. I also don't surf the web or download/install stuff on my Mac.

why am I even here? Where did my Java go? I went to Oracle, but they mention about costs. But typing java -version or /usr/bin/java -version gives that same error. When I type which java or which javac they both point to /usr/bin/java and /usr/bin/javac. But I've BEEN building to Android, so I'm completely confused why today it all of a sudden can't find Java. I also tried a different project via Android Studio, and it says the same thing. Please visit for information on installing Java.

But there is no Java icon in my System Preferences. Research says to check the Java icon in the System Preferences. I've been building to 3 different Android devices (1 emulator 2 devices (one USB one wireless)) since I got my MBP (came with Big Sur) a couple months ago. All of a sudden I cannot build to Android. I run Flutter in VS Code, and have been having no issues until today.
