I'm using the most recent Android Studio and today my Mac crashed. After rebooting, I opened Android Studio and now all of my projects are erroring out with the Android URI not being found. They won't build, won't make, nothing. If I create a new Project, Android project is not one of my options, just all the rest of the options. Is there anything I can do besides remove and reinstall?
I'd recommend you do a uninstall of Android Studio and then do a clean install. It might be that there are corrupted or locked system files that are causing the issue. Make sure you backup your Android projects onto a USB first - just in case.
