Before AS was refusing to install the APK onto the Glass so I uninstalled it, deleted all the files, and reinstalled AS using the installer file downloaded from the website. I downloaded and updated all the APIs I need and now it is coming up with one of two errors:
IDE internal error occurred
Failed to set up Android modules in project 'My Application'
or
Error:Module 'app': platform 'Google Inc.:Glass Development Kit Preview:19' not found.
This is happening on both my desktop and my laptop(which I didn't reinstall AS on). There doesn't seem to be any pattern to these errors and I don't know what to do, each error I fix just uncovers another error.
