Unparsed aapt error

So you played too much with your xml, and now you get a stupid "Unparsed aapt error" that blocks you from running your app.

Don't panic like I did.

1) Delete that error message.
2) Run your app again.
3) If you encounter a "Could not find [app name].apk", just make some lame change in your code or xml then run the app again.
