title: Can't compile app after adding activity
body: <p>My app was compiling fine and running without problem. I then went to add a new activity using the File > New > Other...</p>
  
  <p>I normally never add activities using this tool as I have been weary in the past that it actually causes more damage to my app than its worth. But today, I yielded to my urge to give it another try instead of just copying and pasting an existing activity. And sure enough, the same BS happened as I feared. It messed up my app and now I cannot compile it. Rule #1: stay away from these shit tools that Google delivers. Do EVERYTHING from hand. I tried doing a clean multiple times and even deleted the bin and gen folders but of no avail. Here is what the error window is reporting:</p>
