title: Android manifest file breaks after adding a permission
body: <p>I have a really strange problem with an Android project I inherited.  I tried adding a permission to it and suddenly a few other permissions break with the red "X" being displayed along with this error:</p>
  
  <p>"Permission is only granted to system apps."</p>
  
  <p>How could this be if all I did was add a permission?  If I don't save the manifest and clean the project, all the red "X" marks go away and it compiles again.  Why is this happening?</p>
