title: Android App runs in emulator but says "Not Installed"
body: <p>I can run my app and do things fine on the emulator in Eclipse.  When I go "Home" in the emulator and try to run the App again (by clicking its icon in the Apps folder) it says "App isn't installed"</p>
  
  <p>EDIT: Also I am not being prompted to give permissions on the device itself (emulator or Nexus 7)</p>
  
  <p>Also, when I export the apk to a real device (nexus 7 running 4.2.1) the app does not run and it indicates it is not installed.  Any thoughts?</p>
  
  <p>Here is the manifest:</p>
