title: Android Device Chooser Shows Red X In Target Column
body: <p>I've recently built an Android app with a minSdkVersion of 7 and targetSdkVersion of 10.  I'm now making the app tablet compatible and adding action bars.  So I updated by targetSdkVersion to 15 and in my project properties, moved my Project Build Tarket to Android 4.0.3, API 15.  I also double-checked that my Java Compiler is 1.6.</p>
  
  <p>Without making any other changes to my code, I try to run my app and in the Android Device Chooser, my two physical devices, versions 2.3.4 and 3.1, both have a red X in the Target column, instead of the green check mark.</p>
  
  <p>I'm also working with the ActionbarCompat sample app and a sample app from ActionbarSherlock and when I run one of those apps, both of my devices, show a green check mark.  Both of these sample apps have their Project Build Target set to 4.0.3 and the same sdkVersion settings that I have in my app.  As far as I can tell, my app is setup the same as the others.  Why does my app then have a red X next to my device versions in the Target column.</p>
  
  <p>Thanks!</p>
