title: After update the APK supports fewer devices than previously
body: <p>I have a relative simple App that was already in the Play-Store of Google.</p>
  
  <p>Now I've made an Update of this App. 
  One Point of this Update was that I include the ZBar-Scanner. The Rest of the changes were minimal and shouldn't have any influence on my problem.</p>
  
  <p>I just put the newest verison of my App in the Play-Store and I get following warning:
  "Warning: Active APKs support fewer devices than previously active APKs. Some users will not receive updates."</p>
  
  <p>I've downloaded ZBarAndroidSDK-0.2.zip from sourceforge.net (http://sourceforge.net/projects/zbar/files/AndroidSDK/) and import it to my project as it is explained in the README-File.</p>
  
  <p>I tested my App local on my HTC Wildfire S (->Version 2.3.5), on Samsung Galaxy 3 (GT-I5800 -> Version 2.2) and on my Galaxy Nexus (-> Version 4.2). There was never a Problem. Everything worked.
  I also tested the exported APK and had no Problems.</p>
  
  <p>Now I add this APK to the Play-Store and updated my App and I get the warning for the tested devices. Neither my HTC Wildfire, nor my Samsung Galaxy 3 can update the new version. </p>
  
  <p>Can anybody help me and explain me whats the Problem?</p>
  
  <p>Thanks a lot!!!</p>
