title: Android: no difference found between an apk file signed for release and for debug
body: <p>I have just built for release my first Android App. I signed it with a key using keytool.exe.</p>
  
  <p>Then, I did the following. I uploaded to a website both files, the apk signed for release and the apk signed for debug. </p>
  
  <p>Then, with my Android device I entered the website and clicked on the two file links. They both behaived equally. The files where downloaded in the same way. And I could install both by clicking on them once they were in the 'download' folder.</p>
  
  <p>I expected some differences. For instance, the device automatically installing the release version when clicking directly from the website.</p>
  
  <p>What are suposed to be the differences between a release and a debug apk file?</p>
  
  <p>Thanks.</p>
