title: How does eclipse install apk files on devices? I get an parsing error when I do it manually
body: <p>When running my app from eclipse with my device plugged it, the app runs just fine. Everything seems perfect. So I decided to export and sign my app, then email the apk to myself via gmail. After downloading the apk on my device, I get an error saying "There is a problem parsing the package".</p>
  
  <p>I have uninstalled all previous versions of the app, and authorized the phone to download apps outside of the google play store. </p>
  
  <p>I was just wondering how eclipse was able to install the app on my phone fine. </p>
  
  <p>Thanks.</p>
