title: What determines how long an app takes to install? Android
body: <p>I'm using eclipse and am currently working on an android app. When I first started developing, after the upload through ADB finished, the app would install and start almost instantly, now it is taking a consistent 12 seconds. 
  I was wondering about what determines the time it takes for an app to install on a device once it has been uploaded?</p>
  
  <p>Edit: Just tested this on 3 different android devices, all 3 take exactly 12 seconds.
  My apk file size is 378kb.</p>
