title: When should I define my Android app as not movable to SD card (installLocation=internalOnly)?
body: <p>In which cases I should forbid the users to move my app to the SD Card (by setting <a href="http://developer.android.com/guide/topics/manifest/manifest-element.html#install" rel="noreferrer"><code>installLocation</code></a> to <code>internalOnly</code>)?</p>
  
  <p>I'm asking to know this for a few apps, so please don't ask about my app. I want to know this in general for any app.</p>
