title: Does 'adb backup -apk' stores application private data?
body: <p>As can be seen at title, my question is it: does the command:</p>
  
  <pre><code>adb backup -apk -shared -all -f /home/me/my-device.bkp
  </code></pre>
  
  <p>Stores application private data? Such those at SharedPreferences; files stored at any context.getApplicationPrivateStorage() and databases created trough SQLiteOpenHelper?</p>
  
  <p>I'm willing to do that so I can throw my phone from a building :P</p>
