title: It seems that your device does not support camera(or it is locked)
body: <p><code>Android opencv</code> samples and tutorials were running fine and suddenly one day I get this for all of those:<br>
  <code>"It seems that your device does not support camera (or it is locked). The application will be closed"</code><br>
  Please help, how to I can fix it?</p>
  
  <p>I have reinstalled opencv and imported again and made new emulators but the problem still persists.</p>
