title: How to ask for the permission to become Default Video Player in Android?
body: <p>I am developing a video player app and I want my app to Prompt for the permission to be the default Video Player to be the <strong>default handler</strong> of video play.
  I know it has to be something like the default handler:</p>
  <pre><code>Intent setSmsAppIntent =
      new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
  setSmsAppIntent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME,
      getPackageName());
  startActivityForResult(setSmsAppIntent, your-result-code);`
  </code></pre>

  <p>But I don't know the Action I have to give to the Intent as action. Can someone please help me?
  Thanks in advance.</p>
