title: Must I specify the parent activity name in the Android Manifest?
body: <p>I have an activity that starts another activity.<br>
  Is it mandatory that I specify the parent activity in the Android Manifest?
  Im asking this because there might be other activities that will start this one as well, so should I specify all of them?</p>
  
  <pre><code>android:parentActivityName="com.example.myfirstapp.MainActivity" 
  </code></pre>
