title: How to lock fragment orientation without locking activity orientation?
body: <p>I have a specific use case where I want a fragment to be locked in portrait mode, but still rotate the activity (and/or other fragments visible in the same activity). Is it possible to do that?</p>
  
  <p>All the solutions to locking a fragment orientation suggest to use setRequestedOrientation and lock the activity orientation, but I need other visible fragments to rotate.</p>
  
  <p>My app supports API 10+ (if there is a nice solution that uses API 11+ I may consider removing support for landscape in API &lt;11).</p>
  
  <p>Thanks in advance.</p>
