title: Android: Temporarily disable orientation changes in an Activity
body: <p>My main activity has some code that makes some database changes that should not be interrupted. I'm doing the heavy lifting in another thread, and using a progress dialog which I set as non-cancellable. However, I noticed that if I rotate my phone it restarts the activity which is REALLY bad for the process that was running, and I get a Force Close. </p>
  
  <p>What I want to do is programatically disable screen orientation changes until my process completes, at which time orientation changes are enabled.</p>
