title: Retain Fragment state between Activities
body: <p>Its possible to retain a <code>Fragment</code> between Activities?</p>
  
  <p>Lets say I have Activity <code>A</code> with Fragment <code>F_Left</code> placed at the left and Fragment <code>F_Right</code> placed at the right. If I want to launch a new Activity and keep Fragment <code>F_Left</code>... how can I do it?</p>
  
  <p>Can I retain Fragment <code>F_Left</code> state between activities?</p>
  
  <p>Note that I want to launch a new Activity because Fragment <code>F_Left</code> is my app menu and Fragment <code>F_Right</code> changes completely the context of the user operations... and my app have many of operations, so it makes sense to have an Activity per operation.</p>
  
  <p>I know its possible to retain <code>Fragment</code> within an <code>Activity</code>, but as <code>Fragment</code> life cycle is closely tied to the container <code>Activity</code> I don't know if this is possible keep <code>Fragment</code> state between Activities.</p>
