body: <p>In my application there is a behavior that I don't understand. I have the <code>MainActivity</code> A as <code>SingleTask</code>.
  It calls an <code>Activity</code> B that is <code>SingleTask</code> too.
  When I press the <code>Home</code> button in the second activity to open another application, and after that I try to go to my application mantaining <code>Home</code> button pressed i always go to Main <code>Activity</code>, and I want second activity to be opened mantaining the state that had when i press <code>Home</code> button.</p>
