title: How to return from Unity Player to previous running Android Activity?
body: <p>I have the same problem as mentioned in this topic <a href="https://stackoverflow.com/questions/7754373/integrating-unity-with-eclipse-back-button-click">Integrating Unity with Eclipse: Back Button Click</a> but the suggested solutions didn't work.</p>
  
  <p>I have a Unity Player embedded in a Native Android Application. I can start the Unity Player without a problem but now I want to go back to my previous activity with the back button. I already tried Application.Quit from Unity side and finish() from android side, both closes the whole application. I also tried to start a new Activity from the Unity context but this doesn't work either, I think this is because I work with fragments. My Activity setup is as follows:</p>
  
  <p>MainActivity where several fragments are embedded. Two of them contain Lists from which I can start a new Activity which shows me detail views of the List elements. The detail views are also fragments in which you can swipe left and right to previous/next element (similar to gmail app). From within the detail view, you can start Unity to have some augmentations with the qualcomm vuforia framework.</p>
  
  <p>up to this point everything works, but I can not go back from the UnityPlayer to the details view.</p>
  
  <p>Does anyone have any idea how to achieve this?</p>
  
  <p>Thanks!</p>
