title: reload map fragment by switching between two tabs
body: <p>I have three Activitys. One who organize the tab switching an two who shows a google map in a map fragment.</p>
  
  <p>If i switch between these two map activities i see both maps. The old one as a picture and the new one as map. for Example: I swicht from Activity A to Activity B, i see in Activity B the map from Activity B and a picture from the map in Activity A.</p>
  
  <p>If i minimize and maximize the application the Activity will be updated and so the picture from Activity A is removed. </p>
  
  <p>![Activity A][1]
  ![Activity B][2]</p>
  
  <p>How i can fix this problem?</p>
  
  <p>Thanks a lot</p>
