title: Best way to store intrinsic camera parameters on Android
body: <p>I am having some troubles saving the camera intrinsics to the sd card.
  The camera calibration is working, but I need to store the intrinsics to the sd card and load them back when the app restarts. 
  This is a problem for me, can someone help me and provide me some information about how to store the intrinics, as the save xml stuff from openCV seems not to be available on android.</p>
  
  <p>Thanks</p>
  
  <p>PS my intrinsics are store in a Mat</p>
