title: Computer Vision and AR libraries availabe for Android?
body: <p>I am starting out as an Android Developer, and I would like to know if there are any Computer vision libraries or Augmented Reality libraries for the Android SDK, as I am planning to use these libraries for a mobile app.</p>
  
  <p>I have read that if I download the NDK, I might be able to "import/use" the C openCV, and ARtoolkit libraries, but I am wondering if this is possible, or if there is a better and easier way of using these tools.</p>
  
  <p>Android apps are programmed in Java, yet OpenCV &amp; ARtoolkit use C/C++. Is there any way to use these libraries?</p>
