title: Huge apk filesize when using OpenCV
body: <p>I am building a prototype app with OpenCV. The app currently does not do anything but its apk file size is 6MB. The size is 10 times of normal app size. Is there any way to reduce this size? </p>
  
  <p><strong>Update:</strong> I found out that as long as I use android native camera and interface with OpenCV in JNI/C++, the file size can be dependent on the methods you are using in the library. Current my test app with simple filter has size of 700K.</p>
