title: How to use recompiled OpenCV build for Android
body: <p>So I want to modify one of the files in the OpenCV build for Android and I followed the instructions on <a href="http://code.opencv.org/projects/opencv/wiki/Building_OpenCV4Android_from_trunk" rel="noreferrer" title="opencv">their site</a> to download the build and I was able to make it successfully. I modified one of the files (calibinit.cpp) and made it again and copied the files in the </p>
  
  <blockquote>
    <p>opencv/platforms/build_android_arm/lib/</p>
  </blockquote>
  
  <p>folder into the jniLibs folder of my AndroidStudio Project. </p>
  
  <p>However, the changes I made are definitely not working. I already had a previous OpenCV library linked to my project, so I'm pretty sure it's still using the old code. How do I use the new build with my AndroidStudio Project?</p>
