title: Android NDK java.lang.UnsatisfiedLinkError: findLibrary returned null
body: <p>Having the above error in your Android JNI app?  Read on...</p>
  
  <p>Up front, I'll say that I've already solved this, in my own way, but I feel something in the Android build system (perhaps regarding Eclipse) is broke, and I hope to save someone else hours of pain.  Perhaps others have come across this issue and can comment on what worked for them.</p>
  
  <p>For a while, I've had an Android project with some JNI code that I developed using the NDK.  Then, today, I changed something in the java code and then poof, I could no longer load my JNI library.  It failed with an exception like:</p>
  
  <blockquote>
    <p>E/AndroidRuntime(  999): java.lang.UnsatisfiedLinkError: Couldn't load mylibrary: findLibrary returned null</p>
  </blockquote>
  
  <p>I googled and tried everything (rebuilding, close and relaunch Eclipse, etc, etc)</p>
  
  <p>What finally fixed my problem?  I physically uninstalled my app from the device before trying another run.  That's it.  After that, it worked.  What worked for you?</p>
