  <p>Where at CameraActivity.java:30 is:</p>
  
  <pre><code>static { System.loadLibrary("libiconv.so"); }
  </code></pre>
  
  <p>I have also tried</p>
  
  <pre><code>static { System.loadLibrary("iconv"); }
  </code></pre>
  
  <p>Is it some thing to do with gradle configuration, as I am new to Android Studio, or the error source is something else?</p>
