title: Method 'GetArrayLength'/'GetByteArrayRegion' could not be resolved in JNI C file
body: <p>I'm getting the following error when trying to build my Eclipse Android project in one of my JNI C files.</p>
  
  <pre><code>Method 'GetArrayLength' could not be resolved
  Method 'GetByteArrayRegion' could not be resolved
  </code></pre>
  
  <p>I'm simply calling GetArrayLength/GetByteArrayRegion as follows:</p>
  
  <pre><code>jsize jsArruLen = (*env)-&gt;GetArrayLength(env,jDeviceListArr);
  (*env)-&gt;GetByteArrayRegion(env,jDeviceListArr, 0, jsArruLen, (jbyte *)(pszDrive));
  </code></pre>
  
  <p>Does anyone know what's wrong? The project builds successfully on another PC.</p>
  
  <p>Thanks.</p>
