title: jni signature for method
body: <p>My java method contains a function </p>
  
  <pre><code> public static void downLoadProfileImage(String url, String fileName,  int tag, int from)
  </code></pre>
  
  <p>I am getting a JNI signature error:</p>
  
  <pre><code>if (JniHelper::getStaticMethodInfo(jniMethodInfo, packageName.c_str(), "downLoadProfileImage", "(Ljava/lang/String;Ljava/lang/String;I;I;)V")) 
  </code></pre>
  
  <p>If I just keep the two strings, everything works. But with two integers it throws an error? What am I doing wrong?</p>
