I'm trying to call the method StringBuffer append(String) in the JNI native method, but I couldn't retrieve the append(String)'s method, what's wrong with my code below :
(sbcls is the StringBuffer's class id)
I could use the above pEnv,sbcls to retrieve the void setLength(int)'s methods ID, but it just don't work on StringBuffer append(String), why ? help please!!
