无法从JNI

Question

与ArrayList对象调用Java API

我试图调用接受字符串ArraList从JNI

/*My Java Method that needs to be called from JNI*/ 

public void postArrayListOfStringsToJavaFromJNI(ArrayList<String> list) 
{ 
} 

//I am trying to create the methodId like below in JNI to call my Java API postArrayListOfStringsToJavaFromJNI 

jmethodID method_id = env->GetMethodID(dmrcallbacks, "postArrayListOfStringsToJavaFromJNI", "(Ljava/lang/Object;)V"); 

一个Java API，但我得到一个错误

11-22 23:22:45.130: E/AndroidRuntime(19189): java.lang.NoSuchMethodError: no method with name='postArrayListOfStringsToJavaFromJNI' signature='(Ljava/lang/Object;)V' in class Lcom/example/JavaSample; 

有作为调用具有参数“ArrayList”的Java API的第一参数的具有“（Ljava/lang/Object;）V”的GetMethodID调用的任何问题

Answer 1

(Ljava/lang/Object;)V是void方法采用java.lang.Object类型的单个参数，您可能需要使用(Ljava/util/ArrayList;)V。
