activity里有如下定义： 

 

public void cppCall_nonStatic_logsth(){  //非静态方法          Log.i("cppCall_nonStatic", "test2~~~~!!!");      }        public static Object cppCall_logsth(){  //静态方法          Log.i("cppCall", "test~~~~!!!");          return activity;      }

AppDelegate.cpp里： 

加上预定义（for android）

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)  #include 
      
         #include 
       
          #include 
        
             #if 1  #define  LOG_TAG    "JniHelper"  #define  LOGD(...)  __android_log_print(ANDROID_LOG_DEBUG,LOG_TAG,__VA_ARGS__)  #else  #define  LOGD(...)   #endif    #endif
        
       
      

关键代码片段： 

 

JniMethodInfo minfo;      jobject jobj;      bool b = JniHelper::getStaticMethodInfo(minfo,           "com/loy/puzzles/Puzzles",  //类路径          "cppCall_logsth",   //静态方法名          "()Ljava/lang/Object;");   //括号里的是参数，后面的是返回值。      if (!b) {          LOGD("JniHelper::getStaticMethodInfo error...");      }else{          jobj = minfo.env->CallStaticObjectMethod(minfo.classID, minfo.methodID);      }            JniHelper::getMethodInfo(minfo,          "com/loy/puzzles/Puzzles",           "cppCall_nonStatic_logsth",           "()V");      if(!b){          LOGD("JniHelper::getMethodInfo error...");      }else{          LOGD("ready to invoke method...");          minfo.env->CallVoidMethod(jobj, minfo.methodID);      }

 

最终LOGCAT打印日志如下： 

12-2 12:46:33.891: D/JniHelper(2008): testing~~~ 

12-2 12:46:33.891: I/cppCall(2008): test~~~~!!! 

12-2 12:46:33.891: D/JniHelper(2008): ready to invoke method...

12-2 12:46:33.891: D/JniHelper(2008): testing over~~~ 

即表示调用成功。
