参考珊瑚SDK,jni的调用方式

extern "C" { #if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)     void Java_com_friendou_Interface_coralsdk_SendtoGame(JNIEnv *env, jobject thiz, jstring info)     {         const char *temp = env->GetStringUTFChars(info, NULL);         if (gSDKCallback == NULL || p != NULL)         {             __android_log_print(ANDROID_LOG_INFO,"SDKCallbackError","The gSDKCallback pointer is null !");             return;         }         FMJSONDictionary *Recivejson = new FMJSONDictionary();         Recivejson->initWithDescription(temp);//         __android_log_print(ANDROID_LOG_INFO,"SDKCallback","SDKCallback message = %s", temp);         const char *ReciveAction = Recivejson->getItemStringFMValue("action");         if (strcmp(ReciveAction, "1001") == 0)         {             char const *userlist = Recivejson->getItemStringFMValue("userlist");             __android_log_print(ANDROID_LOG_INFO,"Test","userlist = %s", userlist);             GameUserSelectedNotification(userlist);//userlist tReturn.c_str()                     }         else if (strcmp(ReciveAction, "1002") == 0)         { //            char const *userlist = Recivejson->getItemStringFMValue("userlist"); //            GameReplayNotification(userlist);         }         else if (strcmp(ReciveAction, "1003") == 0)         {                 __android_log_print(ANDROID_LOG_INFO,"Test","LogoutNotify1003");             LogoutNotify();         }         else if (strcmp(ReciveAction, "1004") == 0)         {             bool isOn = Recivejson->getItemBoolFMvalue("isOn",false);             MusicTurnOffAndOn(isOn);         }         else if (strcmp(ReciveAction, "1005") == 0)         {             bool isOn = Recivejson->getItemBoolFMvalue("isOn",false);             SoundTurnOffAndOn(isOn);         }         else if (strcmp(ReciveAction, "1006") == 0)         {             int aisLogin = Recivejson->getItemIntFMValue("isLogin",0);             LoginResult(aisLogin);             __android_log_print(ANDROID_LOG_INFO,"Test","LoginResult 1006 = %d", aisLogin);         }         else if (strcmp(ReciveAction, "1007") == 0)         {             __android_log_print(ANDROID_LOG_INFO,"Test","GameBackNotification   1007");             GameBackNotification();         }         else if (strcmp(ReciveAction, "1008") == 0)         { //            ApplicationWillResignActive();         }         else         {             __android_log_print(ANDROID_LOG_INFO,"SDKCallbackError","Have no this callback !");             return;         }     } #endif }

珊瑚SDK官方调用例子，可以下载来看看哦，对于Android开发接入jni还是有很大的帮助
