(2)c++

#include"JniHelper.h"

#include"platform/android/jni/JniHelper.h"

_org_play_test_ 包名、类名、方法名

extern "C" {
JNIEXPORT void JNICALL Java_org_play_test_CaddCall_retGooglePlay(JNIEnv* env,
        jobject thiz, jint pResult) {
    int aa = pResult;
    char buf[10];
    sprintf(buf, "%d", aa);
    std::string b = buf;
    CCMessageBox("12ss3", b.c_str());
}
