我正在从我的 jni 类中调用一个非静态函数,但我的游戏得到了
NoSuchMethodError
我已经给出了以下功能
jni类
void InitializeJni()
{
cocos2d::JniMethodInfo methodInfo;
if (! JniHelper::getStaticMethodInfo(methodInfo, CLASS_NAME, "Start", "()V"))
{
return ;
}
methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID);
methodInfo.env->DeleteLocalRef(methodInfo.classID);
}
JNIEXPORT void JNICALL Java_com_games_Game_MyClass_nativeObjectCallBack(JNIEnv *env, jobject obj)
{
jclass cls = env->GetObjectClass(obj);
jmethodID mid = env->GetMethodID(cls, "Init", "()V");
if (mid == 0)
return;
env->CallVoidMethod(obj, mid);
Java 类
public static native void nativeObjectCallBack();
public void Init()
{
//my code
}
public static void Start()
{
((CYWGameAndroid)CYWUtil.GetInstance().GetContext()).runOnUiThread(new Runnable()
{
@Override
public void run()
{
nativeObjectCallBack();
}
});
}
谁能告诉我为什么会这样
这是我的 logcat 输出
