Question

我有以下功能：

JNIEXPORT void Java_com_vidyo_vidyomod_services_VidyoCommands_Login(JNIEnv* env, jobject javaThis,
                                                                jstring vidyoportalName, jstring userName, jstring passwordName, jobject callback) {

FUNCTION_ENTRY;
const char *portalC = (*env)->GetStringUTFChars(env, vidyoportalName, NULL);
const char *usernameC = (*env)->GetStringUTFChars(env, userName, NULL);
const char *passwordC = (*env)->GetStringUTFChars(env, passwordName, NULL);
jclass loginClass = (*env)->GetObjectClass(env, callback);
VIDYO_CLIENT_LOG_INFO_FORMATTED("Login() NDKMETHOD1 Starting Login Process BEFORE %d" , loginClass);
methodClass = (*env)->GetMethodID(env, loginClass,  "onResponse", "(Ljava/lang/String;Ljava/lang/String;)V");
VIDYO_CLIENT_LOG_INFO_FORMATTED("Login() NDKMETHOD1 Starting Login Process BEFORE 2%d" , methodClass);

VIDYO_CLIENT_LOG_INFO("Login() NDKMETHOD Starting Login Process");
VidyoClientInEventLogIn event = {0};

strlcpy(event.portalUri, portalC, sizeof(event.portalUri));
strlcpy(event.userName, usernameC, sizeof(event.userName));
strlcpy(event.userPass, passwordC, sizeof(event.userPass));

VIDYO_CLIENT_LOG_INFO_FORMATTED("Login() NDKMETHOD login with portalUri %s user %s ", event.portalUri, event.userName);
VidyoClientSendEvent(VIDYO_CLIENT_IN_EVENT_LOGIN, &event, sizeof(VidyoClientInEventLogIn));
FUNCTION_EXIT;

}

我得到了一个out事件，我试图像这样处理（调用我试图发送给NDK的接口的onResponse方法）：

 // Send message to Client/application
    VIDYO_CLIENT_LOG_INFO("GuiOnOutEvent NDKMETHOD VIDYO_CLIENT_OUT_EVENT_SIGNED_IN sign in successful");
    jboolean isAttached;
    VIDYO_CLIENT_LOG_INFO("GuiOnOutEvent NDKMETHOD VIDYO_CLIENT_OUT_EVENT_SIGNED_OUT sign in successful2");
    JNIEnv *env;
    VIDYO_CLIENT_LOG_INFO("GuiOnOutEvent NDKMETHOD VIDYO_CLIENT_OUT_EVENT_SIGNED_OUT sign in successful3");
    env = getJniEnv(&isAttached);
    VIDYO_CLIENT_LOG_INFO("GuiOnOutEvent NDKMETHOD1 VIDYO_CLIENT_OUT_EVENT_SIGNED_IN mid has been initialised");
    jstring js = (*env)->NewStringUTF(env, "");
    VIDYO_CLIENT_LOG_INFO("GuiOnOutEvent NDKMETHOD1 VIDYO_CLIENT_OUT_EVENT_SIGNED_IN js string created");
    (*env)->CallVoidMethod(env, applicationJniObj, methodClass, js , js);

我这样调用登录方法：

    CallbackFromNDK back = new CallbackFromNDK() {
            @Override
            public void onResponse(String code, String response) {
                Log.i("","GuiOnOutEvent NDKMETHOD got out of it");
                Utils.disposeDone = true;
                loginResolved();
            }
        };
        ((VMBaseActivity)getActivity()).app.vidyoCommands.Login(VidyoModApplication.prefManager.getPortal(getActivity()), user, pass, back);

这是来自我的LoginFragment，已打包：package com.vidyo.vidyomod.activities; 我的界面有这个包：package com.vidyo.vidyomod.interfaces;

但是因为我在登录片段中创建CallbackFromNDK时尝试调用登录，我甚至得到back.getClass().toString()这个：com.vidyo.vidyomod.activities.LoginFragment$2

在我的ndk代码中，它会转到(*env)->CallVoidMethod(env, applicationJniObj, methodClass, js , js);并收到此错误：

06-06 17:17:10.335: E/art(26772): JNI DETECTED ERROR IN APPLICATION: can't call void com.vidyo.vidyomod.activities.LoginFragment$2.onResponse(java.lang.String, java.lang.String) on instance of com.vidyo.vidyomod.VidyoModApplication

为什么不让我称这个功能？

需要将一个函数作为参数从Android传递到JNI接口
