我在从贾瓦到C的路口中看到了一些日本国家武装部队的法典。 守则是行之有效的,但如果我对守则施加太多压力(太多指示),就会失事:

在我从贾瓦到C的呼吁中,我保持对我所要呼吁的那类人的全心全意,然后创造新的思路:

JNIEXPORT void JNICALL Java_com_device_client_HostConnection_initialize
(JNIEnv * env, jobject obj, jobject inject)
{
    JavaVM *tmpVM;
    jint result = env->GetJavaVM(&tmpVM);
    if (result < 0) {
        LOGE("Error using GetJavaVM
");
        exit(-1);
    }

    jobject tmpHostObject = env->NewGlobalRef(inject);
    if (tmpHostObject == NULL) {
        LOGE("ERROR: Run out of memory for weak global ref
");
        exit(-1);
    }

    vm = tmpVM;
    hostObject = tmpHostObject;

    pthread_t pth;
    pthread_create(&pth, NULL, startServer, NULL);
    pthread_join(pth, NULL);
}

页: 1 目标是全球变量。 在我的新思路中,我从我沿用的注射器中讲 Java法,并创立了GobalRef:

void *startServer(void* arg)
{
    JNIEnv* env = NULL;
    jmethodID mid;
    jclass hostClass;

    vm->AttachCurrentThread(&env, NULL);

    while (run) {
        /* some code */

        /* Calls a new thread */
        pthread_t pth;
        pthread_create(&pth, NULL, receive, NULL);

        /* more code */
    }
    vm->DetachCurrentThread();
}

void *receive()
{
    jmethodID mid;
    jclass hostClass;
    JNIEnv* env = NULL;

    vm->AttachCurrentThread(&env, NULL)

    while (1) {
        /* receive x, y and action */

        hostClass = env->GetObjectClass(hostObject);
        mid = env->GetMethodID(hostClass, "executeTouch", "(III)V");
        if (mid == 0) {
            LOGD("ERROR: GetMethodID
");
            exit(-1);
        }
        env->CallVoidMethod(hostObject, mid, x * 2, y * 2, action);
    }

    vm->DetachCurrentThread();
}

Does anyone please know what is going on? I am running out of memory please? Why would that be and how could I please avoid it?

EDIT:

我认识到,我没有必要及时找到方法查询系统,我只能把它在当地储存起来,直到(1)。 这确定了我的问题! 谢谢。

Thank you very much.
