无法初始化显示事件接收器 [英] Failed to initialize display event receiver

问题描述

我制作了一个应用程序，该应用程序定期启动一项从服务器检索信息的服务.

I have made an app which periodically starts a service that retrieves information from a server.

我使用AlarmManager来安排服务.
这可以正常工作，并且该应用程序每30分钟收到一次警报.
该应用程序运行良好，但是经过一整夜的不活动后-我启动了该应用程序，该应用程序崩溃并显示以下错误:无法初始化显示事件接收器".

I use an AlarmManager to schedule the service.
This works fine and the app receives the alarm every 30 min.
The app works fine, but after a full night of inactivity -and I start the app, it crashes with the error: 'Failed to initialize display event receiver'.

否则，这很完美.

我搜索了很长时间这个问题，并发现了其他同样的问题，但是还没有解决的方法.

I searched this problem for a long time and found others with the same problem, but no solution, yet.

推荐答案

仅提供一些信息，我不明白为什么， 消息来自:

Just for some info, I can't understand why, The message throws from :

frameworks/base/core/jni/android_view_DisplayEventReceiver.cpp:4239:        message.appendFormat("Failed to initialize display event receiver.  status=%d", status);

或者也许

frameworks/base/libs/androidfw/DisplayEventDispatcher.cpp:1427:        ALOGW("Failed to initialize display event receiver, status=%d", result);

status -2147483648 = 0x800000000

它从DisplayEventReceiver返回:

it return from the DisplayEventReceiver:

  /* initCheck returns the state of DisplayEventReceiver after construction.*/

status_t initCheck() const;

并查看DisplayEventReceiver.cpp

and look at the DisplayEventReceiver.cpp

status_t DisplayEventReceiver::initCheck() const {
if (mDataChannel != NULL)
    return NO_ERROR;
return NO_INIT;
}

看起来mDataChannel为NULL

在构造函数中初始化的mDataChannel

the mDataChannel initialized in the constructor

DisplayEventReceiver::DisplayEventReceiver() {
    sp<ISurfaceComposer> sf(ComposerService::getComposerService());
    if (sf != NULL) {
        mEventConnection = sf->createDisplayEventConnection();
        if (mEventConnection != NULL) {
            mDataChannel = mEventConnection->getDataChannel();
        }
    }
}

因此sf SurfaceComposer为NULL或sf-> createDisplayEventConnection返回NULL.

so sf SurfaceComposer is NULL or the sf-> createDisplayEventConnection return NULL.

和文件./system/core/include/utils/Errors.h

...
NO_ERROR            =0
UNKNOWN_ERROR       = (-2147483647-1), // INT32_MIN value

NO_MEMORY           = -ENOMEM,
INVALID_OPERATION   = -ENOSYS,
BAD_VALUE           = -EINVAL,
BAD_TYPE            = (UNKNOWN_ERROR + 1),
NO_INIT             = -ENODEV,
...

似乎状态必须为NO_INIT ...

seems the status must NO_INIT...
