无法初始化显示事件接收器

我做了一个应用程序,定期启动一个服务,从服务器检索信息。

我使用AlarmManager来安排服务。
这工作正常,应用程序每30分钟收到一次警报。
该应用程序工作正常,但经过一整夜的不活动 – 我启动应用程序,它崩溃的错误:“无法初始化显示事件接收器”。

否则这个作品完美。

我search了这个问题很久,发现其他人有同样的问题,但没有解决scheme。

只是为了一些信息

只是为了一些信息,我不明白为什么,信息抛出:

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

或者也许这个

 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:

  /* initCheck returns the state of DisplayEventReceiver after construction.*/ status_t initCheck() const; 

并看看DisplayEventReceiver.cpp

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

看起来像mDataChannel是NULL,

mDataChannel在构造函数中初始化

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

所以sf的SurfaceComposer是NULL或sf-> createDisplayEventConnection返回NULL。

并在./system/core/include/utils/Errors.h文件中

 ... 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NO_INIT
