I have made an app which periodically starts a service that retrieves information from a server.
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’.
Else this works perfectly.
I searched this problem for a long time and found others with the same problem, but no solution, yet.

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);
or maybe this
frameworks/base/libs/androidfw/DisplayEventDispatcher.cpp:1427: ALOGW("Failed to initialize display event receiver, status=%d", result);
the status -2147483648 = 0x800000000
it return from the DisplayEventReceiver:
/* initCheck returns the state of DisplayEventReceiver after construction.*/
status_t initCheck() const;
and look at the DisplayEventReceiver.cpp
status_t DisplayEventReceiver::initCheck() const {
if (mDataChannel != NULL)
return NO_ERROR;
return NO_INIT;
}
look like the mDataChannel is NULL,
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();
}
}
}
so sf SurfaceComposer is NULL or the sf-> createDisplayEventConnection return NULL.
and in the file ./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,
...
seems the status must NO_INIT…
