android – Failed to initialize display event receiver

Posted by: admin April 23, 2020 Leave a comment

Questions:

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

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
