android - Failed to initialize display event receiver -


i have made app periodically starts service retrieves information server.

i use alarmmanager schedule service.
works fine , app receives alarm every 30 min.
app works fine, after full night of inactivity -and start app, crashes error: 'failed initialize display event receiver'.

else works perfectly.

i searched problem long time , found others same problem, no solution, yet.

process: it.unipi.iet.portolan.traceroute, pid: 13092 java.lang.runtimeexception: failed initialize display event receiver.  status=-2147483648 @ android.view.displayeventreceiver.nativeinit(native method) @ android.view.displayeventreceiver.<init>(displayeventreceiver.java:61) @ android.view.choreographer$framedisplayeventreceiver.<init>(choreographer.java:695) @ android.view.choreographer.<init>(choreographer.java:169) @ android.view.choreographer.<init>(choreographer.java:72) @ android.view.choreographer$1.initialvalue(choreographer.java:98) @ android.view.choreographer$1.initialvalue(choreographer.java:91) @ java.lang.threadlocal$values.getaftermiss(threadlocal.java:430) @ java.lang.threadlocal.get(threadlocal.java:65) @ android.view.choreographer.getinstance(choreographer.java:194) @ android.view.viewrootimpl.<init>(viewrootimpl.java:370) @ android.view.windowmanagerglobal.addview(windowmanagerglobal.java:248) @ android.view.windowmanagerimpl.addview(windowmanagerimpl.java:69) @ android.app.activitythread.handleresumeactivity(activitythread.java:2871) @ android.app.activitythread.handlelaunchactivity(activitythread.java:2271) @ android.app.activitythread.access$800(activitythread.java:145) @ android.app.activitythread$h.handlemessage(activitythread.java:1206) @ android.os.handler.dispatchmessage(handler.java:102) @ android.os.looper.loop(looper.java:136) @ android.app.activitythread.main(activitythread.java:5141) @ java.lang.reflect.method.invokenative(native method) @ java.lang.reflect.method.invoke(method.java:515) @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:795) @ com.android.internal.os.zygoteinit.main(zygoteinit.java:611) @ dalvik.system.nativestart.main(native method)

just info

just info, can't understand why, message throws :

frameworks/base/core/jni/android_view_displayeventreceiver.cpp:4239:        message.appendformat("failed initialize display event receiver.  status=%d", status);

or maybe this

frameworks/base/libs/androidfw/displayeventdispatcher.cpp:1427:        alogw("failed initialize display event receiver, status=%d", result);

the status -2147483648 = 0x800000000

it return displayeventreceiver:

  /* initcheck returns state of displayeventreceiver after construction.*/  status_t initcheck() const;

and @ displayeventreceiver.cpp

status_t displayeventreceiver::initcheck() const { if (mdatachannel != null)     return no_error; return no_init; }

look mdatachannel null,

the mdatachannel initialized in constructor

displayeventreceiver::displayeventreceiver() {     sp<isurfacecomposer> sf(composerservice::getcomposerservice());     if (sf != null) {         meventconnection = sf->createdisplayeventconnection();         if (meventconnection != null) {             mdatachannel = meventconnection->getdatachannel();         }     } }

so sf surfacecomposer null or sf-> createdisplayeventconnection return null.

and in 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 status must no_init...

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
