I think the issue was by ths following , for @TheWanderer who helped me through his comment to find the answer. In the Android 8.0 Behavior Changes Note developers mentioned the following:
code :
private AnprEventReciever myReceiver;
private IntentFilter filter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_video_resource);

    filter = new IntentFilter();
    filter.addAction(Intent.ACTION_AIRPLANE_MODE_CHANGED);
    myReceiver = new AnprEventReciever();
}

@Override
protected void onResume() {
    super.onResume();
    registerReceiver(myReceiver, filter);
}

@Override
protected void onPause() {
    super.onPause();
    unregisterReceiver(myReceiver);
}

I wish this help you As mentioned in the question, and the following shows mu code .. , I think you never raise any broadcast. Your code shows:
code :
Intent i = new Intent(c,AlarmReceiver.class);
i.putExtra("alarm_message", "Hello, Alarm is running !");
PendingIntent pi= PendingIntent.getActivity(c, 19237, i, PendingIntent.FLAG_UPDATE_CURRENT);

fixed the issue. Will look into that further I have 5 fragments on a ViewPager (they're all in memory all the time, onPause() and such are never called while the containing Activity is on screen). , I am using this code that is working well
code :
@Override
public void onResume() {
    super.onResume();
    if (myReceiver == null) {
        myReceiver = new UpdateGroupsReceiver(this);
        IntentFilter filter = new IntentFilter(
              UpdateGroupsReceiver.UPDATE_TIMETABLE_ACTION);
        registerReceiver(myReceiver, filter);
    }
}

public void updateStatus() {
    Intent intent = new Intent();
    intent.setAction(UpdateGroupsReceiver.UPDATE_TIMETABLE_ACTION);
    sendBroadcast(intent);
}

wish of those help You should register and unregister your receivers in onResume() and in onPause() respectively. Cause if you only register it in onCreate() and unregister in onPause(), then the next time the activity is brought to the foreground, onCreate() will not be called again and then it will not register the receiver again. But onResume() is always called on the activity being displayed.
code :
public void onResume() {
    super.onResume();
    ....
    registerReceiver(myBroadcastReceiver, intentFilter);
}

public void onPause() {
    super.onPause();
    ...
    unregisterReceiver(myBroadcastReceiver);
}

will be helpful for those in need Local
You register receiver as global, but send intents via LocalBroadcastManager. If you want to use this manager you should register your receiver like this:
code :
LocalBroadcastManager.GetInstance(this).RegisterReceiver(lbr, filter);
var intent = new Intent(this, typeof(LocationBroadcastReciever));
this.SendBroadcast(intent);
[IntentFilter(new []{ "test" })]
[BroadcastReceiver]
public class LocationBroadcastReciever : BroadcastReceiver { ... }

I think the issue was by ths following , The problem here was not adding the line myIntentFilter.addAction(getString(R.string.broadcast_id)); while registering the BroadcastReceiver.
It got solved after adding the line.
