'Android : with Broadcast Reciever : Notifications are somtimes received at time and sometimes are not recieved at all
Android: with BroadcastReceiver: Notifications are sometimes received at the time and sometimes are not received at all
Tracing the log ---> onReceive() are sometimes called and sometimes are not called which is very strange.
Testing is done on real device --> Note 10 ( Android 12 )
No clear error appears in the log :(
Below are the codes, Appreciate your kind help
