Please help me out, a wakeful broadcast receiver is not called, I have set an Alarm with the help of Alarm Manager using setExactAndAllowIdle() with RTC_WAKEUP but still, my broadcast receiver not getting called when App is closed (means App is swiped from Recent Apps). I am working on android 8. Actually, I want to create an Alarm App that fires at the exact time which set, even if the App is closed or the device is locked.

It may be because the WakefulBroadcastReceiver has been deprecated as of Android O and should generally not be used anymore. From the documentation:
Deprecated: As of Android O, background check restrictions make this class no longer generally useful. (It is generally not safe to start a service from the receipt of a broadcast, because you don't have any guarantees that your app is in the foreground at this point and thus allowed to do so.) Instead, developers should use android.app.job.JobScheduler to schedule a job, and this does not require that the app hold a wake lock while doing so (the system will take care of holding a wake lock for the job).
