问题 it is a tracking app of 24*7. Whenever it stops i use START_REDELIVER_INTENT to restart it, but it is not start every time. It shows below type response in Application manager.

问题 What is the difference between the alarms of type of RTC_WAKEUP and RTC ? From the documenatation of the AlarmManager , it seems that alarms of RTC will not wake up the device if the device current is asleep, and will not delivered until the next time the device wakes up.

问题 I am developing an android-application which main usage is displaying notifications at a set time (some specific calendar app). One of the main complaints is that users do not (always) receive notifications , and I am at wits end. We have internally tested the code below against Android 4.4, 6, 7.0, 7.1, 8.0, 8.1 on emulators and used about 10 real devices (6 to 8.1), and all devices received their notifications on time. Even across reboots, the notifications were all received on time. One of
