Usually, your application shouldn't be about the whitelist Except Doze or Application Standby split the core purpose on the app or You will find there's specialized cause why your app can't use FCM large-precedence messages.
In Doze or App Standby manner, the method delivers the message and offers the app momentary access to network services and partial wakelocks, then returns the system or app to the idle condition. Higher-priority FCM messages will not in any other case have an effect on Doze manner, plus they don’t have an effect on the state of almost every other app. This means that your app can use them to speak efficiently although minimizing battery impacts across the technique and product. As a standard best observe, When your app involves downstream messaging, it should really use FCM. In the event your server and shopper currently works by using FCM, Guantee that your service works by using large-priority messages for crucial messages, given that this may reliably wake apps even though the machine is in Doze. Support for other use scenarios
With these strategies, you'll be able to set alarms which will fireplace although the machine is in Doze. Be aware: Neither setAndAllowWhileIdle() nor setExactAndAllowWhileIdle() can fireplace alarms in excess of after for every 9 minutes, for each application. The Doze restriction on network access is also more likely to have an effect on your application, particularly when the app depends on real-time messages like tickles or notifications. In the event your app needs a persistent relationship on the community to acquire messages, you need to use Firebase Cloud Messaging (FCM) if possible. To substantiate that the application behaves as predicted with Doze, You should utilize adb instructions to pressure the technique to enter and exit Doze and notice your application’s conduct. For information, see Testing with Doze and App Standby. Comprehending App Standby
$ adb shell dumpsys deviceidle power-idle When Prepared, exit idle mode by managing the subsequent command:
If possible, use FCM for downstream messaging. When your users have to see a read notification without delay, make sure to use an FCM substantial priority message. Provide sufficient info throughout the First message payload, so subsequent community accessibility is pointless.

No, are unable to use FCM on account of complex dependency on Yet another messaging service or Doze and Application Standby crack the core operate with the application.
The desk below highlights the suitable use situations for requesting or being over the Battery Optimizations exceptions whitelist.
Furthermore, it prevents applications from accessing the network and defers their Employment, syncs, and normal alarms. Periodically, the technique exits Doze for a short time for you to Permit apps entire their deferred activities. For the duration of this maintenance window
Alarms established with setAlarmClock() continue to fireside Typically — the program exits Doze Soon in advance of those alarms fire. The program does not carry out Wi-Fi scans. The program won't permit sync adapters to run. The program does not let JobScheduler to run. Doze checklist
The next restrictions apply for your apps when in Doze: Network entry is suspended. The technique ignores wake locks. Typical AlarmManager alarms (together with setExact() and setWindow()) are deferred to another servicing window. If you might want to set alarms that fireplace even though in Doze, use setAndAllowWhileIdle() or setExactAndAllowWhileIdle().
