Generally speaking, your app really should not be on the whitelist unless Doze or Application Standby split the Main operate from the application or There exists a technological cause why your application cannot use FCM substantial-precedence messages.
In Doze or Application Standby method, the procedure provides the information and provides the application temporary access to community services and partial wakelocks, then returns the gadget or app into the idle condition. Substantial-priority FCM messages usually do not usually affect Doze manner, they usually don’t have an affect on the point out of almost every other app. Because of this your app can rely on them to communicate successfully even though minimizing battery impacts across the process and unit. As being a basic very best observe, If the app necessitates downstream messaging, it need to use FCM. Should your server and shopper previously utilizes FCM, Ensure that your service takes advantage of superior-precedence messages for vital messages, since this could reliably wake applications regardless if the unit is in Doze. Guidance for other use instances
Using these methods, it is possible to established alarms that should fireplace even though the system is in Doze. Observe: Neither setAndAllowWhileIdle() nor setExactAndAllowWhileIdle() can hearth alarms much more than once for every nine minutes, for every application. The Doze restriction on network accessibility is additionally prone to influence your application, particularly when the application depends on true-time messages which include tickles or notifications. In case your app requires a persistent relationship to your network to get messages, you must use Firebase Cloud Messaging (FCM) if possible. To confirm that the application behaves as predicted with Doze, You should use adb commands to pressure the system to enter and exit Doze and observe your application’s habits. For facts, see Testing with Doze and App Standby. Knowing App Standby
After a while, the process schedules routine maintenance Home windows much less and less usually, helping to cut down battery use in cases of extended-expression inactivity once the unit isn't linked to a charger. Once the consumer wakes the system by going it, turning around the display screen, or connecting a charger, the program exits Doze and all applications linked here return to regular activity. Doze limitations
If at all possible, use FCM for downstream messaging. If the end users will have to see a notification instantly, You should definitely use an FCM superior priority message. Offer sufficient information inside the Preliminary information payload, so subsequent network access is unnecessary.

No, can't use FCM due to technical dependency on Yet another messaging service or Doze and App Standby split the Main operate on the app.
The desk under highlights the suitable use cases for requesting or staying on the Battery Optimizations exceptions whitelist.
Codelabs: Quick, self-paced tutorials that each deal with a discrete subject matter. Most codelabs step you through the process of building a tiny app, or incorporating a completely new function to an existing application.
The application generates a notification that people see over the lock monitor or during the notification tray. The application is really an Energetic unit admin app (for example, a tool coverage controller). Though they generally operate from the track record, device admin applications never ever enter Application Standby mainly because they ought to continue to be accessible to obtain plan from the server Anytime. When the consumer plugs the device into a power source, the program releases applications from your standby condition, permitting them to freely entry the community also to execute any pending Employment and syncs. If the system is idle for extensive periods of time, the program will allow idle apps network accessibility all over once per day. Working with FCM to connect with your application when the device is idle
The subsequent limitations utilize on your apps while in Doze: Network obtain is suspended. The program ignores wake locks. Regular AlarmManager alarms (together with setExact() and setWindow()) are deferred to the following routine maintenance window. If you must established alarms that fireplace whilst in Doze, use setAndAllowWhileIdle() or setExactAndAllowWhileIdle().
