ALARM MANAGER, . - Coggle Diagram

- - - - If you simply need your alarm to fire at a particular interval (for example, every half hour)
  - - - If you need your alarm to fire at a particular time of day
    - - The app may not translate well to other locales, and if the user changes the device's time setting, it could cause unexpected behavior in your app. Using a real time clock alarm type also does not scale well, as discussed above. We recommend that you use an "elapsed real time" alarm if you can.
- - - - such as Doze
        
        DON'T WORK IN DOZE MODE
        
        USE WORKMANAGER INSTEAD
    - - Use setInexactRepeating() instead of setRepeating(). When you use setInexactRepeating(), Android synchronizes repeating alarms from multiple apps and fires them at the same time. This reduces the total number of times the system must wake the device, thus reducing drain on the battery.
    - - To perform work while the device is in Doze, create an inexact alarm using setAndAllowWhileIdle(), and start a job from the alarm.
  - - - When the system triggers exact alarms that your app sets, the device consumes a great deal of resources, such as battery life
    - - <uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM"/>
        
        must be granted by the user.
