Furthermore, the system cannot easily batch these requests When the system triggers exact alarms that your app sets, the deviceĬonsumes a great deal of resources, such as battery life, especially if it's inĪ power-saving mode. Invocation of the alarm can significantly affect the device's resources, Caution: When your app schedules an exact alarm using this method, the Modes if necessary to deliver the alarms. System identifies these alarms as the most critical ones and leaves low-power Highly visible to users, the system never adjusts their delivery time. Invoke an alarm at a precise time in the future. Invoke an alarm at a nearly precise time in the future, even if battery-saving Use this method to set exact alarms, unless your app's work is Invoke an alarm at a nearly precise time in the future, as long as otherīattery-saving measures aren't in effect. Time-critical tasks but demand more system resources. These methodsĪre ordered such that the ones closer to the bottom of the list serve more Your app can set exact alarms using one of the following methods. Note that, if your app targets Android 12 or higher, the smallestĪllowed window length is 10 minutes. User-specified action that can happen within a specified time window Use an inexact alarm. User-specified action that should happen after a specific time Use an inexact alarm. User-specified action that should happen after a specific time (even if system in idle state) Use an inexact alarm. You can provide a repeat interval and flexInterval (15 minutes minimum) toĭefine granular runtime for the work. Scheduled background work, such as updating your app and uploading logs WorkManager provides a way to schedule timing-sensitive periodic Note that these APIs rely on system uptimeĪnd not real time. Methods to handle timing operations, such as doing some work every The following list shows common workflows that may not require an exact alarm: Scheduling timing operations during the lifetime of your app The Handler class includes several good Use cases that might not require exact alarms Note: If your app targets Android 12 or higher, you must Or a calendar app-then it's OK to use an exact alarm instead. If your app's coreįunctionality depends on a precisely-timed alarm-such as for an alarm clock app

Most apps can schedule tasks and events using inexact alarms toĬomplete several common use cases. The system invokes an exact alarm at a precise moment in the future. The time between two consecutive invocations of the alarm can vary. Subsequent alarms usually go off after the specified time windowĮlapses.The first alarm goes off within the specified time window, starting from the.Deliver a repeating alarm at roughly regular intervals

This reason, windowLengthMillis parameter values under 600000 are clipped toĦ00000. The invocation of a time-windowed inexact alarm by at least 10 minutes. If your app targets Android 12 or higher, the system can delay Unless any battery-saving restrictions are in effect, the alarm isĭelivered within the specified time window, starting from the given trigger If your app calls setWindow(), the alarm never goes off before the supplied Hour of the supplied trigger time, unless any battery-saving restrictions areĭoze. On Android 12 (API level 31) and higher, the system invokes the alarm within one The alarm never goes off before the supplied trigger time. If yourĪpp's core functionality depends on a precisely-timed alarm-such as for an alarmĬlock app or a calendar app-then it's OK to use an exact alarmĭevelopers can leverage the following API guarantees to customize the timing of Note: Most apps can schedule tasks and events using inexact alarms. Inexact alarms provide some guarantees regarding the timing ofĪlarm delivery while respecting battery-saving restrictions such asĭoze. When an app sets an inexact alarm, the system delivers the alarm at some point

This approach gives Android better control over system resources. Note: For timing operations that are guaranteed to occur during the lifetime Operations without relying on timers or continuously running services. They help you minimize your app's resource requirements. They operate outside of your application, so you can use them to triggerĮvents or actions even when your app is not running, and even if the device You can use them in conjunction with broadcast receivers to schedule They let you fire Intents at set times and/or intervals.
