Mar 12, Updated documentation. Updated to the new SDK version.Alarms based on the AlarmManager class give you a way to perform time-based operations outside the lifetime of your application. For example, you could use an alarm to initiate a long-running operation, such as starting a service once a day to download a weather forecast. Note: For timing operations that are guaranteed to occur during the lifetime of your application, instead consider using the Handler class in conjunction with Timer and Thread.

This approach gives Android better control over system resources. A repeating alarm is a relatively simple mechanism with limited flexibility. It may not be the best choice for your app, particularly if you need to trigger network operations.

A poorly designed alarm can cause battery drain and put a significant load on servers. A common scenario for triggering an operation outside the lifetime of your app is syncing data with a server.

This is a case where you might be tempted to use a repeating alarm. But if you own the server that is hosting your app's data, using Google Cloud Messaging GCM in conjunction with sync adapter is a better solution than AlarmManager. A sync adapter gives you all the same scheduling options as AlarmManagerbut it offers you significantly more flexibility.

See the linked videos at the top of this page for a detailed discussion of when and how to use GCM and sync adapter. Alarms do not fire when the device is idle in Doze mode. Any scheduled alarms will be deferred until the device exits Doze. If you need to ensure that your work completes even when the device is idle there are several options available. Another option is to use the new WorkManager API, which is built to perform background work either once or periodically.

For more information, see Schedule tasks with WorkManager. Every choice you make in designing your repeating alarm can have consequences in how your app uses or abuses system resources. For example, imagine a popular app that syncs with a server. If the sync operation is based on clock time and every instance of the app syncs at p. Use setInexactRepeating instead of setRepeating.

When you use setInexactRepeatingAndroid 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.

As of Android 4. Note that while setInexactRepeating is an improvement over setRepeatingit can still overwhelm a server if every instance of an app hits the server around the same time. Therefore, for network requests, add some randomness to your alarms, as discussed above. Repeating alarms that are based on a precise trigger time don't scale well. The different alarm types are described in more detail in the following section.

As described above, repeating alarms are a good choice for scheduling regular events or data lookups. A repeating alarm has the following characteristics:. There are two general clock types for alarms: "elapsed real time" and "real time clock" RTC. Elapsed real time uses the "time since system boot" as a reference, and real time clock uses UTC wall clock time.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
