You have have detemined the amount of time (interval) to execute a snippet of code, its better to use <a href="http://developer.android.com/reference/android/app/AlarmManager.html" rel="noreferrer">AlarmManager</a> because its more energy effient. If your app needs to listen to some sort of a event , then Service is what you need.

<pre><code>public static void registerAlarm(Context context) {
 Intent i = new Intent(context, YOURBROADCASTRECIEVER.class);

 PendingIntent sender = PendingIntent.getBroadcast(context,REQUEST_CODE, i, 0);

 // We want the alarm to go off 3 seconds from now.
 long firstTime = SystemClock.elapsedRealtime();
 firstTime += 3 * 1000;//start 3 seconds after first register.

 // Schedule the alarm!
 AlarmManager am = (AlarmManager) context
 .getSystemService(ALARM_SERVICE);
 am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, firstTime,
 600000, sender);//10min interval

}
</code></pre>

Alarm Manager (system service) vs Remote Service with inner alarm implementation (separate process)?

Alarm Manager is your choice, because it already has what you need, you just have to set alarm intervals

blocks|key|114803|text|您也可以通过SyncAdapter来实现这一点。这里是一个示例，供您查看并获得灵感|type|unstyled|depth|inlineStyleRanges|entityRanges|data|114804|SyncAdapter+sample|offset|length|114805|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/android/platform_development/blob/2d52182dfac91014c2975a1bb1afd99a3b14b4e9/samples/SampleSyncAdapter/src/com/example/android/samplesync/syncadapter/SyncAdapter.java^0|0|0|I|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

blocks|key|332405|text|工作管理器实际上是定期重复的最好方法，他们的默认值是15分钟，这与你需要的完全一样。下面是一个示例：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|332406|++++++++final+PeriodicWorkRequest+periodicWorkRequest

Work manager is actually the best thing to do with periodically repeat, their default is 15 minutes which exactly like you need.
Here is an example:

<pre><code> final PeriodicWorkRequest periodicWorkRequest
 = new PeriodicWorkRequest.Builder(ApiWorker.class, 15, TimeUnit.MINUTES)
 .build();
 WorkManager.getInstance().enqueue(periodicWorkRequest);
</code></pre>

Where ApiWorker is just the following class:

<pre><code>public class ApiWorker extends Worker implements iOnApiRequestSuccessful {

public ApiWorker(@NonNull Context context, @NonNull WorkerParameters workerParams) {
 super(context, workerParams);
}

@NonNull
@Override
public Result doWork() {
 return Result.success();
}
}
</code></pre>

And fill whatever work you want to be done in the doWork() function before the return with success.

Return.success() makes it inserted to the queue again so it will be repeated every 15 minutes.

I need to build a background task that runs every 10/15 minutes (doesn't really matter, either is good), even when the application is not running.

How can I accomplish this? I can't seem the wrap my head around this.

I read I could use some sort of runnable() functionality or use a background services or AlarmManager. I was thinking of a background service, since it also must be done when the application itself is not running.

What is a better way of doing this and how could I do it?

Android - Running a background task every 15 minutes, even when application is not running

我需要构建一个每10/15分钟运行一次的后台任务(这并不重要，也很好)，即使应用程序没有运行。我如何才能做到这一点呢？我似乎不能理解这件事。我读到我可以使用某种runnable()功能，或者使用后台服务或AlarmManager。我在考虑后台服务，因为它也必须在应用程序本身不运行时完成。做这件事有什么更好的方法?我该怎...
