应该报警管理器发送的PendingIntent到IntentService还是更将其发送到广播接收器，然后发出startService（）针对未决的意图是什么？

Should alarm manager send PendingIntent to IntentService or is it better to send it to a broadcast receiver which then issues startService() targeting the pending intent?

推荐答案

这取决于这是否是一个 _WAKEUP 报警或不是有点。

That depends a bit on whether this is a _WAKEUP alarm or not.

如果没有，随意使用的getService（） 的PendingIntent 。

If not, feel free to use a getService() PendingIntent.

如果，但是，它是一个 _WAKEUP 报警，你不仅需要使用广播接收器中介，但广播接收器还必须获取激活锁定其中 IntentService 更高版本。在广播接收器要求是由于方式 AlarmManager 处理自己的激活锁定。我已经包裹所有这一切都成一个 WakefulIntentService 简化实施

If, however, it is a _WAKEUP alarm, not only do you need to use a BroadcastReceiver intermediary, but that BroadcastReceiver must also acquire a WakeLock which the IntentService later releases. The BroadcastReceiver requirement is due to the way AlarmManager handles its own WakeLock. I have wrapped all of this up as a WakefulIntentService to simplify the implementation.
