我怎么知道何时从广播接收器与Android调用我的服务？

[英]How do I know when my service is called from a broadcast receiver vs Android?

原文 2013-11-22 18:28:13 2 1 java/ android/ android-intent/ android-service/ android-broadcast

So, I have a service for my app that is always running if the user turns it on. 因此，我为我的应用程序提供了一项服务，如果用户打开它，该服务将一直运行。 It listens with a broadcast receiver for USER_PRESENT to show a message. 它用广播接收器侦听USER_PRESENT以显示一条消息。 It is only supposed to show a message on unlocking. 它仅应在解锁时显示一条消息。

The problem is though, when Android runs out of memory and kills it, then restarts it, it will show the message again, even if the user hasn't just unlocked their device. 但是问题是，当Android内存不足并杀死它，然后重新启动它时，即使用户不只是解锁设备，它也会再次显示该消息。 Is there a way to know who called the service? 有没有办法知道谁打电话给服务？

I use service.START_NOT_STICKY , but would service.START_STICKY be better for this job? 我使用service.START_NOT_STICKY ，但是service.START_STICKY可以胜任这项工作吗？ I guess I don't fully understand the differences but I'm pretty sure I want NOT_STICKY . 我猜我不太了解这些差异，但是我很确定我想要NOT_STICKY 。

You can set the action field in the intent to a specific string when you call your receiver and then check it in onReceieve . 您可以在调用接收方时将intent的action字段设置为特定字符串，然后在onReceieve中onReceieve进行检查。

If it has your string then you called it , otherwise someone else. 如果它包含您的字符串，则您将其称为，否则调用其他人。
