广播接收器被视为服务吗？
我正在挖掘这个论坛，但找不到我的问题的答案....
1，我通过扩展广播接收器开发了短信应用程序，一切都运行良好，问题是手机休眠一段时间后 - 应用程序是不再工作了。那么broadcastreceiver被认为是一个服务吗？ （它会在闲置X分钟后被Android杀死）....因为我没有像我在服务中那样的“START_REDELIVER_INTENT”....并且我读了一些帖子说要使用AlarmManaget - 但我不明白为什么。 （示例帖子不是关于接收短信的……而是关于日历等……）
底线 - 我该如何解决这个问题？如果我需要使用一个服务在 android 杀死它后自行运行 - 我不明白如何将我的广播接收器转换为服务......（因为它是唯一需要运行的东西......其他一切都是只是设置和首选项....)
2，例如，当我安装 GOSMS 时，Android 会问我 - 从现在开始我想使用哪个应用程序作为我的默认短信程序，我需要编写什么代码才能实现向最终用户发出此类通知？现在我的应用程序只接收短信通知...不发送任何内容...
提前致谢...
I was digging this forum but couldn't find an answer to my questions ....
1, I developed SMS application by extending broadcastreceiver and everything is working great, the problem is that after the phone is sleeping for a while - the application is no longer working. So is broadcastreceiver considered a Service ? ( that will be killed by the Android after it's been idled for X minutes ).... because I don't have the "START_REDELIVER_INTENT" like I have inside a Service .... and I read some posts that said to use the AlarmManaget - but I don't understand why. ( the examples posts were not about receiving SMS though ... were in regards to calendars etc ... )
Bottom line - how do I fix this ? if I need to use a service to run itself after the android kills it - I don't understand how to convert my broadcastreceiver to be a service... ( because it's the only thing that needs to be running ... everything else is just settings and preferences ....)
2, When I install GOSMS for example, the android ask me - from now on which app would I like to work with as my default SMS program, what to I need to code in order to achieve this kind of notification to the end-users ? right now my application only receive SMS notifications ... doesn't send anything ...
Thanks in advance....

不，这就是为什么它被称为
BroadcastReceiver而不是Service。请参阅应用程序基础知识以正确理解 Android 应用程序的各个关键组件。
另外，如果您在
AndroidManifest.xml中正确注册了BroadcastReceiver'sIntents，尽管正如Jens提到的，这可能需要您获取某种WakeLock（并在任务完成期间/之后正确获取/处理/释放各种资源）。No, that's why it's called
BroadcastReceiverand notService.Please see Application Fundamentals to properly understand the various key components of an Android application.
Also, if you have correctly registered your
BroadcastReceiver's<intent-filter>in yourAndroidManifest.xmlthen it will be 'woken up' to processIntentsalthough as Jens mentions that may require you acquiring aWakeLockof some sort (and correctly acquiring/handling/releasing various resources during/after your task is accomplished).
