安排 AlarmManager 进行定期后台数据同步的最佳位置在哪里？
我的 Android 应用程序将定期轮询服务器以检查数据。我希望无论用户与应用程序的交互如何，都会发生这种轮询，类似于（在概念上）Gmail 和 Google Reader 应用程序在后台同步数据的方式。安装应用程序后，这些定期同步就会开始发生。我不认为从Activity内部安排警报是可行的方法，因为我不想等待用户打开我的应用程序。
在这种情况下，调用AlarmManager.setInexactRepeating的最佳实践是什么？
我能想到的一些可能性是：
- 扩展
Application并在onCreate中执行 - 从设置为
的。Service中进行调度清单中的 android:enabled=true - 侦听某些特定的广播消息，并从接收器内进行调度
My Android application will be periodically polling a server to check for data. I want this polling to happen regardless of user interaction with the application, similar (in concept) to how the Gmail and Google Reader apps sync data in the background. Once the app is installed, these periodic syncs should begin happening. I do not think that scheduling the alarm from inside an Activity is the way to go, because I do not want to wait for the user to open my application.
What is the best practice in this case for placing the call to AlarmManager.setInexactRepeating?
Some possibilities I could think of are:
- Extend
Applicationand do it inonCreate - Do the scheduling from within a
Servicethat is set toandroid:enabled=truewithin the manifest. - Listen for some particular broadcast message(s), and schedule from within a receiver

创建一个启动接收器并使用它来启动安排警报的服务。查看此链接：http://www.thetekblog.com/?p=77
Create a on boot receiver and use it to start a service that schedules the alarm. Check out this link: http://www.thetekblog.com/?p=77
“在清单中设置为 android:enabled=true 的服务中进行调度。”
默认情况下启用服务 - 但这并不意味着任何东西都会自动启动它。在配置中禁用服务的唯一原因是您在某处有一些代码可以以编程方式启用它。
"Do the scheduling from within a Service that is set to android:enabled=true within the manifest."
A service is enabled by default - but that doesn't mean anything would start it automatically. The only reason a service would be disabled in configuration is if you have some code somewhere that enables it programmatically.
