第一次安装 .apk 时如何启动服务

在我的应用程序中，我没有任何 UI 部分，因此我需要在应用程序安装到设备上后立即启动服务.我看到很多链接，答案是它不可能，但我想这肯定是可能的.看看 Android Market 上的 PlanB 应用程序，它确实满足了我的要求.下面是我如何尝试的清单文件，但根本没有调用该服务.所以，让我知道在安装应用程序时启动服务的最佳方式是什么.

In my Application I am not having any UI part, so I need to start a Service as soon as the Applicaton gets installed on the Device. I saw many links from which the answer was that its not possible but I guess it is surely possible. Just have a look at PlanB Application on the Android Market that does fulfil my requirement. Below is my Manifest file how I tried, but the Service was not called at all. So, let me know what is the best possible way to start a Service when the Application gets Installed.

更新

我也尝试使用 android.intent.action.PACKAGE_ADDED 它可以很好地检测其他应用程序的包，但不能正常检测自身.

I also tried using android.intent.action.PACKAGE_ADDED it works fine for detecting the Package for the other Applications but not for itself.
