没有主要业务推出Android应用程序和启动应用程序启动服务 [英] Launch Android application without main Activity and start Service on launching application

问题描述

我在application.There一个场景是在我的应用程序没有用户界面，取而代之的是在开始启动时，将连续运行一个服务

I have a scenario in my application.There is no UI in my application;instead there is a Service which starts on boot up and will continuously run.

我该如何配置我的清单文件中没有一个主要的活动？我可以启动我的应用程序没有任何活动？而就发动我的应用程序，我的服务应该启动。以任何方式这可能吗？ 我不想让半透明的活动，以启动该服务。

How can I configure my manifest file without a main Activity? Can I launch my app without any Activity? And on launching my app, my Service should start. Is this possible in any way? I don't want to make translucent activities to start the service.

在此先感谢！

推荐答案

你说你不想使用半透明的活动，但是，这似乎是做到这一点的最好办法：

You said you didn't want to use a translucent Activity, but that seems to be the best way to do this:

1. 在您的清单，设定活动主题，以 Theme.Translucent.NoTitleBar 。
2. 请不要与你的活动布局麻烦，不叫的setContentView（）。
3. 在活动的的onCreate（），与启动服务startService（）。
4. 退出的活动结束（）一旦你开始了服务。

1. In your Manifest, set the Activity theme to Theme.Translucent.NoTitleBar.
2. Don't bother with a layout for your Activity, and don't call setContentView().
3. In your Activity's onCreate(), start your Service with startService().
4. Exit the Activity with finish() once you've started the Service.

在换句话说，你的活动不必是可见的;它可以简单地确保您的服务正在运行，然后退出，这听起来像你想要的。

In other words, your Activity doesn't have to be visible; it can simply make sure your Service is running and then exit, which sounds like what you want.

我会强烈建议出至少吐司通知指示，你是用户启动服务，或者说，它已在运行。这是非常不好的用户体验有，似乎什么也不做，当你preSS它发射器的图标。

I would highly recommend showing at least a Toast notification indicating to the user that you are launching the Service, or that it is already running. It is very bad user experience to have a launcher icon that appears to do nothing when you press it.
