推荐答案

从的Andr​​oid 3.0开始，应用状态进行了介绍。 所有的应用程序现在的状态设置为停用安装，使得它所有的BroadcastReceivers无效。

Starting from Android 3.0, application state was introduced. All applications are now installed with a state set to inactive, making all it's BroadcastReceivers inactive.

为使国家作为活动的，用户必须启动应用程序至少一次，操作系统会自动启动应用程序及其所有BroadcastReceivers。

To make the state as active, the user must launch the application at least once and the OS will automatically activate the app and all its BroadcastReceivers.

在你的情况，你需要添加一个活动，无论是许可协议或帮助页面。这将为你的应用程序的图标供用户点击并激活该应用程序。

In your case, you need to add an activity, be it a license agreement or a help page. This will create an icon for your app for the user to click and activate the app.

请注意，该应用程序的状态将被设置为不活动的备份，如果用户强制关闭应用程序。

Note that the application's state will be set to back inactive if the user force-closes the application.
