在此设想情景 :

我有一个服务 我想从装置启动时间开始

此服务将监听多播集包, 并向用户发送通知 。

为了让服务开始在系统启动器上运行,我需要定义一个接收器, 监听一个意图连接以下动作android.intent. action.BOOT_COMPLETED , 该动作将启动服务 。

如果我有N级的应用程序, 所有人都期待这项服务在运行, 我在所有应用程序中定义了同一个接收器, 我假设将启动N级的服务数量。

是否有办法防止同一服务的多种情况发生?

问题回答

机器人服务公司实际上是单吨, 意思是说 任何时候都只有一次运行。

根据API文件 ,每次拨打startService () 都会触发 onStartCommand () 事件;然而,如果服务已经运行,则不会启动新的服务实例。
