获取服务中的上下文 [英] Get Context in a Service

问题描述

是否有任何可靠的方法可以从 Service 获取 Context?

Is there any reliable way to get a Context from a Service?

我想为 ACTION_PHONE_STATE_CHANGED 注册一个广播接收器，但我不需要我的应用程序总是获取这些信息，所以我没有把它放在 Manifest 中.

I want to register a broadcast receiver for ACTION_PHONE_STATE_CHANGED but I don't need my app to always get this information, so I don't put it in the Manifest.

但是，当我需要这些信息时，我不能让广播接收器被 GC 杀死，所以我在 Service 中注册了广播接收器.

However, I can't have the broadcast receiver be killed by the GC when I need this information so I'm registering the broadcast receiver in a Service.

因此，我需要一个 Context 来调用 registerReceiver().当我不再需要 ACTION_PHONE_STATE_CHANGED 时，我取消注册.

Hence, I need a Context to to call registerReceiver(). When I no longer need the ACTION_PHONE_STATE_CHANGED I unregister it.

有什么建议吗?
