你可以动态注册这个类与Context.registerReceiver（实例），或者通过静态在AndroidManifest.xml中注意标签发布实施。如果注册一个接收器在你的Activity.onResume（）的实现，你应当注销其在Activity.onPause（）。（暂停时，您将不会收到意图，这将减少不必要的系统开销）。请不要在Activity.onSaveInstanceState（）没有注销。

"You can either dynamically register an instance of this class with Context.registerReceiver() or statically publish an implementation through the tag in your AndroidManifest.xml. Note: If registering a receiver in your Activity.onResume() implementation, you should unregister it in Activity.onPause(). (You won't receive intents when paused, and this will cut down on unnecessary system overhead). Do not unregister in Activity.onSaveInstanceState()."

:) SDK是你最好的朋友。我想说做它在SDK中说，除非你绝对需要接收器暂停时，但要小心。你有动态注册接收器或将其放置在AndroidManifest.xml会更好？如果你把接收器清单，你就不用担心注册/注销了。

:) The SDK is your best friend. I would say do what it says in the SDK unless you absolutely need the receiver when paused but be careful. Do you have to dynamically register the receiver or would putting it in the AndroidManifest.xml be better? If you put the receiver in the manifest you won't need to worry about registering/unregistering it.
