To build out our word game, we will have to be able to share the word across a few places. This means we have to set up a broadcaster that will push the same values to multiple listeners instead of different values each time a listener is added. We will d
To display a sequence of values in React, we can use our mapSequence operator, wrap it around a broadcaster, then pass that new broadcaster into our useBroadcaster we defined. This will demonstrate that any broadcaster we've defined before should wor
Many streams of events end when a certain condition is met. When we run into that condition, we'll want to pass down our own custom values. This lessons walks through adding a done condition to hangman and how we can use new operators to control what
After a broadcaster is "done", starting it up again requires calling the broadcaster with the same listener. This creates a kind of "async recursion" where you pass the listener back into the broadcaster each time you set it up. This l

广播类型： 全局：其它APP可以收到（可以说是;public） 本地：只有自己APP收到（可以说是：private） 广播机制： 无序：接收端不可修改，不可拦截 有序：接收端：可修改，可拦截 一、本地广播： 广播定义： public class Broadcaster { private static Broadcaster sInstance; private Context mContex
