Broadcast Receiver is one of the five major Android components and is frequently used.
It is used to receive broadcast Intent asynchronously. The broadcast Intent is sent by calling Context. sendBroadcast () and BroadcastReceiver are used to receive broadcast Intent asynchronously. sendBroadcast (), Context. sendOrderedBroadcast () or Context. sendStickyBroadcast. General
When a situation occurs on an Android system, all programs must be notified of processing, such as low power, and the broadcast intent object can be used to broadcast information.The operating mechanism consists of two parts: The program that sends out the intent object, the program that listens to the broadcast information (broadcast Receiver), its province is a class, must inherit the Broadcastreceiver class, must register with the system, and speci

Let's guess what go will do with it.
Let's make a pact: the receiver can be thought of as the first parameter of the function, that is: func M1(t T) func M2(t *T) Go is not an object-oriented language, so it may be biased to understand that it looks like object-oriented syntax.
When called t1.M1() , the M1(t1) argument and the row parameter are both t

Why do I need to use delegation? There is a method somewhere in the event receiver that handles the event. This event is executed every time a registered event occurs.Program. In this case, you need to use the delegate. Since the sender does not know anything about the receiver, it is impossible to set
corresponding to the kernel space ). The specific sending and receiving ends are completed by the TCP protocol. Although TCP is reliable, the premise is that the transmission end is connected to the receiving end's network, otherwise you will understand. In this way, if you want to determine whether the receiver has successfully received data by calling send (), you have to look for other methods.2. Send () blocking and non-blocking
