First, IntroductionBroadcast receiver is a broadcast receiver that receives custom and system anchors. It can also be called a listener.Broadcast intent, like intent, is the medium of communication, and unlike intent, broadcast intent is received by multiple components at the same time.Broadcast intent broadcast mechanism, broadcast sources emit messages, and through AMS (Activity Manager service), multiple

As the name suggests, braodcast receiver is a broadcast receiver. It is similar to the time processing mechanism, but the event processing mechanism is program component-level (for example, the Click Event of a button ), the broadcast event processing mechanism is system-level. We can use intent to start a component, or use the sendbroadcast () method to initiate a system-level event broadcast to transmit m

Android automatically exits the FM Radio application when the flight mode is enabled and the headset is pulled out. The FM radio needs to be inserted into the headset as an antenna, and automatically exits when the headset is pulled out. 1.

We described the broadcast mechanism of the Android system, in essence, it is a message subscription/advertisement mechanism, so the first step to use such a message-driven model is to subscribe to the message, and for Android applications, the subscription message is actually a register broadcast receiver, This article explores how the
