What is broadcastreceiver for? is an implementation of the observer pattern mechanism Broadcastreceiver is usually out of wait until the event it subscribes to is triggered As with Activity,contentprovider, you need to inherit broadcastreceiver and register in manifest How do I subscribe to events? How does the event issue a broadcast? What kind of broadcast do you use to express? Broadcast is divided into ordinary broadcast and orderly broadcast The system receives
