My opinion of broadcast receiver

1. For communication between components and components, can be implemented within a program or within multiple programs!

2. The transmitted data is very small, very low frequency

3. Low operating efficiency, very slow

4. Broadcast receiver is not allowed with frequent communication

5.sendBroadcast (Intent) which is also the way to use Intent jump

6.registerReciver (Broadcast entry,new Intentfilter (action)) registration

7.unregisterRectiver () logoff

8. Life cycle is only about 10 seconds, if within onreceive () do more than 10 seconds of things, will be error
