Jetpack architectural components

I saw someone before introducing the AAC (Android Archicture Components), said to be a new application architecture, and holds many lessons can solve encountered in the development of the factors of disharmony

1. LifecyclesI believe many people have already used it, in fact, the role of this thing is to be transferred to the business layer Activity / Fragment life cycle by listeners mode only
2. LiveData, And this stuff just makes sense to use with Lifecycles, based on observer mode, and can sense the life cycle of the holders of the class
3. ViewModel+ Data Binding: This thing is mvvm things Well
4. Room, Looked at the source code, all kinds of notes, in fact, is the stuff of database operations
5. WorkManager : This thing is really a good thing, providing a one-stop solution to our implementation of background tasks;
6. Paging : The ability to help us cope with load large data problems;
7. Navigation: It is no use doing this they get to know, look back
