 Android jetpack designed to work well with Kotlin, saving you even more code with Android KTX. 
Key area's of architecture component of jet pack



Each of these jetpack components is individually adaptable and they built to work well together.

Next is architecture component which is designed such way to resolve the developer pain point, some of them like lifecycle management, data persistence.
                  


Three new architecture component is seen below image


  

Paging facilitates gradual on-demand data loading from local or network data source allowing apps to work with large datasets including support recycler view.





Navigation provides the framework to build app flows that compile with android design guidelines with proper behavior for up and back button.

 Support for
  1. Deep linking 
  2. Automated fragment transactions
  3. Overflow Menu
  4. Navigation Drawer
  5. Bottom Navigation show in above pic

Work Manager makes it easy to schedule one-off or periodic asynchronous tasks.
Tasks can executes in order, Parallel or even more configurations.


Its also easy to query for the state of tasks and constraints, such as requiring unneeded network or charging Perhaps most importantly work manager takes care of compatibility issues, so you know that no matter what platform the user is on tasks are scheduled efficiently and system wide health in mind
