RxJava is a library for composing asynchronous and event-based programs using observable sequences. It provides features for concurrency, request management, data flow manipulation, and error handling. RxJava uses streams and new objects like Schedulers, Subscriptions, and Subjects. It can be used with techniques like retained fragments, cached observables, binding to lifecycles, and services to handle configuration changes and loading data.

2. RxJava main advantages
• Concurrency
• Requests Managment
• Data flow manipulation
• Error handling
• Cool, trendy, etc

3. Everything is a stream

9. Some new Rx objects

10. Schedulers
• computation
• io
• newThread
• from
• + AndroidSchedulers.mainThread

12. Subscription

18. Subject
Can be both Observable and Observer

19. PublishSubject

20. PublishSubject

21. PublishSubject

26. Result?

39. Solution

41. But how to handle configuration changes?

42. Use Rx in conjunction with
• Retain Fragments
• Cached Observables

43. Subscription

44. Use Rx in conjunction with
• Retain Fragments
• Cached Observables
• Bind Rx to Lifecycle
• Loaders
• Services
