This document discusses the MVP+C architecture pattern for mobile applications. C stands for Composer, a class that composes streams of processes and has an activity or fragment lifecycle. The composer handles errors from data sources like servers using Retrofit or local storage with DBFlow. Dependency injection with Dagger and reactive programming with RxJava are also discussed. Sample projects and links are provided to learn more about MVP+C and its technologies.

4. MVP+C. Background
Programming, at its core, is about data transformation. And the case for
most mobile applications, it is about data transformation, data composition,
and UI presentation

5. RxJava to the rescue!

6. MVP+C. What is the C?

7. MVP+C. What is the C?
C is for Composer.

8. MVP+C. What is the C?
C is for Composer.
Composer is a class that has lifecycle (activity, fragment, dialog, etc) in
order to compose the stream of a process.

9. 1
RxJava for compose stream
2 Dagger for Dependency Injection
3 Data source and Error handling

10. RxJava

14. RxJava
Do not use Rx if there is no “event”.

18. Dagger

19. Dagger
Make your class loose coupling between other class.

26. Dagger
Make easy to create unit test

29. Data source
&
Error handling

30. Data source
● Server
○ Handle the communication to server using Retrofit
○ Every request call to server MUST handle error
● Local
○ Save data into local
■ Shared Preference
■ DBFlow

31. Error handling
Railway Oriented Programming

32. Error handling
● Kinds of error:
○ NetworkError
○ NoInternetError
○ TokenExpiredError
○ UnknownError
○ ResultEmptyError
● All Error passed to composer
