Intro to rxjava

As part of the educational programs in e-Legion, we give lectures on Android development in the ITIS KFU laboratory . We decided to share two of them with you. Lectures are devoted to the increasingly popular framework RxJava.

Lecture 1

The lecture tells about:

• General ideas of the RxJava framework, why it is needed and how to work with it
• Ways to create various Observable and the most basic operations on them
• The main conversion operators are Observable, as well as the cache method
• Observable join operations and their sequential / parallel execution.

Presentation .

In addition, as part of the class it was proposed to solve 4 practical tasks in order to better master the material. You can also try your hand (link to all test projects and examples at the end).

Lecture 2

The second lecture is devoted to using RxJava and RxAndroid in the real world when developing applications.

• Considered the remaining entities Rx: Subscription, Subject, Schedulers and their purpose
• Various options for building application architecture with RxJava
• Libraries using and intended for RxJava: trello-lifecycle, RxBinding, RxPermissions.

Presentation .

Within the class there were 2 practical tasks: one for paralleling and query management, the second, more general, building a simple architecture with RxJava and periodically updating data from the server.
