Where is my standard library?!

“If you find yourself doing something by yourself, you’re probably doing it in the wrong way”

- Somebody at Google’s Android team

Networking‣ The standard way:

Retrofit by Square

‣ Turns your HTTP API into a Java interface

‣ Using GSON as JSON parser

‣ Stupidly easy to use

Image Loading

‣ Images are not trivial:

‣ Memory consumption

‣ Network

‣ Main players:

‣ Picasso (Square)

‣ Glide

‣ Fresco (Facebook)

‣ UIImageLoader

Picasso by Square

‣ Lightweight

‣ Fluent API

http://square.github.io/picasso/

Dagger by Square & Google

‣ Dependency Injection library

‣ Adopted by Google (Dagger vs Guice)

‣ Dagger 2

‣ simple, traceable and performant

http://google.github.io/dagger/

ButterKnife by Jake Wharton ‣ View binding framework

‣ Less boilerplate code

With ButterKnife

Otto by Square

‣ An enhanced event bus with emphasis on Android support

‣ Forked from Guava (Google’s Java Library)

Stetho by Facebook ‣ A debug bridge for Android applications via

Chrome Developer Tools

‣ Network Inspection

‣ View Hierarchy

‣ Database Inspection

‣ Javascript Console
