Nguyen Hoang Anh is an Android developer with 4 years of experience currently utilizing a stack that includes Dagger 1, ButterKnife, RxJava, and Retrofit. The document details various tools and libraries used in Android development, highlighting the transition to Dagger 2 for better obfuscation and support while also discussing other libraries for handling views, asynchronous programming, and image loading. Additionally, it mentions ORM options like Realm.io and GreenDAO, emphasizing the importance of unit testing in development.
What we use to build Android apps at Silicon Straits
- 1. About me • Nguyen Hoang Anh. • Developing for 4 years now. • Just recently made a switch to Android.
- 2. Our Android stack • Dagger 1 • ButterKnife • RxJava & RxAndroid • Retrofit • Picasso • Realm.io / GreenDAO
- 3. Dagger 1.x • Dependency injection framework. • Developed by Square. • Been in production for more than 2 years. • http://square.github.io/dagger/
- 4. Dagger 1.x • Code generation, partially reflection. • Has some problems with obfuscation.
- 5. Dagger 2 • Forked from Dagger 1, developed by Google. • Fully code generation, no reflection. • Obfuscation works. • We will make our transition to Dagger 2 soon.
- 6. ButterKnife • Views injection library. • Developed by @JakeWharton. • http://jakewharton.github.io/butterknife/
- 7. ButterKnife
- 8. RxJava • A JVM-based Reactive Extension. • Programming against asynchronous observables. • https://github.com/ReactiveX/RxJava
- 9. RxJava building blocks • Observables: all the heavy works. • Subscribers: consume the data. • Operators: map(), flatMap(), filter() … • Schedulers.
- 10. RxAndroid • Provides AndroidSchedulers.mainThread() • https://github.com/ReactiveX/RxAndroid
- 11. Retrolambda • Because we like this fancy arrow -> • Joking, it’s really unbearable working with RxJava without Lambda. • https://github.com/evant/gradle-retrolambda
- 12. Example • Chaining observables: flatMap()
- 13. Example • Convert data to another type: map()
- 14. Retrofit • Developed by Square • Version 1.9.0 • Square is rolling out version 2.0 • http://square.github.io/retrofit/
- 15. Retrofit 1.9.0 • Turn your REST API into a Java interface. • Add request information using Annotation. • Support rx.Observables.
- 16. Retrofit
- 17. Retrofit
- 18. Picasso • Image loader made easy. • Easy to use API. • Developed by Square. • http://square.github.io/picasso/
- 19. Picasso
- 20. Database • Realm.io • GreenDAO • Both are ORMs but GreenDAO current supports unit testing a lot better.
- 21. Unit tests • Robolectric • Mockito • JUnit 4
- 22. Summary • We do have day job. • Make use of what already there. • Proven libraries.
