4. Beginner Intermediate Advanced Target Audience
5. Blueprints is an architecture a testing project. • UI Testing as a Spec Fast, reliable and hermetic • Decent unit test coverage Mockito, MockableAndroidJar, no Robolectric, no powermock • Use Non-UI Android tests Test against real implementations, compatibility testing
6. A to-do app
7. todo-mvp/ - Basic Model-View-Presenter architecture todo-mvp-loaders/ - Fetches data using Loaders todo-mvp-contentproviders/ - Uses Content Providers todo-databinding/ - Uses the Data Binding Library todo-mvp-clean/ - Uses concepts from Clean Architecture todo-mvp-dagger/ - Uses Dagger2 for Dependency Injection todo-mvp-rxjava/ - Uses RxJava for concurrency and data layer abstraction dev-todo-mvvm-databinding/ - Model View View Model based on todo-databinding dev-todo-mvvm-rxjava/ - Model View View Model based on todo-mvp-rxjava todo-mvp-fragmentless/ - Uses Android views instead of Fragments todo-mvp-conductor/ - Single Activity + Conductor framework todo-mvp-tablet/ - Phone + Tablet version Stable In development External In review
8. UI Testing as a contract
10. Travis
11. circleci
12. Firebase Test Lab
13. Design decisions Flavors (mock/prod) Minifier / shrinker Fragments Simulated network calls
14. Blueprints is a collection of samples platform for Android devs. • Learning • Outreach/discuss • Base for sample or template for app • GitHub cred ★★★★★
15. How to use Blueprints
16. Browse on GitHub github.com/googlesamples/ android-architecture
17. Compare locally Diffs between branches are as small as possible $ git clone https://github.com/ googlesamples/ android-architecture.git $ git checkout todo-mvp $ git difftool -d todo-mvp-clean
18. meld
20. todo-mvp
21. todo-mvp-clean
22. todo-mvp-contentproviders
23. todo-databinding
24. Findings Dex method count APK size IRRELEVANT (if you shrink)
25. Dex count
26. APK size
28. HELP! • Answer questions and reply to issues • Wiki and articles • Create samples (read guidelines!) • Become core maintainer (merge-master)
29. Contribution examples
30. V2: What is coming • Focusing on underlying patterns ◦ MVVM, MVC, Redux, Flux… • Other apps, different spec • Improve platform for discussion
