Android development in 2019 @soulesidibe 2
The purpose of this talk
The purpose of this talk • The tools • How
we build android apps • Is it worth it to build native apps • ⤴ Flutter, Ionic, React native ⤴ = native apps
Numbers
Numbers • Android 1.0 (Relese date 2008) • Android 2.3
(Relese date 2011) Gingerbread • Android 10 (2019) Source: Statcounter
Numbers • 76% of the Mobile Operating system market share.
Worldwide • 83% of Africa Market share • 90% of Senegal Market share • 40% of OS market share behind Windows. Source: Statcounter
Numbers • The most popular OS in Africa • The
most accessible OS (cheap phones) • An open OS • Millions of apps available

Architecture A style and method of design and construction.
Architecture • Onboarding new devs is easier • Focus on
the feature not on the plumbing • The team speak the same language • Write testable code • Team size: 1+
Architecture • Old Android (XML Activity) • MVP (Model View
Presenter) • MVVM (Model View ViewModel)
Google Opinion
Testing
Test • FOR ME • UI Testing is mandatory •
Unit testing is good • 100% coverage means nothing
Test • Unit Testing(Junit, Mockito, etc) • UI Testing (Espresso,
Robolectric) • Firebase Test Lab
Wrap up
Wrap up • Native android development is stable • Still
evolving • Huge community(Conferences, open source, libraries) • At scale, “native is best”
Alternatives
Alternatives • React Native(js) • Ionic(js) • Flutter(dart)
Pros • One code base/one team • Well known web
technologies • Easy to find talented devs
Cons • One code base but 2 targets • Javascript
• Some native features not available for both android and IOS
Conclusion • Android for life! • But Flutter is really
great • Learn both!
Thanks!
