Skills to look for in an Android SDK Developer

Android, is the dominant mobile operating system today, running on smartphones tablets, and various other devices. As a result, there can be a lot of competition when it comes to recruiting a new Android SDK Developer. You will need to work out who is the right candidate and fast, to stay ahead of the competition.

Firstly, your candidate will need to understand the architecture of the Android platform, processes launched during app startup, threads started, and the ways in which the application communicates with the system and other applications. They will need to possess knowledge of the basic components of the platform: Android SDK, but also Activity, Fragment, Intent, BroadcastReceiver, and ContentProvider, as well as knowledge of the basic and the most popular libraries supporting the creation of applications, Android Support Library, Google Play SDKs, Retrofit, OkHTTP, rxJava, EventBus, and Dagger.

Check out Java programming tests

Your Android SDK developer will also have to implement easy architecture and design patterns, which enable writing applications in a way that allows easy maintenance, extension, and testing, and be up to date with the latest trends in MVP and MVVM.

They should also be familiar with the rules concerning the creation of efficient views and the ability to create reusable custom views and possess an ability to deal with market fragmentation and the mechanisms Android offers, to ensure the smooth operation of the application on devices with varying specifications, from screen size and density to different language versions and different versions of the system itself. Your candidate should also be familiar with the different names given to each version of Android from C-N (Cupcake, Donut, etc).

You can test your applicants’ experience based on the number of applications they have released on Google Play and if these are still available, check what they look like, how they work, and how many downloads they have. It is also worth finding out how large the developer’s team was and their specific role in the project.
