About the test

The Android and Java online test assesses knowledge of the developing Android applications using its primary programming language, Java.

The assessment includes work-sample tasks such as:

  • Configuring UI elements, such as list view and linear layout.
  • Understanding the life cycle of an activity and working within it.
  • Working with classes, objects, and interfaces to write reusable code.

A good Android app developer needs to effectively use the Android SDK and the Java programming language to design and create quality Android applications.

Sample candidate report

What others say

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
