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 public questions

10 min
Inversion of Control

Refactor the AlertService and MapAlertDAO classes:

  • Create a new package-private interface, named AlertDAO, that contains the same methods as MapAlertDAO.
  • MapAlertDAO should implement the AlertDAO interface.
  • AlertService should have a public constructor that accepts AlertDAO.
  • The raiseAlert and getAlertTime methods should use the object passed through the constructor.
3 min

Consider the following code:

protected void onResume() {
    mp = MediaPlayer.create(getBaseContext(), R.raw.sound);
    Thread timer = new Thread() {
        public void run() {
            try {
                Intent main = new Intent(Splash.this, MainActivity.class);
            } catch (InterruptedException e) {}

protected void onPause() {
    if (mp != null) {
        if (mp.isPlaying()) {
        mp = null;

Select the statements that are correct if the wave file sound is 3 seconds long.

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.
