    Great quiz, I enjoyed it. However, it includes a mistake. In my opinion number four is wrong.

    Q: Which of the following would you use to handle background tasks in an Android app?

    My answer: Thread. Because then it really runs in the background and is not blocking the main thread. You said that the correct answer is Service. I think that is wrong, because by default a Service runs on the main thread and blocks the UI. In this case it only handles tasks, but not in the background!

    Anyways, there were some great questions.

      Hi Ralf

      Thanks for the feedback. From the developer guide:

      A service is a component that runs in the background to perform long-running operations or to perform work for remote processes.

      I agree that you might choose a thread for some background tasks but the aim of the quiz is really to test basic application fundamentals knowledge, i.e. what is the purpose of a service etc. Maybe the wording of the question is a little confusing.

    “An orc would have performed just as good as you! You scored 55.56%”

    I think that’s decent considering I have been able to get no farther than installing the SDK in eclipse because my PC won’t run emulators. Was fun to see what I could guess based on logic though.
