    Great course, really well delivered in a clear and logical way. So many aspects of
    android are covered it creates a great platform from which to start developing Apps
    for the android products.

  2. 4

    As an introductory course, I think a student cannot ask for more than you offer. It
    really starts assuming zero-knowledge, which has been good to me because I wasn't
    used to the android studio platform.

  3. 4

    I'm a 19 year old first-time developer - no previous coding experience or really
    anything techy. This course was absolutely brilliant for teaching me the
    fundamentals and making me realise that nothing is ever as hard as it seems.

  4. 4

    One of the most fluent and best courses one can find ! Simply amazing ! The
    mentor knows how to explain and the entire course has been very nicely portrayed.
    Must have a course. Go for it!

  5. 4

    This was a very knowledgeable course on the whole. I came as a newbie who just
    knew that there is something called toast in android and now I am returning with a
    lot of beautiful knowledge about building android applications. I am glad that I got to
    learn a new skill from such a good instructor who taught all the concepts very
    patiently and tried to reply to all my queries timely.

  6. 5

    Good course to get started with Android development using Java. The app that we
    built during the course is a great way to apply what we learn. The instructor could
    give more technical and thorough explanation of concepts & apply clean code

  7. 5

    I got to admit, I was pretty unsure when I bought this course, but after going
    through about 2 hours, I am really enjoying it and more importantly, I am learning
    more than I ever thought I would. I would recommend taking notes in the start since
    the java syntax can be a little tricky to get used to.

  8. 5

    I really loved the friendly nature of the teacher. It really made me love the topic.
    Everything is taught step by step and slowly which helped me grasp easily. The
    explanations were crystal clear.

  9. 4

    NullClass is really amazing. As a first time App Developer I have gone through
    numerous Tutors but I kept on making mistakes and felt like I wasn't learning
    anything. Since I started your course I can say it's becoming easier and I now know
    what I am doing. I'm so grateful I enrolled in this course. This is by far the best
    Android Course Available for newAndroid Developers like me.

  10. 5

    In my personal opinion, NullClass tells the lesson really well with a
    comprehensive explanation.. I really enjoy learning android development through
    this course.. Some points where I really need detailed explanation were explained
    really well.. I was amazed with how NullClass did their job and I am enjoying my self
    learning and getting the most of it.. Everybody who wants to start learning Android
    should buy this course.. You will never regret it!

  11. 4

    This course is for absolute beginners, don't hesitate if you're one. It was well
    planned and took things gradually to advance level and for perfection you just
    need to practise and practise more. Thanks to the NullClass!
