Shakir Ahmed Al Alwan

Of course, the course is very interesting, and the explanation of the lesson is very clear. Through repeated hands-on doing, I will get the course benefits.

All course topics explanation is very clear and perfect to the course intent, except the first part of the required software program installation in lieu of the software updates. I wish that you can add attachment related to this issue as constructive comment.

Sergio Olarte

Great course! I already have some background experience with programming, so I was able to fast forward a little bit. However, all lectures were somehow useful and of course, here is a lot you can do on your own after this to improve learning. If you do all the exercises properly it might take a few months to complete, but it would be totally worth it. Thanks to COVID-19 I was able to find the time (and price discount) to finish it.


4. Android Java Masterclass – Become an App Developer

The main objective of this course is to teach you how to build Android apps that are backward compatible with older versions of Android.

One of the main advantages of taking this Android development course on Udemy is that you’ll get to learn from a very passionate instructor who also keeps his courses updated.

This is something that you’ll not find from other courses as most instructors create their courses once and never care to update them, even after the technologies they are teaching get outdated.

While learning how to build Android apps for the latest version of Android Nougat, you’ll also learn AppCompat, which is a set of support libraries that when used, make apps developed in newer Android version work with older versions.

This approach to learning Android development is a little unique as most tutorials only focus on teaching the current version of Android.

However, by also leveraging older version of Android, your apps are able to reach more users, which leads to more downloads on the Play Store… more money.

I find this course very interesting for learning Android development because of the numerous challenges that are particularly designed to help you to understand each content that is being taught.

Student feedback

Raphael Baron

I have followed quite a few classes on Udemy for Android Developpement and this is, by far the best in my opinion. It is better maintained than some courses that were created more recently.

Very useful and enjoyable course that teaches all the core skills required to make virtually any app. Lessons were clear and structured however on rare occasions the methods/code has since been updated meaning the taught method no longer works, the correct method is usually then given in the questions section but it would be nice if the lessons were updated.

Javed Ahsan

It’s a brilliant course. Paulo repeats techniques in a way that we can practice well. A very comprehensive course.

I didn’t follow the Java part as I already knew it, however, I skipped through it, and it’s well organised.

I loved this course a lot and liked Angela. Providing information in a useful and easy way. Not boring, quite the opposite, sitting for an enjoyable long time. Everything was great until chapter 20 and beyond. I wished that the focus was greater on the Play Store because the idea of ​​the course is based on developing applications using Java and Android.

I found this course very well made.
It covers an enormous amount of content but doesn’t overwhelm you with information, it takes you through step by step.

The only remark I have is that the course is missing one last section meaning that the app that we have spent hours creating isn’t quite finished at the end of the course (May 2020).

Student feedback

Simone Semprini

IT would be useful a bit of a dive into the language features… I have some solid background, but for most of the people, I think that a good part of the examples are not easy to understand since they don’t get the meaning of the code they see.

Sometimes the (as usual) too verbose approach of the Java world to things makes it difficult to understand why it is necessary to write so much code to achieve a simple task, in those cases, rather than throwing the code to the students it would be good explaining it.

Student feedback

Baskar K S

Course was evenly paced but it had a lot of coding to be done. This course focuses on MVC, and Observer Patterns. Reading about them should be mention in the prior reading. Further, Android Studio (and even IntelliJ Idea) require a lot of RAM to build, run (using emulator). I had to work in late night to do coding and after completing my course, I will do read the bookmarks again and practice. I wish there could some editor so that practice can be done fast enough. Most of persons don’t have 8 or 16GB RAM in systems for practice.
