Dude, i bought your C# masterclass on udemy, and now that i need to learn android, you have a masterclass too. Im working as a unity dev, 1.5+ years. I got this job studying with your classes man. I cant thank you enough

[badradnan]

MARK MY WORDS: this course is good, *BUT* onley for those of already new another programming language (NOT complete beginner) else I am enjoying it

[kopilkaiser]

I wanted to learn Android development in Kotlin. This tutorial is perfect to get a good understanding how to get started on Android dev with Kotlin. Thank you tutorialsEU for making such a useful, important video to learn what I was looking for. I really appreciate it. My best wishes for you to gain knowledge and more success since you are doing such a great job in sharing such valuable knowledge

[arismendygill]

For those new to programming a little advice on how to organize the lessons when it comes to Kotlin. make a new file for each topic, like that if you're looking for for loops or functions etc, you're able to find it faster instead of having a mess in one file.

Another thing if you're using the method "toLowerCase()" and you get a line striking through is because is the old method, now is just "lowercase()". Ignore the quotes lol.

[ibrahimylmaz]

thank you for this. wish you the best bro. I seriously believe that people like you are changing lives.

Hey Denis, thank you so much for sharing the first 9 hours of this course. I have searched the internet and you were already my first choice as teacher. I think it's a great idea to share a portion of your course like this. I'm about to sign up for the course. While coding along here I did begin to feel that there is no way I will remember all the information. But, I see in your full Udemy course, that you include exercises, and quizzes. That is definitely going to help! I intend to finish this full course, and then carry on training in many of your other courses. I have found no errors between your teaching and my application, which is not always the case in online learning. And your precision is confidence building. Many thanks, and I look forward to you being my teacher. Rob
