[@germancedres1114]

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

[@badradnan8309]

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

[@somethingheimer]

My code for 3:12:55 is fun avg(a: Any, b: Any) : Double { val a = a.toString().toDouble() val b = b.toString().toDouble() return (a + b) / 2 } So basically you can give it anything (int or double) and it will return a double. The only problem is that you can give it a string.

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

Thanks a lot for your heart warming comment. I am super happy that there are people like you, who enjoy my teaching style. And btw, don't worry about not memorizing everything. It's like with human languages. The more you use them, the more natural they become

@@tutorialsEU Hi Denis. first thanks for your great course, I learned a lot from you. and I wanted to buy your full android kotlin course, but in the website there was something called per/month! I didn't get how it works, I mean how can I just buy your android kotlin course and download it to have it on my PC, is it possible? thanks :)

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

[@ManoelNunesOSan]

Awesome course. And you explain everything very well and with detail. The only problem is that you mistakenly say "brackets" instead of "parenthesis" and "parenthesis" instead of "double quotes".

I've been looking for this exact tutorial. Am experienced in other languages and have developed Android apps using flutter, just wanted to go deeper; this exactly satisfied my needs. Good work.

[@arismendygill8792]

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.

[@ujastechie]

Can a folder be made for each topic?

[@lucagiaco]

Hi! Thanks for the 9+ hours class. I was browsing the full course on Android Firebase and the shop app.. and checking the Course's steps i couldn't find any step on payment methods. Is it taught there anyway? And what about price rules and promotions? I'd like trying to make some shopping apps that built the structure of products categories and sub categories by parsing the organization of folders and subFolders on a server or shared folder.. and that could find in each of those folders a .csv file containing the code, name, infos, price and availability of the products and other than that .csv file also a list of images corresponding to the products listed in the .csv file. Which masterclass would you suggest me? Is the Firebase Firestone - Shop app course enaugh? Thanks!!!!

Hello, Denis! First of all, thank you so much for the awesome course! I currently moved to Happy Places chapter but I noticed that all the previous chapters have been updated for Android 12. Could you please tell me when the rest of the chapters will be updated? (Especially interested in Happy Places). Thank you!

Hi lucky devil. My plan was for my Assistent teacher to update the last two remaining chapters. When that will happen is uncertain, as I am still searching for a great assistent teacher. :-) The trello clone will not get an update.

3:25:39 Help!! after unannotated the "nullablename = null", why "nullablename?.let { println(it.length)}" indicate error on my pc thanks for helping!!!!

[@Carolus_64]

It is the same for me. also nullableName?.let{ println(it.toLowerCase())} does not work, the compiler signals an overload resolution ambiguity. I think that using if(nullableName != null) println(nullableName.length) is better

[@Carolus_64]

Found the key!! you have to assign nullableName = (null as String?). When assigning nullableName= null the variable takes the type Nothing? causing various errors. The class Nothing has not the method length The class Nothing is a subclass of both Char and String classes, so the compiler don't know which toLowerCase method should be used. My opinion is that seems a bug of Kotlin language, but I'm new to Kotlin so I don't judge
