Have watched tons of videos on KZbin on this, nothing come close to the clear explanation of code that this video provides. Kudos to Dennis!

[@tutorialsEU]

Glad it helped! I try to it that simple with all my videos, but sometimes others just do it better than me :D

[@yousee5184]

This video doesn’t explain anything

[@zenekquerky7255]

Hey Denise, I have noticed that in your tutorials you use Activities instead of Fragments. And as far as I understood from google, is that Fragments are actually preferred over Activities (if you understand what I mean). Therefore I was wondering why you don't use Fragments ?

[@rogerj.6543]

awesome!!!!! Which version of android studio do you use?

[@min-of8cv]

This channel is so underrated

[@tutorialsEU]

We are working on it!

[@HarderThanCalculus]

my gradle does not show any of this. All I get is the app name, under that app, and under that a crapload of dependencies. I have watched a ton of youtube vids trying to solve the problem but so far nothing will give up SHA1, or anything other than a crapload of dependencies. Getting very frustrated. I know this video is about 5 years old so my comment is probably nothing more than a fart in the wind but any help would be nice!

[@samuelwakoli]

Thanks bro. I really understood how you taught. Im grateful for learning new skill too from you. Thanks

[@MaestroCipher]

Great videos. sha1 considered to be insecure and is not recommended to use, is it possible to use sha256 in this case?

[@dian4729]

the best tutorial you'll find guys 🔥

[@yogeshmishra6025]

Hi denise, does your jetpack compose tutorial uses any deprecated classes? Your other course which I bought was using deprecated and I had to leave that course because of that

[@klaudiaadamus3353]

Thank you for this, I was struggling with the topic since there's really no good (up-to-date) tutorial out there. You helped me a lot and I'm sure I'm going to check out your full course. :)

[@glykeriakirou1216]

Hello I make an application in kotlin and I want to store value radiobutton firebase database kotlin. Have you got an example to help me. Thanks a lot

[@ДмитрийГромов-ф8ч]

in the video at 2:21 minutes you enter the Gradle. I don't have such folders, why?

[@mandy7163]

found some help in this tutorial: kzbin.info/www/bejne/d5mUqItoa9Ggrrs it is hard to understand but the pictures are helpful enough

[@lumbanimakumbi]

Your tutorials are a blessing

[@kautilyabhardwaj3400]

can we use login activity that is already present in the Activity section??

[@lglf77]

I've been attending your classes, but I have a problem that I carry on my conscience. How could I only have a single user per each app device. I read that google doesn't let the app developer from android 10 read the unique IMEI identifier. In the past, I used it like this, I got the email, password, IMEI and a boolean true, from the user's device, if the 4 were ok or returned TRUE in the registration, he could access the app, if he had the email, password, IMEI and false, the user would be blocked. I learned that Firebase's getInstanceId is deprecated and that the return is a temporary token of maximum 1 week and google exchanges it. What would be the logistics for just 1 single registration per smartphone and a lock for that single user, informing a waiting time for unlocking? SOME HELP?

[@webquestions7439]

Thanks for good explanation, very easy to understand. I copied your code, even though app is not throwing errors I cant register user on firebase. On firebase email/password is enabled. Can you hint how I can fix it

[@collinsk8754]

Excellent and straight to the point. Thank you.

[@brianwawczak1039]

HI, I love the video. I am interested in the masterclass, but the link doesn't give the 80% off for me. Is there a coupon code?

[@stunnaman8803]

Thanks bro. Please also do phone number authentication

[@leestephens5262]

[@qaphelanimthembu8514]

19:30 How do we use the Firebase Authentication class?

[@vaibhavwadsamudrakar7328]

how did we directly use firebase.uid if we haven't input any uid earlier?? Please clarify.Very nicely explained.

[@ALEX_K1ND]

val firebaseUser: FirebaseUser = task.result!!.user!! We created variable "firebaseUser" and then we take the uid string from FirebaseUser class

[@FreddaN241]

[@BCS_AAMIRASHRAF]

Thanks sir

[@rjmadeja8769]

hello sir, when I was about to register a user, a toast keeps showing "an internal error has occured. [socket failed: EPERM (operation not permitted)]", what could be the problem here sir? I already added uses-permission in the manifest including promission.INTERNET, permission.ACCESS_NETWORK_STATE, and permission.ACCESS_WIFI_STATE

[@rjmadeja8769]

hello I just solved this problem, for anyone who encountered the same problem just reinstall your virtual device

[@iceCreemShorts]

Thank you

[@Macias096]

how does this work that you didn't declare variable with buttons and text view but it works for you? I've made everything like you from this tutorial and I've got so many errors.

[@Adrian-xf2um]

You need to declare by FindViewById for each button and editable text

[@Macias096]

@@Adrian-xf2um Yeah, I did. And also I'm guessing that he's using viewBinding and automatically all of his id views are recognized

[@maheshwarang4000]

Add this in your gradle app apply plugin: 'kotlin-android-extensions'

Thanks brother

[@beibarysbimbetov6489]

Where do we find your code?

[@soumyabratabiswas8117]

You're doing great. Great contents. The only downside is that downloading your videos from udemy is such a pain. Otherwise great stuff. Love from India...

[@tutorialsEU]

You are not supposed to download videos from Udemy :) They are protected as intellectual property

[@Roads_india]

jcenter() is deprecated. Should i be worried?

[@tutorialsEU]

Hi Code Drugs. Not necessarily. Even if it's deprecated, it will still work.

[@dltnsqo1]
