Buen video!! buenisimo!! saludos desde Argentina. Nuevo Sub :)

why you use light theme

sir i cant able to access workingsTV directly in main activity what is the solution sir?

Hey Cal, if we can't use this anymore apply plugin: 'kotlin-android-extentions'
then what should I do for the program to run?

awesome explanation and development thank you Cal

mine remained orange throught all the buttons

My buttons are not calling the the style variables. They are just remaining default

whenever i press on any operator my app automatically ends .?.?.?

Thanks for teaching this. New subscriber

Im learning the android right now , but when I added the kotlin android extension, it shows errors that says the extentions not found. anyone can help me?

Thank you! Was very helpful!

Hey Cal, thanks for video but code is giving that error. How can we solve that?


Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Float
at com.example.calculator.MainActivity.calcTimesDiv(MainActivity.kt:108)
at com.example.calculator.MainActivity.timeDivisionCalculate(MainActivity.kt:92)
at com.example.calculator.MainActivity.calculateResults(MainActivity.kt:61)
at com.example.calculator.MainActivity.equalsAction(MainActivity.kt:54

Honestly I loved the way you approached it and learned a lot from this video, even though it's not a long one.

if ( timesDivision.isEmpty() ) return""

can anyone please explain why this line is written ??

after pressing backspace button its not working properly

Man that was tooooooooooooooooooooooooo fast 😳

Nice video but it was fast

idk if you'll see this now but can i get help on kt. page. for some reason workingsTV and resultsTV are in red?

pls add modulo

Explain things in much more details. I think it is not for absolute beginners.

Bro I make caculeter o m g thanks you

can u go faster u dwarf

Play this at .75x speed. Your welcome

wowowow slow down man, boom bam bam done, I do know java, but not kotlin and not android studio ui, but it's abit too fast, unless you pause every second :D

Way too fast

workingTv is nnot funtional in my program

hey, awesome video, but when you used the (" apply plugin: 'kotlin-android-extensions' ") it says it is no longer supported, what should I do to fix this? Thank you very much!!

What do I do? <LinearLayout will not work for some reason even though I'm typing the code the exact same way

Plugin with id 'kotlin-androids-extensions' not found.

Thank you brother <3

great video Cal...

Bro were not coding with cal you are coding we are copying. i dont like ur super fast phase video's

You made this tutorial AN ENTIRE 9 MONTHS after it was announced that the Android Kotlin Extensions Gradle plugin was no longer going to be supported?

I did the view binding but still not working. I almost give up

All this android tutorials are non sense and waste of time we learn nothing from this
Everybody just tell what they and typing there, its totally fucking waste of time and we follow it blindly

Can I know how to add the modulo operations in the existing code given by you

Thanks for the tutorial it helped me

jesus christ slow down

pausing and playing your video is kinda defeating the purpose.
why dont you make a write up?

very fast ((((

kotlin-android-extensions is depreciated. Can you make an update video with how to change this finished project so that it's compatible?

Hey Cal, first of all. Thanks for your code and knowledge, it's been so helpful. I have a question about your code, I noticed that if you put the negative value first, it won't do the operation. For example: -99 + 1 and if you click the equal button, there will be no operation or just -1 and equal button, error too. Could you please give me some advice to fix this? Thanks anyway for your solution

My takeaway from this video was using of styles. Thanks 🙏

I named the file with the same file name and copied the code. I did not write it myself, but there are a lot of errors. Does anyone know the reason? error in workingsTV. There are yet other errors.

A tutorial is meant to teach but you are just there doing your thing for us to watch, no teaching at all in this video. And the speed is just 😢
