[@sushantchoudhary444]

thanks bro you saved me

[@filipecomimesmo]

for those searching for it, the name of the symbol is "erase to the left".

[@asmaatharwt5209]

you can get it from vector resource its name is"backspace" and treat with butten as imageButton

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?

[@hamzaakgun5527]

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

[@CodeWithCal]

Thanks a lot, really kind of you to say :)

[@bramantawisnu]

i use 0.25 speed ,, becouse that very fast,, like magic tric 😁

[@salomeshunamon]

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

[@chocolatelover326]

Exactly bcz of translation it get hide...

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

[@kgomotso_nxumalo]

[@ashenmalindu73]

Good tutorial, but it feels a bit slow. Maybe speed it up a little? 😊

[@tafman]

Nice tutorial, we really appreciate for your time making videos like this, it's really helping people like us who are new to coding... 5:02 how/where did you get that button from because it's not on my keyboard?

[@rishabnegi2334]

i also have same doubt. How you are able to enter that button

[@tafman]

@@rishabnegi2334 Found the solution... Its a code that you'll enter in the space given there

[@CodeWithCal]

I just copied the character from the internet ;)

[@Alvarez_Isaac]

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

[@wiki-SMART]

I love you!.. Great work!.. Thank you!

[@tnt_popcorn__]

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

[@lordcinder]

Play this at .75x speed. Your welcome

[@CodeWithCal]

😂

[@RaneemSarminy]

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.

[@p.soumyasundarsubudhi6007]

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

[@emilianomartinezpena5420]

Gracias este video es asombroso

[@omerbabo]

Thank you brother

[@AyushRaj-ml5nf]

if ( timesDivision.isEmpty() ) return"" can anyone please explain why this line is written ??

[@miracleukaka4085]

If the list returned by the timeDivide function is empty, we want the function that called it to return an empty string to the result.

[@wendiiyau]

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

[@CodeWithCal]

The way google would like us to do it now is with view binding :)

[@morfeoraikonen]

Great video keep it going , new subscribe right here :D

[@CodeWithCal]

Thanks 😊

[@AYJ959]

after pressing backspace button its not working properly

[@preetthee]

The kotlin extensions plugins not working. it's saying that "the 'kotlin-android-extensions' gradle plugin is deprecated"

[@CodeWithCal]

Ah yes, I built this tutorial using synthetics, when the new way is view bindings. Have you used view bindings before?

[@preetthee]

Thanks. I got it now.

[@anubhavbagri5204]

@@preetthee Could you share your github code repo link? its not working for me as well. And since I'm new, I'm unable to figure out how to use view bindings

[@bryansantana1212]

@@CodeWithCal Hey Cal, I know this is old but can you explain how to use view bindings? I tried to google it, but the tutorial I am using is not breaking it down easily. If you know of a good tutorial out there, that would work.

[@groverkennedy2049]

Thanks a lot my dude

[@vascocastel-branco3370]

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!!

[@ashfaqueshaikh4177]

U can use view binding

[@calibur5518]

hi how i can change my out put from 160000.0 to 16,000

[@CodeWithCal]

Replace result.toString With a check to remove decimal place if not necessary, you could use a string formatter or round the float. discuss.kotlinlang.org/t/how-do-you-round-a-number-to-n-decimal-places/8843

workingTv is nnot funtional in my program

[@vascocastel-branco3370]

you have to create a variabel like this " name_of_variable = findViewById(R.id.name_of_textview) " (inside onCreate) and than " private lateinit var workingsTV: TextView " (above and outside onCreate)

good work!

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?

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

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

[@CodeWithCal]

What does it say in your console. Googling the exception is usually a good first step

[@umarajmal6216]

@@CodeWithCal it’s throwing a null exception

[@CodeWithCal]

Nice. So trace back why it's null. Or make it null safe?

how to code for +/- sign can you please give any code for it I tried it but my functionality didn't work

[@aanjaliiii]

hi it was awesome my division and multiply is not working

[@CodeWithCal]

🤔 entirely possible I've overlooked something. What have you found?

[@aanjaliiii]

@@CodeWithCal I am new to this, I just followed your code but my divide and multiplication button is not working

[@CodeWithCal]

​@@aanjaliiii Programming can be tricky business. And things don't necessarily always work the first time. But don't be discouraged keep trying and you will get there. Try to understand why the multiplication and division isn't working and then if you are still stuck ask a specific question. General statements like it doesn't work makes it very difficult for me or anyone else to help with the problem. Apologies if thats a little blunt.

[@aanjaliiii]

@@CodeWithCal it's ok.. I get your point

[@robinkalostyan4728]

i got a fail to compile values file error what should ı do?

[@CodeWithCal]

Hmm what does Google say with that error 🤔

[@omur.bilgili]

it have some bugs, but its nice

[@rutgerpronk2754]

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

[@rutgerpronk2754]

You are coding so fast i have you on 0.75 speed and its so frustrating to watch because i cant even keep up hard to even read the colors when you enterd them and dont even explain anything.

[@junekang3168]

Great work!

[@lokesharora4037]

why you use light theme

[@CodeWithCal]

I use both sometimes, doesn't really bother me either way

[@frankndyanabo6047]

mine remained orange throught all the buttons

[@CodeWithCal]

Should just be a change in the XML somewhere to change some buttons to be white

[@usaakshayadhana3149]

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

[@CodeWithCal]

😋

[@tknsoftwarestudio640]

How can I add the parentheses?

[@CodeWithCal]

Probably a bit complicated for a KZbin comment. I have been thinking if doing a part 2 of this tutorial. If I do I'll be sure to include. It is possible good luck 🍀
