Its very nice, but please don't rush the teaching, it's better to thoroughly explain each step for what and how it works. ❤
Ok, thank you
thank you so much, Everything was clear and simple,
(I had a problem with the switch but it worked with if)
Sir it is showing error running app no target device found when I am running the mainactivity... What to do??
How to remove error
Case R.id.btn
Constant expression required
What is the error message.
I also get the same error. Anyone who knows to solve this without using if else, please reply!!
same error. how to fix it?
Same error!!
I was getting the same error but then I switched to the if structure, it's working now.
which version of android studio are you using?
How to resolve the error "Constant expression required" on case R.id.btn_add:?
This happens if you use Resources from a Library project. In that case, the the ids in the R class are not really constants and thus cannot be used in a switch statement.
@@CodesEasy and how can I fix it?
@@xdgogo5231 Well, I also got that error so I converted the switch statements into if-else statements instead.
How to change switch to if statement
@@tnspeedy6444 right click on "switch" and use the context menu to translate the switch to if statements

you type in your code in this arrangement :
android:layout_gravity="center"
android:textStyle="bold"
android:textSize="30sp"
It should be in that order ? Or we can put it in randomly ?
And, does this code work for Android Studio Giraffe ?
You can put it to the element you want to apply these properties, any order is fine
Thanks sir for this video

hello sir thanks for sharing the education, i have question for you, why you use linear layout instead use constraint layout?
imo constraint layout more option for layout, thanks for answer
You can use constraint layout, for this a constraint layout will be a better option too. It's just easier for beginners to understand with linear layout
i see, thank you very much for answer.
it's nice tutorial, keep it work!
sorry but my answers is not showing up in the textview
Check the code, you should have made a mistake
