i love these xamarin and C# tutorials because i already know C# so i don't have to learn any extra unnecessary stuff to develop for android . And thank you for the tutorials.

[@periclesradael]

The best TH-cam tutorial.
O melhor tutorial do TH-cam.

[@kimsann7372]

Could you do about designing interface?
Your tutorials really help me to develop android app

[@user-sp3mx7ck2v]

I really love his tutorial, deserved to call professor ohohoh

[@akompongeric4883]

[@wondwossengebreab5178]

Thank you !

[@deepankardey5935]

good work!!

[@lolikawaii5865]

It works but crashes on my Android 5.1 when I try to perform operations on number/s with dot after pressing equals button.

[@basem902]

thanks

[@albertjjimenezp]

Greetings, can we use unity inside xamarin or vice versa? for example draw mapping routes from google maps api inside a game map in unity. I hope that someone can answer me. Have a nice day

[@dimitridoroshko]

What kind of theme is that? Seems like it's the dark theme, but modified.

[@robertbalassan]

if you start by pressing . app crashes. if you reach the memory limit for number length app crashes. if you randomly tap operator and numbers fast after a time the app crashes. probably those are not the only bugs. found them in 5 seconds after i built it on phone :)) the rest, works indeed exactly the same as the emulator works in the end.

[@Sniperfuchs]

Finally... It took me 40 minutes to figure out that I had set my target to android 8.0 when my phone I was using to debug is 7.1. It always gave me an exception that my ButtonClick method wasn't found and no Google search could help me in any way.

[@ibrahimfares9530]

I have the same problem, how you solved it?

[@debrajmaji1563]

If i type 3+.3 then the app is crashed. Please make a video for fixed this problem.

[@larabatech1200]

amazing !

[@ResoCoder]

Thanks!

[@seylannaidoo8929]

The previous videos were much easier to understand and follow :(

[@edrivenapps5454]

I wish I would not have learned React-Native / Ionic / NativeScript before XM. Seems like A LOT of drama to get simple results. The speed of a XM app seems to be slightly faster....but takes 3x longer to code.

[@GrizzleeSanctus]

thanks! Great tutorial. Can you help me? If click "." without any digit app will close, and any debuging don't help. I try make "If" to add numbers[index] = "0." then value == "." && numbers[index] == null in private void AddDigitOrDecimalPoint(string value) . But app close early :(

[@albertjjimenezp]

i added
if (value == "." && numbers[index] == null)
return;
just before because when csharp search if contains inside a null object throw an exception

[@hunterhalstrom]

I would suggest slowing down a bit.

[@codekotlin1280]

[@ResoCoder]

Xamarin.

[@yourexecutioner3210]

все круто мужик спасибо тебе выручил благослови тебя господь

[@user-sk1uo1ie9z]

can complete this video with the whole functions like sin cos tan pi and others

[@analie1372]

does this have mdas?

[@PranavKumarG]

Does the app has BODMAS operator precedence?

[@ResoCoder]

+Pranav Kumar yup

[@jaistar2364]

i unable to use (Resource.Id.calculator_text_view); because it is not allowing me to type resource.Id

[@TamimProduction]

Hi! write copy this : calculatorText = FindViewById(Resource.Id.calculator_text_view);

[@peterszilagyi6712]

My application dont work. :/

[@KhoJee17]

why can't I run the app, I've done every single thing you've said, why is this?

[@kevinromero8813]

what does it tell you when you try running it?

[@ninja_wolf-9k330]

Hay bro anyone can do that so simple like this
//Called when application is started.
function OnStart()
{
//Create a layout with objects vertically centered.
lay = app.CreateLayout( "linear", "VCenter,FillXY" );
//Create text label
txt = app.CreateText( "type a term!" );
txt.SetTextSize( 30 );
lay.AddChild( txt );
//Create text edit box
edt = app.CreateTextEdit( '', .5, -1, "Singleline" );
edt.SetOnChange( calculate );
lay.AddChild( edt );
//Add layout to app.
app.AddLayout( lay );
}
//calculate term
function calculate() {
//get term and remove all spaces
var term = edt.GetText().replace(/ /g, "" );
//try to calculate term and handle errors
try {
//handle empty term
if( term == "" ) txt.SetText( "type a term!" );
else txt.SetText( eval( term ) );
} catch(e) {}
}

[@ResoCoder]

Hello, would this actually work? You're creating the layout programmatically and such... May I ask what programming language is this written in? Javascript?
