Thanks for this update! Im also one of your student in android master class. Though I haven't finished all the projects yet but now I building already my own simple app.

[@marcosbigbrown472]

Please my greatest teacher, I am one of your students in udemy master class, and all we build was with kotlinx extension. Now the view binding is here, we are going to implement it and rebuild the apps ourselves. Thanks. But I plead with you to please prepare a lecture on chatting app for us. It's my greatest pleasures learning under you sir. Thanks and God bless

[@dewetvanrooyen8458]

My Hero , thanks a million . I was using the findviewbyid what a pain that was.

[@yogeshmishra6025]

Hi Denise, thanks for this video, just to let you know google now does not allow to publish an app using this deprecated synthetic library, i made my entire app using the same and now i have change it to use binding

[@Blackops1990]

Works for me thx. back to the master class ;)

Muy buen video, me ayudo en resolver un dilema que tenia, estoy aprendiendo a programar el kotlin y fue de mucha ayuda gracias :D/ Very good video, it helped me to solve a dilemma I had, I am learning to program the kotlin and it was very helpful thanks : D

[@davidfields11576]

Denis, I'm trying to convert all the class projects over to use View Binding the new method and I'm having an issue in the following line: binding = ActivityMainBinding.inflate(LayoutInflator) the LayoutInflator is underlined in red and throwing the error in Studio v4.1.1 I have made all the other changes as required per your instructions The error says the following: Function invocation 'LayoutInflater(...)' expected None of the following functions can be called with the arguments supplied. (Context!) defined in android.view.LayoutInflater (LayoutInflater!, Context!) defined in android.view.LayoutInflater

[@davidfields11576]

OK, I found my mistake with this, the layoutinflater is supposed to start in lowercase L not uppercase L, so its supposed to be "binding = ActivityMainBinding.inflate(layoutInflater)" It looked like uppercase L in the video - hope that helps someone

@@davidfields11576 Thank you this comment helped me

[@doublem524]

Thanks! This was the solution I was looking for!

[@tomlemes]

omg, after all these years, I can still get caught by a simple error like this!! Thank you David :)

[@nkumaratech]

@@davidfields11576 I was just about to quit... it looked like a capital L. Need to keep code font as Arial or Times New Roman hahaha

[@alecprologg]

Binding works with includes as well 👍🏻

[@jazzalchemy2]

I'm taking your "The Complete Android 10 & Kotlin Development Masterclass" and this video comes up very early in the course, but I can't get the "best practice" code suggested (binding) to work.

Same problem here. This video mentions "binding.myTV.text" wich is not included in the masterclass.

Is there any way to control a button from another activity? For example if I am in the Main Activity and here I have functions which are necessary for me and also if there is another activity called as MainActivity2 and it has a Button and if I want to click this Button in MainActivity(not its own activity) because that functions necessary in this point. What should I do ? is it possible ?

Hi please I have this message display while I was trying to sync ( failed to resolve: com. google ) please how can I solve it? Thanks

[@AryanvedhFromIndia]

if i still want to use kotlin-android-extensions, is there a way to set it by default? so i don't have to add dependencies in Gradle file in every project? thanks

[@Nchernishov]

sir, i am beginner, so you saved my ass!

[@RomskieL]

I just noticed that if I use underscore in the UI element ID example id/btn_start, when accessed using binding it becomes camel case btnStart.

[@tutorialsEU]

sweet. Thanks for the info. Never tried it :)

[@thepatlagoon]

How would I do the btn_start with the binding method for the quiz app?

[@RomskieL]

@@thepatlagoon if your id is btn_start then you can access it in viewbinding as binding.btnStart

[@Wayofthelao]

I'm having some difficulties getting my first build to work and I can't get any response from anyone on the Q and A on the udemy course

[@marcelwo4jedynki]

thank you so much!

[@dennisbaumann2708]

Hey Denis, with the new android studio version some things seem like they doesnt work like this anymore... I can't get my btn_start and et_name ID's to work properly... Do you have any idea?

[@tutorialsEU]

Which of the three approaches are you trying?

[@murml]

Got an error "e: [...]\example\erstesprojekt\MainActivity.kt: (18, 47): Function invocation 'LayoutInflater(...)' expected" in line "binding = ActivityMainBinding.inflate(LayoutInflater)" if I try this for Lesson 15 of the Masterclass-Course. Anyone can help? Did it like shown in this video here. Used the binding method of course.

[@murml]

Found the problem: there seems to be a difference between LayoutInflater and layoutInflater (upper/lower case). Lower works, if someone else got the same problem. Why this is so i cannot explain.

[@nullnull9506]

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.currencyapp/com.example.currencyapp.MainActivity}: java.lang.NullPointerException: rv_home must not be null ================= Please, what is the cause of this error

[@gappergob6169]

Nice! Could you make video about custom view and compound view. There's not much video about that on youtube. Thanks 😊

[@tutorialsEU]

Thanks for the input. I will look into that.

When I uses ADB :This error is coming The ADB binary found at C: \Users\hp\AppData\Local\Android\Sdk\platform tools\adb.exe is obsolete and has seriousperformance problems with the Android Emulator. Please update to a newer version to get significantly faster app/file transfer. Never show this again. OK Help please

[@darrellleong4780]

LayoutInflator doesn't work anymore. It requires some kind of context.

[@jazzalchemy2]

The only one of these 3 versions that seems to work for me is the one that uses the following lines of code... In build.gradle : id 'kotlin-android-extensions' In MainActivity: import kotlinx.android.synthetic.main.activity_main.* class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) //val my.TV = findViewById(R.id.myTV) myTV.text = "Hola Muchachos!" Everything else fails.

[@thinktank4070]

this update is also outdated now how to resolve this??

[@zuhairbilal2222]

It shows an error :-- Plugin was not found in any of the following sources :

[@abdurrahman_z]

me too

[@Revitalish]

The second approach, where need to add the line in gradle and then it should automatically suggest to import the right class in the activity - DOESN'T WORK in Android Studio Arctic Fox :( too bad, looks like the simplest approach

[@lanchesternaanyane]

Can’t believe I actually understood this!😭

Aha! That is why your example code did not work (just a small part of it anyway). thanks!

The course is out of date and befor you get to know that most of the code are not working you cannot also get refund
