A couple of things that helped me understand this video a bit better:
1) doing the fella's crash course and building a couple of command line apps
2) don't copy exactly what he is doing. Make an app with a similar concept (e.g. an app a waiter would use to note down food / drink orders) change the variable names and the names of the files, this way you have to figure out what is going on. The more different you can make it while keeping the same basic elements, the more it will make sense to you after building it

You lost me when you started making TodoAdapter Class, it's so wierdly complex.

[tapiohonkanen]

In my opinion it would be more educational, if you showed how the app works part by part in the emulator instead of coding everything at once and showing the end result just at the end. Otherwise, very good tutorial!

[noodle-eater]

Awesome, simple tutorial yet have the full features of a todo app. can't wait to try it.

Thank you for your videos. I've been struggling to find good kotlin tutorials, until I found this channel. You're very clear, to the point, and I understand it when you explain it. I come from a long, strictly Python background and the transition isn't easy.

[ArifBillahOnGoogle]

I don't know why, but I feel like android development is extremely complex unnecessarily compared to web development. You have to write so much code to print so little.

You dont really explain what a lot of the functions do after the half point of the video. Theres also a major issue at 47:40 where you cant continue to follow along because it wont let you link tvTodo and the other var

[yiyou]

Finished! Great video, thank you Philipp

[RedTree]

Thank you so much for explaining the logic again at the end!!

[sylvainfinette]

Great video! at the minute 47:12, my editor does not detect the tvTodoTitle nore cbDone objects defined in the item_todo.xml, because of this I cannot complete the apply function. Any idea about what I missed? (I am an absolute beginner)

[mihirraval]

Thank you, this video was a big help to get a refresher on implementing recyclerview with Add, Delete operations in kotlin.

Very nice, very easy to understand for those who interacting with Android Dev for the first time, of course u have to listen to what he said so you can understand it, not to skip the session

[maryannadelman]

Philipp, do you plan to make a video showing how to connect this todo list with a database so that items that are added to the list are retained when the app is closed and reopened?

"of course we will use the Dark Theme here" -> me hitting thumbs up!

[captalextamonan]

Mant thanks for this video. Latest one so far, it worked with AS beta 4.2, just a few updates, Excellent work

[vishnupradhaban]

I am new to android development. I have been searching for good tutorials for the same. And I found this. It's really helpful.

[ussamakhelfa]

Great one .. keep doing this .. that's will make stronger and halp others to love more what they really wanted to love doing .. u just remind me of what a big part of me wanted to always been .. thank you for that ..

[ichigokurasaki_]

The way he so said "**Of course** we will choose the dark theme here." so confidently :D

[stephentellez]
