Can you create a video for something like 'Best practices for big apps or advanced apps' to keep them easily readable and updatable with time ?? 🤔🤔

[newbiegameplayy]

Very useful information... If you have a time please make a series for cracking clean Architecture for Android Development. It will be great series for all of us 🙏🏻

You are the best Android and Kotlin teacher I have encountered!! Thank you Phillip...you are literally saving careers out here💯💯💯

[vengateshm]

Excellent. Interview prep material.
Decorator - Modifying an object during runtime.
Eg: Recycler view item decorator

Might look like just another topic. But this is really one of those topics which most developers have no idea about even though they use all these all the time. From my personal experience, this video will save u from embarrassment while attending android interviews. Thanks phlip.

Excellent video, I learned quite a bit about both the patterns in kotlin and gained insight into better ways.
Thanks Phillipp!
I learned these all in Java many years ago... it's so refreshing to see the idiomatic Kotlin versions as well as gain some further insight into each.

As always, unique content.
Thanks man ❤

Dammnnnn phillip, right now I’m doing a test app because I’m applying for an android developer job… and that builder pattern just saved me the day. You don’t know how many hours I was trying to do something in an adapter and this builder pattern was the perfect way to do that. Thank you very much for this video, It came in divine timing

[ibrahimkhalilshakir]

Great job. Please make an e-commerce or Video calling app tutorial 😊

[jaygitonga]

As always great videos Phillip! Do a tutorial on clean architecture or mvi

[akeeaggarwal]

You have made them super easy for us to understand. Thanks man.👍

So a note about the Kotlin way of doing builder, it isn't actually the builder pattern, b/c it doesn't hide the concrete implementation details from the end user. A proper builder pattern can have constructor parameters of the built class change name/order/etc. and not be visible to the end user. However, in the kotlin methodology, you are directly exposing the constructor to the end user. Even with parameter naming, you have an easier chance of making compile breaking changes if you do this vs hiding the details inside the builder.

Simplied and to the point. Good work Philipp 👏

Can you create a video for webrtc for Android?

[ErikBongers]

Having a constructor with default values isn't the best example of a Builder pattern.
A typical Builder should force you to, for example, provide arguments or dependencies in a specific order or a user defined order, or perhaps dissallow a dependency if a previously specified dependency was of a restrictive kind or allow an argument to be given more than once.
In other words, a Builder allows you to restrict argument requirements or give more flexible arguments or a combination of both.
The Modifier is the best example of this. Don't be fooled by it not having this final build() call.

I like the way you teach, so cool. I learnt a lot from you. thanks bro

[ghasemshirdel]

Thanks Philipp, I think some other patterns like Object Pool, Flyweight, Decorator, Observer, Strategy and Proxy has useful in a project

[mkc]

the best time i spend on youtube is seeing your videos

[marerooney]

Another great video Philipp! Thanks for handling some of the advanced topics...
