I forgot to mention in this video that you should also destroy your binding in the onDestroy() function. For that, simply make it nullable and set it to null in onDestroy

[@samirbasnet9523]

Hey Phillip great video, can you please explain why do we need to destroy the binding?

[@derpizzaboi]

@@samirbasnet9523 i am not 100% shure, but i think the problem is that if you rotate your device, the view gets destroyed. if your rotated view is the same as the one before you dont have a problem. But if you have two diffrent views for portrait and landscape mode, you will get a null pointer exception because the view that is still stored in the binding variable is not on the screen anymore

[@nousernamethx]

@@samirbasnet9523 Fragments outlive their views. Make sure you clean up any references to the binding class instance in the fragment's onDestroyView() method.(taken from developers.android site)

[@pratikmaurya7394]

@Dark Sigma Yes you can, and remember to use the double bang '!!' operator whenever referencing like binding!!.tvHelloWorld.text = "View Binding in Fragments"

Awesome tutorial with examples, I wish more tutorials would add Kotlin/Java in the title though. Haven't started learning Kotlin yet but still a good watch to understand the flow of binding

[@parthpatel8173]

Personal Suggestion: Please use ViewBinding & DataBinding in your upcoming tutorials. So, it will be more clear to how can we use it in real projects.

[@PhilippLackner]

Only in the projects, not in these single tutorial, that just takes too long to setup everytime if I just make a 10min video

[@aginamabednego]

Thank you once again. Straight to the point

[@brianquigley1940]

So... "binding" puts the physical address of a variable/view (their location in memory) in a variable? You then reference that area of memory? Or reference an offset to a part of that location in memor? e.g. root points to the base address and a textview points to its offset from that base address. Did I get this right?

What's your opinion on DataBinding? is it recommended? i don't see you using it in your tutorials

[@aekazakgmail]

Thank you Philipp! Nice to see your face in video! Great style! I don’t like this new coding style with binding.textview1.... binding.button1... binding.whateverElse... Looks like as everything I can see is binding binding binding )) It drives me mad a little bit. So I renamed ‘binding’ class to just ‘b’. Works fine! Now I can see in my code: b.textview1.... b.button1... b.whateverElse... Looks much better for me! Keep it going, Philipp!

Just because jetpack compose will be out doesn't mean you don't need to understand XML. There will be SO MUCH legacy code in the internet and especially companies can't just casually switch to compose if they have big apps using XML. Also, it'll take some time till compose is stable and not in alpha anymore
