Why is it important to clear the binding in onDestroyView when implementing Android View Binding in a Fragment?

[Nikolay Puliaev]

Because if you won’t clear it memory leak will happen. There are a lot of approaches and even libraries. You can search over google

You may use lazy delegates

[Vivek Modi]

@Nikolay Puliaev do you have better approach

[Vivek Modi]

@Umar Ata how can i achieve that ?

[Umar Ata]

val viewBinding : MyFragmentBinding by lazy {
MyFragmentBinding.inlfate(layoutInflator)
}

@FunkyMuse
Hi
You marked my suggestion as X
Can you please add some details?

[Orhan Tozan]

Easy dropin solution: https://github.com/Zhuinden/fragmentviewbindingdelegate-kt

[Will Shelor]

FunkyMuse didn’t weigh in, but I can- Lazy isn’t Weak, I’m pretty sure that Lazy would still cause a leak.

[Will Shelor]

Unless you never accessed it. Which would kinda defeat the point.

[FunkyMuse]

As Will Shelor said

[Umar Ata]

Do you guys have any documentation for the leak on lazy delegates
I am actually using it and if your statement is true that it also leak so I need to change it in many places
Please provide any documentation that proves your words @FunkyMuse @Will Shelor

Fragments have 2 lifecycles, one for the Fragment itself and one for the View of the Fragment, using Lazy means that your view will be alive as long as your Fragment object is alive
