I’m only using 1 BlurView and this crash occurs. It’s not related to multiple BlurViews.

brunoaduarte on Sep 16, 2020

same thing with flatlist render items if there is only 1 item it works, otherwise it crashed

I’m only using 1 BlurView and this crash occurs. It’s not related to multiple BlurViews.

Adding to this, I have validated (and I believe it’s something simple to test) that you can have two BlurViews on a single component and not have any crashes.

In my short experience debugging this (which resulted in dropping the library for Android and implementing a workaround using WebView and CSS Blur filters) and looking at the other open issues in the library, these crashes could be related to animations and transitions (for example using inside an Animated.View or in conjunction with React Navigation JS transitions) predating on the same resources that BlurView requires.

This seems a really intensive process for Android and the implementation of the native BlurView library by Dimezis could be too naive for it to work in production environments, since the Blur is performed on the main thread.

But I honestly don’t have the knowledge of native Android development to produce a more insightful comment, just hope this points someone in the right direction.

Same here. Can’t use BlurView as FlatList item…

ezranbayantemur on Aug 31, 2020

I can confirm this bug with a different code path. I am using the BlurView as background in a react-navigation modal navigation screen. When using navigation.replace to open another modal (which also renders a blur view) the app crashes with the same logcat output.

Same here.
