"com.gorisse.thomas.sceneform:sceneform:1.21.0" Freezing

[Tendaman]

I'm developing a simple AR camera using the library "com.gorisse.thomas.sceneform:sceneform:1.21.0", the app seems to work fine until it freezes for seconds then returns normal and freezes again until it crashes. Can someone please provide assistance.

Here is the java code:

do they samples provided from the codebase work ok for you?
we're just scraping by here in this library from a contributor aspect, not much volunteer time available.
if you're interested in being part of the solution, you can

• try and see if you're able to reproduce the issue in any of the samples
• provide a logfile from logcat, detailed device information
• bonus: set up some breakpoints in the sample code to see where things fall apart

as an aside, I turned off depthmode in my codebase. I found it caused device-dependent crashing for me.

I agree with @sameerjj . Just a quick thought, have you tried the most current version of Sceneform Maintained 1.23.0?
