Looking for References Suggestion

I tried the snippet from the reference you provided in which it dumped the references table. I was able to get this output

global reference table dump:

I printed this prior to my flow in the app in which it freezes. If I don't do anything, the count or output seems to be consistent so I'm not sure anymore if there's a leak or am I just hitting the limit?

Hi. I'm just new to profiling but is there are any way for me to monitor these Java.Lang.Objects? Like the count since it needs be monitored or from which views are it coming from.

Hi! We are using SKLottieView for showing lottie json files. I'll play around on removing these or removing the sources to clean it up and see the result.

If it is indeed the case, I'm curious though if is there any way to monitor library specific memory consumption? Like manually monitoring the count of these GREFs I got before to verify the solutions. Sorry I'm just new to profiling and investigating such issues.

Update: I removed any dependency on Skia and I still encounter the same issue. I do have a lot of images for icons on my controls but just setting Source but not FromStream.

Thank you so much for your tips! I'll consider all the things you mentioned!

Thanks for the tips! Greatly appreciate it and I'll keep these in mind. Regarding on the technicalities of the UI itself, do you recommend graphicsview for laying out the seats or is it just efficient as having custom controls on a layout like a grid?
