What is the “weak global reference table”?

Question

After playing a video in the WebView on Android for a bit I get this crash. I'm sure I'm doing something wrong on my end since I can't reproduce it on other WebView browsers but first I want to understand what the weak global reference table is? is it for WeakRerefence instances?

Thanks.

Edit: Just to be clear, I've seen a few answers about the global reference table but not about the global reference table . global reference table答案。

Edit: it appears that the crash only happens while the app is being debugged.

Answer 1

Quoted from Stephen Nelson

Your code is failing because you have too many global references to objects that have not been released back into the memory pool

Here is the link to the link for the full answer Why do I need to release global references created in JNI native functions?
