[Android] [DialogModule] IllegalStateException

[grabbou]

Hey,

Again, not sure how to reproduce - ~20 crashes so it's still a super small percentage of overall app install.

IllegalStateException: Can not perform this action after onSaveInstanceState

[mkonicek]

Looks like a bug in the Android Dialog module, in the dismissExisting method.

[mkonicek]

I'll try to find some time to take a look in the next two weeks or so (is that soon enough?). I've refactored the Dialog module when open sourcing it.

[grabbou]

Yeah, or I could look into that as well just to get some Java 🔥

[DoingLiaw]

For reducing crashs,I use the Dialog module that is written by myself.😢

[mkonicek]

@DoingLiaw since you've written your own module, would you be up for sending a bugfix for the React Native one?

We're also seeing this and it's crashing our app on a fairly regular basis. Here's that stack trace if it helps. I don't have much experience with Java otherwise I would contribute a fix:
