App crash on android when activating Debug in RN

[matgardon]

Hi, I'm having a consistent crash when I try to activate Debug from RN dev menu on the bundle pushed onto my device since I added this lib, here are the relevant logcat lines:

Any idea where this might come from ? Weird emulated storage path ?

I can also confirm that removing the reference to MMKV fixes Debug mode.

Debugging an application that uses JSI (that's what this lib uses) with Chrome does not work, same as with reanimated. Flipper debugging should work.

Didn't know this limitation, thanks for the clarification. You can close the issue then, but maybe document this on the README for others to be aware of ? My errors on RN/metro lead me to false tracks & I lost a few hours on this, if I can avoid the trouble for others then I'm happy :-)

FYI this is actually exactly what reanimated did when listing limitations in their docs.

I added a "Limtations" section to the README, thanks :)
