    Caught Signal

    Can anyone tell me what a caught signal is (no number given) and why it might be crashing my Android build?

    Hi Cameron_K,

    A signal is a way to communicate between processes. Here the signal is probably interpreted as an error occurring in Google AR Core. You should find more details in AR Core documentation.

    Cheers!
