I finished setting up my firebase project and implement some of the features including FCM and crashlytics but when I’m trying to set up my first crash so dashboard can detect it, nothing happens and when I’m checking my application Logcat something like this error appears first run of application after crash:

I’m sure everything is done as it must, step by step according to documents. But what’s wrong? what’s the solution?

PS: FCM working perfectly so project is set correctly. but crashlytics is not working.
