Where does Crashlytics.log(""); go?

Question

I'm trying to set up my app with firebase+crashlytics for having a better error dashboard.

All the firebase stuff is already working and I'm able to access the features

I tested crashlytics with: Crashlytics.getInstance().crash(); // Force a crash
and i'm able to see the stack trace on my dashboard (inside firebase)

but I'm trying to log non-fatal messages like:
Crashlytics.log("test");

And it doesn't appear anywhere I followed the whole instructions at:
https://firebase.google.com/docs/crashlytics/customize-crash-reports

Still doesn't find any dashboard with the "test" messages

Where does it go? what am I missing?

Answer 1

Sending non-debug errors (e.g. your test message) logs to Crashlytics locally, but these exceptions are not uploaded until the app restarts.

As the documentation states:

Crashlytics batches logged exceptions together and sends them the next time the app launches.

This is presumably due to the primary Crashlytics functionality (reporting crashes) working in the same way, and non-fatal errors being a secondary concern using the same code flow.

Whilst this is unfortunate, there are many third party log-collating services that can handle the non-fatal errors.

Note: I'm aware you've received an answer in the comments from Crashlytics, I'm providing a more comprehensive answer for future visitors.
