[REQUIRED] Step 3: Describe the problem

Just integrated firebase crashlytics into our app. Other services, like analytics and remote config are working fine. Invoking a crash from the app doesn’t show on the firebase console. After investigation I found that there is an issue with writing/reading the log files.

Steps to reproduce:

--------- beginning of main
--------- beginning of system
--------- beginning of crash

Tip: I struggled with this issue when migrating from Fabric Crashlytics to Firebase Crashlytics. Even I could not see my manual Test crash reports in the console.

I believe this is what happens: Earlier Fabric used to always enable the crash collection every time the app opens and had to be explicitly disabled (CrashlyticsCore…Builder…disabled ) when not collecting crashes (say in Debug mode).

While with Firebase Crashlytics, if I disable the crash collection setCrashlyticsCollectionEnabled(false) and then if later I want to enable it, just commenting out the above line DOES NOT automatically start the collection process if the app has already been installed with ‘false’ flag before.

setCrashlyticsCollectionEnabled(true) needs to be explicitly called again!

@mirokolodii If you’ve got a test project set up that reproduces this issue, and can either publish it here on Github or send it through to https://firebase.google.com/support/troubleshooter/contact, that would be very helpful!
