Crashlytics says "Received null settings, skipping report submission"

I am trying to switch from Firebase Crash reporting to Firebase Crashlytics.

I have followed the guide here: https://firebase.google.com/docs/crashlytics/upgrade-from-crash-reporting

But during initialization the logs says:

Received null settings, skipping report submission!

And then when testing crashes:

Cannot send reports. Settings are unavailable.

Network connection is good, so no reason why it can't get settings.

Log output:

D/CrashlyticsCore: Initialization marker file created.
W/CrashlyticsCore: Received null settings, skipping report submission!
D/CrashlyticsCore: Initialization marker file removed: true

When upgrading from Fabric Crashlytics to Firebase Crashlytics I found that I needed to make sure that AndroidManifest.xml contained this attribute from Fabric. After having correctly linked the App in Fabric with Firebase. Which you can find at https://www.fabric.io/settings/organizations,

<meta-data
    android:name="io.fabric.ApiKey"
    android:value="..." />

(Replacing ... with your key) This needs to be within the <application> block. Once I included this the settings were detected and crashes appeared in the Firebase console, email alerts.

In my case this same error occurred because i already had forced the crash on the device as required by setup tutorial, for a different flavor of the application.

My App has 2 flavors, so in order to successfully link flavor number 2 i had to force crash on a different simulator.

Note: The 2 flavors need to have different packages at least.

Same happened to me. I had another flavor of the app installed, so I deleted all flavors currently installed and it worked after simulating the crash again.
