Android - Firebase Crashlytics - "Failed to retrieve settings"

Question

I have troubles making Firebase crash reporting send logs to firebase (Can't see any crashes in firebase console)

I found that previously I've created project in Fabric Crashlytics and removed it today

As far as I know I have configured my android project properly. So maybe I'm just missing something in firebase console. Code is successfully compiled and Fabric.isInitialized() == true

project -> build.gradle

   classpath 'com.google.gms:google-services:4.2.0'
   classpath 'io.fabric.tools:gradle:1.28.1'

app -> build.gradle

implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.crashlytics.sdk.android:crashlytics:2.9.9'

apply plugin: 'com.google.gms.google-services'

No <meta-data> in manifest and no Fabric.with in Application. So clear configuration. Project itself is however pretty huge.

After invoking crash using Crashlytics.getInstance().crash() this is output in console using adb logcat -s Fabric CrashlyticsCore

I CrashlyticsCore: Initializing Crashlytics 2.6.8.32
E Fabric  : Failed to retrieve settings from https://settings.crashlytics.com/spi/v2/platforms/android/apps/*******/settings
W CrashlyticsCore: Received null settings, skipping report submission!

So main problem is probably I'm not receiving settings and have no idea what that means

Answer 1

This is dumb but someone may have the same issue:

I had a proxy running while I was debugging, so the emulator couldn't reach the Firebase servers.

Configuring the proxy/emulator correctly fixed the problem

Answer 2

I just want to add this in case someone has this issu. I was getting the Failed to retrieve settings .... error despite Dashboard working. Turns out you have to enable Crashlytics. I had another app on the same project so it wasn't showing me the enable button until I switched to that app.
