Firebase Crashlytics not reporting crashes when manually enabled

Question

Crashlytics works just fine without opt-in reporting. But it stops reporting anything as soon as I set up opt-in reporting according to the tutorial.

Specifically, I added the following content to AndroidManifest.xml

<meta-data
    android:name="firebase_crashlytics_collection_enabled"
    android:value="false" />

And I added the following into the onCreate:

 Fabric.with(this, Crashlytics())

With a debugger, I am sure that the above line has been executed.

However, nothing is reported to the Crashlytics. Instead, the logger gives the following,

D/Fabric: Falling back to Crashlytics key lookup from Manifest
D/Fabric: Falling back to Crashlytics key lookup from Strings
D/Fabric: Generating Crashlytics ApiKey from google_app_id in Strings
D/Fabric: Using AdvertisingInfo from Preference Store
D/Fabric: Falling back to Crashlytics key lookup from Manifest
D/Fabric: Falling back to Crashlytics key lookup from Strings
D/Fabric: Build ID is: ...
D/CrashlyticsCore: Crashlytics is disabled, because data collection is disabled by Firebase.

D/Fabric: Could not get parcel from Google Play Service to capture Advertising limitAdTracking
D/Fabric: AdvertisingInfo not present
D/Fabric: Asychronously getting Advertising Info and storing it to preferences

I have noticed this interesting line: D/CrashlyticsCore: Crashlytics is disabled, because data collection is disabled by Firebase. which is probably the cause of the issue. Yet I can't find any information about this log.

Answer 1

There is an issue with Firebase Crashlytics 2.9.7 preventing opt-in reporting as described in the documentation to work: the start of Crashlytics from code will not be performed. For the time being downgrading to 2.9.6 will enable your code to work properly.

Answer 2

Use following dependencies for android.
Paste it into build.gradle app:

implementation('com.crashlytics.sdk.android:crashlytics:2.9.6@aar') {
transitive = true
}

Upgrade it from 2.9.5 to 2.9.6.
It works for me.
