Firebase Crashlytics not reporting crashes when manually enabled

问题

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/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.

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.

For those wish to use crashlytics for their android app who haven't been using crashlytics of fiber.io, there are certain changes in the way you FirebaseApp is initialized which you will find in the above link.

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.

Add this line into Application class

Fabric.with(this, Crashlytics())

Crashlytics 2.9.8 has been released which fixes the bug. I've tested to confirm. The changelog:

2.9.8 December 21, 2018

• Fixed bug with firebase_crashlytics_collection_enabled flag that erroneously disabled data collection under some circumstances.
