Crashlytics found an invalid API key - AndroidStudio build

Question

I saw all other questions, but none of accepted answers is working for me.

By following integration steps found here https://dev.twitter.com/twitter-kit/android/int

Answer 1

I also experienced this issue and it took a while for me to realize I forgot adding the following line into the app/build.gradle:

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

After adding it, it started working like a charm even without <meta-data> in manifest and/or app/fabric.properties file.

Answer 2

Works fine added this on fabric.properties like this:

# Fabric properties file: app/fabric.properties
apiSecret=xx68f6074dxxxxxc11dxxx97c172e8ebf0
apiKey=xxxe76c4xxxx97e8cxxxx0135e9d46f5a2xxx

Add on .gitignore (for open source projects)

REMOVE entry on AndroidManifest.xml:

<meta-data
    android:name="io.fabric.ApiKey"
    android:value="xxx6c41xxx6ec601xxxd4xxxa2" />

Answer 3

You just forgot to add one line, in app-level gradle file.

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

this happens because when you are adding firebase:crashlytics, firebase document not have this line. so you need to add it manually. see this is firebase:crashlytics document photo.

Answer 4

after adding file fabric.properties, getting error as below.

Crashlytics found an invalid API key: null. Check the Crashlytics plugin to make sure that the application has been added successfully! Contact support@fabric.io for assistance.

We need to register app and verify SHA-1 for same. Add firebase: add google-services.json file from firebase console to your /app folder of your application.(follow steps given by Firebase Console-> Add Firebase to your Android app ) It's not giving error now

Answer 5

This happened to me when I updated Android Studio from 3.2 to 3.3, to fix it I just updated the

classpath 'com.google.gms:google-services:4.1.0'

to

classpath 'com.google.gms:google-services:4.2.0' 

And it worked again

Answer 6

<meta-data android:name="com.crashlytics.ApiKey" 
           android:value="YOUR_API_KEY"/>

Add this one on Android manifest.xml here you get the api key https://www.fabric.io/kits/android/crashlytics/install
