Crashlytics found an invalid API key - AndroidStud

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/integrate I have created crashlytics.properties file in module root. File is filled with apiKey and apiSecret values found in my newly created twitter application.

Error occurr on project build. I am using AndroidStudio 1.0

This is my error:

ERROR - Crashlytics Developer Tools error.
java.lang.IllegalArgumentException: Crashlytics found an invalid API key: REAL_APIKEY_VALUE. 
Check the Crashlytics plugin to make sure that the application has been added successfully!

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 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" />
