Crashlytics found an invalid API key - AndroidStudio build
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.
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
Works fine added this on fabric.properties like this:
# Fabric properties file: app/fabric.propertiesapiSecret=xx68f6074dxxxxxc11dxxx97c172e8ebf0apiKey=xxxe76c4xxxx97e8cxxxx0135e9d46f5a2xxxAdd on .gitignore (for open source projects)
REMOVE entry on AndroidManifest.xml:
<meta-data android:name="io.fabric.ApiKey" android:value="xxx6c41xxx6ec601xxxd4xxxa2" />Oficial documentation: https://docs.fabric.io/android/fabric/settings/working-in-teams.html
