android firebase crashlytics invalid key error

Question

I integrated firebase crashlytics using below url and it was working fine. https://firebase.google.com/docs/crashlytics/get-started?authuser=0

Then I did git pull from other developer and went to build project and got following error:

Error:org.gradle.api.GradleException: Crashlytics Developer Tools error. Error:com.crashlytics.tools.android.exception.PluginException: Crashlytics Developer Tools error. Error:java.lang.IllegalArgumentException: Crashlytics found an invalid API key: null.

Answer 1

I have added this line in end of build.gradle

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

Firebase Crashlytics requires the Google services Gradle plugin (com.google.gms:google-services) in your build script to process the google-services.json file at build time. However, Crashlytics does work on devices that do not have Google Play services.

首先，您必须将Firebase作为https://firebase.google.com/docs/android/setup?authuser=0添加到您的项目中
