Crashlytics troubleshooting and FAQ

Error compiling project with Android Studio plugin

You may get the following error if you try to compile your app with Android Studio 4.1+ while it still contains the legacy Fabric SDK:

Gradle sync failed: No such property: scope for class:
com.android.build.gradle.internal.variant.ApplicationVariantData

Note that the Fabric Gradle plugin (io.fabric.tools:gradle:1.31.2) does not support Android Studio versions 4.1+. If you're using these versions of Android Studio, make sure your app contains the latest version of the Firebase Crashlytics Gradle plugin instead:

1. Make sure your app is using the Firebase Crashlytics SDK. If your build.gradle file contains the legacy Fabric Gradle plugin, your app is likely using the legacy Fabric SDK, which is deprecated and will no longer report crashes starting November 16, 2020. If you haven't already, upgrade to the latest version of the Firebase Crashlytics SDK.

2. As part of Step 2, in your project-level build.gradle file, replace the Fabric Gradle plugin with the Crashlytics Gradle plugin (make sure to use version 2.0.0+):

   ...
   dependencies {
      // ..
   
      classpath "com.android.tools.build:gradle:GRADLE_VERSION"
   
      // Remove the Fabric Gradle plugin.
      classpath 'io.fabric.tools:gradle:1.31.2'
   
      // Add the Crashlytics Gradle plugin.
      classpath 'com.google.firebase:firebase-crashlytics-gradle:2.3.0'
    }
   ...
