The override now accepts any arguments allowable for org.gradle.api.Project#files(Object...), including java.lang.String, java.io.File, and org.gradle.api.file.FileCollection. You can specify multiple directories for a single build flavor by providing a list or FileCollection instance.

  • The Crashlytics Gradle plugin's dependency on the google-services plugin has been modified to depend on task outputs from google-services rather than depend directly on the google-services task itself. This change (1) resolves a warning that "execution optimizations have been disabled" for MappingFileUploadTask and SymbolFileUploadTask when building with Gradle 7 and (2) makes it easier to override the input for those tasks for apps that don't use the google-services plugin.

  • Modified the Breakpad symbol generator binary to be globally executable and to statically link against standard libraries, which should resolve build errors for NDK developers using Docker-based CI systems.

  • Added getUtmParameters method to PendingDynamicLinkData.

  • Added more instructive error messages to the PhoneAuthOptions.Builder#build() to facilitate easier identification of issues.

  • Fixed a bug that required the inclusion of a browser dependency in the client application. Instead, when Chrome Custom Tabs are not available for web-based flows (such as Generic IDP or reCAPTCHA in Phone Auth), it will fall back to whatever application is the default for the Intent#ACTION_VIEW intent.

The Kotlin extensions library transitively includes the updated firebase-analytics library. The Kotlin extensions library has no additional updates.

Authentication version 20.0.0

  • The Firebase Authentication Android library now works on devices without Google Play services.

  • Added support for the Firebase Authentication emulator. To connect to the emulator, use FirebaseAuth#useEmulator().

    Note that if you're running the Firebase Authentication emulator on "localhost" and connecting from an app that is running inside the Android Emulator, the Firebase Authentication emulator host will be "10.0.2.2" followed by its port.

  • There are several changes to the Phone Authentication & Phone as second-factor flows. The default flows now rely on SafetyNet to do application identity verification, and fall back to a web-based reCAPTCHA flow. For more details about setup, refer to the Phone Authentication getting started guide.

  • Added two methods to help test the other Phone Authentication changes in this release. Call FirebaseAuthSettings#forceRecaptchaFlowForTesting() to disable SafetyNet app verification on phone flows. Call FirebaseAuthSettings#setAppVerificationDisabledForTesting() to disable all app verification on phone flows. Note that disabling app verification will cause flows to fail unless you're using a testing phone number or are connected to the Firebase Authentication emulator.

  • The method PhoneAuthOptions.Builder#setActivity(android.app.Activity) is now required in order to build a PhoneAuthOptions.

  • Removed the method PhoneAuthOptions.Builder#setExecutor(java.util.concurrent.Executor) to accommodate other Phone Authentication changes in this release.

  • Deprecated both versions of PhoneAuthProvider#verifyPhoneNumber() that take an Activity as a parameter.

  • Removed both versions of PhoneAuthProvider#verifyPhoneNumber that take an Executor as a parameter. These removals accommodate other Phone Authentication changes in this release.

The Kotlin extensions library transitively includes the updated firebase-inappmessaging-display library. The Kotlin extensions library has no additional updates.

Firebase Instance ID version 21.0.0

  • The firebase.iid package is now deprecated.

    To retrieve FCM registration tokens, use the equivalent methods in the FirebaseMessaging class. Specifically, call FirebaseMessaging.getToken() instead of FirebaseInstanceId.getToken().

    If you need to identify specific app installations, use the methods in the FirebaseInstallations class to create, access, and delete Firebase installation IDs.

    For more information, refer to the Cloud Messaging v21.0.0 release notes.

  • Removed the auto-initialization functionality and migrated it to Firebase Cloud Messaging. For more information, refer to the Cloud Messaging v21.0.0 release notes.

    This results in a slight behavior change. Before, a call to deleteInstanceId() would automatically generate a new token if auto-initialization was enabled. Now, the new token is only generated on the next app-start or if getToken() is called explicitly.

Performance Monitoring Gradle plugin version 1.3.3

  • Improved overall build time for incremental runs by differentiating processing outputs based on Jar and Directory format.

  • Improved transformation runtime for incremental runs by updating the incremental processing logic for Directory inputs to only process changed files.

  • Fixed the DexMergerException build-time failure (during dex merging) by correctly handling the changed files during incremental processing.

    (IssueTracker #164332661 and IssueTracker #162430661)

  • Fixed the ClassNotFoundException run-time failure (when the app is built on a non-case preserving file system) by updating the transformation logic to process a Jar input to a Jar output instead of extracting a Jar to a Directory (which was overwriting files with similar names but with casing differences).

    (IssueTracker #132840182, IssueTracker #135171107, GitHub Issue Stripe #1139, GitHub Issue Stripe #1141, GitHub Issue Stripe #1476)

  • Fixed the transformed output file names to generate readable names so that they are helpful to later transforms. This was accomplished by using the getName() API provided by the Transform API instead of MD5 hashing the input file path.

  • Improved Task Configuration Avoidance for NDK symbol generation and upload tasks.

  • Improved support for native symbol uploads for NDK libraries that are not built using the standard Android NDK toolchain. For more information, refer to Upload symbols for external dependencies.

  • Fixed a crash that could occur when running the Crashlytics native symbol upload task on a clean build. This was due to a task dependency configuration bug, which also could result in incorrect symbols being generated for some builds.

  • Fixed a bug that prevented the use of absolute paths in the firebaseCrashlytics.strippedNativeLibsDir and firebaseCrashlytics.unstrippedNativeLibsDir extension properties. Absolute paths are now resolved correctly; relative paths are resolved relative to the build file directory. (GitHub Issue #1199)

  • Fixed MissingPropertyException thrown during Crashlytics native symbol generation tasks, when using Android Gradle plugin 4.1.alpha08+.

  • The Crashlytics plugin now throws a GradleException if Crashlytics cannot resolve the app ID generated by the Google Play services plugin, rather than failing silently when attempting to upload mapping and symbol files. The exception message includes information on possible solutions.

  • Fixed the UP-TO-DATE check for the mapping file ID injection task. The task will now be correctly marked UP-TO-DATE if the mapping file ID is not modified.

  • Dropped support for Gradle v4.x and earlier. Customers still using Android Gradle plugin v3.3.2 should update to Gradle 5.0.

To learn if your apps are affected, review the Firebase installations documentation. Also, make sure to monitor FCM registration token generation using the #onNewToken implementation.

    • Apps that use the Firebase auto-initialization process and the Gradle plugin to convert google-services.json into resources are unaffected. However, apps that create their own FirebaseOptions instances must provide a valid API key, Firebase project ID, and application ID.

Firebase Installations version 16.0.0

  • The Firebase installations SDK introduces the Firebase installations API. The Firebase installations service is an infrastructure service used internally by Firebase to identify each installed instance of a Firebase app.

  • Several Firebase products transitively depend on the Firebase installations SDK. Be aware of the following:
