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.

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.

Cloud Firestore version 17.1.5

  • Cloud Firestore now recovers more quickly from bad network states.
  • Improved performance for reading large collections.
  • Offline persistence now properly records schema downgrades. This is a forward-looking change that allows you to safely downgrade from future SDK versions to this version (v17.1.5). You can already safely downgrade versions now depending on the source version. For example, you can safely downgrade from v17.1.4 to v17.1.2 because there are no schema changes between those versions. Related: https://github.com/firebase/firebase-android-sdk/issues/134

App Indexing version 17.1.0

  • Apps will need to bump their compileSdkVersion to 28 or higher.

  • Added Indexable.Metadata.Builder.setSliceUri(), which gives developers the ability to provide dynamic and interactive search results, Slices, in the Google search app. Note that this method grants permission for the specified Uri to Google Play Services (com.google.android.gms), to bind to and cache the Slice, and to Google search app (com.google.android.googlequicksearchbox), to render the Slice. The client app can revoke Slice permissions to these packages at any time through SliceManager.revokeSlicePermission().

Cloud Firestore version 17.1.1

  • Fixed an issue where the first get() call made after being offline could incorrectly return cached data without attempting to reach the backend.
  • Changed get() to only make one attempt to reach the backend before returning cached data, potentially reducing delays while offline.
  • Fixed an issue that caused Firebase to drop empty objects from calls to set(..., SetOptions.merge()).
  • Updated printf-style templates to ensure that they're compile time constants. Previously, some were influenced by error messages. When those error messages contained %p or other, related tokens, String.format() would throw an exception.
  • Some SDK errors that represent common mistakes, like permission errors or missing indexes, are automatically logged as warnings in addition to being surfaced via the API.

Update - September 18, 2018

SDK Update - May 2, 2018

General

  • Firebase Android SDKs now have independent version numbers, allowing for more frequent, flexible updates.

  • If your app has a dependency on com.google.firebase:firebase-core:15.0.0 as well as any of the following libraries:

    • com.google.android.gms:play-services-analytics
    • com.google.android.gms:play-services-appinvite
    • com.google.android.gms:play-services-tagmanager
    • com.google.firebase:firebase-analytics
    • com.google.firebase:firebase-crash
    • com.google.firebase:firebase-dynamic-links
    • com.google.firebase:firebase-messaging

    You will need to update the version of the latter dependency to 15.0.2. This addresses the issue where version 3.3.0 of the Google Services Gradle plugin reports: The library com.google.android.gms:play-services-measurement-base is being requested by various other libraries at [[15.0.0,15.0.0], [15.0.2,15.0.2]], but resolves to 15.0.2...

Cloud Messaging version 15.0.2

  • Updates for auto-initialization and interoperability with other Firebase libraries.

Cloud Firestore version 16.0.0

  • Replaced the DocumentListenOptions and QueryListenOptions classes with a MetadataChanges enum. Instead of calling addSnapshotListener() with either of those classes, use the enum:
    addSnapshotListener(MetadataChanges.INCLUDE, ...)

  • QuerySnapshot.getDocumentChanges() now optionally takes a MetadataChanges enum. By default, metadata-only document changes are suppressed in getDocumentChanges(), even when listening to a query with MetadataChanges.INCLUDE.

  • Added the ability to control whether DocumentReference.get() and Query.get() should fetch from server only, cache only, or attempt server and fall back to the cache. By default, both methods still attempt server and fall back to the cache.

  • Cloud Firestore no longer ProGuards its dependencies, GRPC and protobuf. As a result, if you use GRPC or protobuf independent of Firestore, your app will now only include one copy of either library in its final APK. If you don't use ProGuard, your app size will increase by roughly 1MB. You can avoid this increase by running ProGuard on your release builds to remove unneeded methods. To learn how, see Shrink Your Code and Resources.

  • Added a ServerTimestampBehavior enum to control how DocumentSnapshots return unresolved server timestamps.

Crash Reporting version 15.0.2

  • Firebase Crash Reporting is now deprecated. To monitor crashes in your apps, migrate to Firebase Crashlytics. To learn how, read Upgrade from Crash Reporting.
