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...

Analytics version 15.0.2

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

Authentication version 15.1.0

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

  • Added the updateCurrentUser() method to the FirebaseAuth class, to allow copying FirebaseUser s from one instance to another.

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 DocumentSnapshot s 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 .

Cloud Storage version 15.0.2

Cloud Firestore

  • Firestore now cleanly shuts down idle write streams.
  • When the includeMetadataChanges option is enabled, snapshot listeners now receive an event, withsnapshot.metadata.isFromCache , if the SDK loses or regains its connection to the backend. The event is true when the connection is lost and false when it's regained.
  • DocumentSnapshot.getData() now returns null instead of throwing an exception when you use the method on non-existant documents. If you'd like to minimize number of null-checks in your code, use the new QueryDocumentSnapshot class instead.
  • Added the disableNetwork() and enableNetwork() methods to the FirebaseFirestore class, allowing for explicit network management.
  • Firestore queries can now accept Timestamp as an argument.
  • Fixed a regression that sometimes resulted in an "OnlineState could not affect limbo documents" assertion crash when a client lost its network connection.
