Returns theFirebase.FirebaseApp instance to which thisFirebaseDatabase belongs.

Gets the instance ofFirebaseDatabase for the default Firebase.App.

AFirebaseDatabase instance.

By default, this is set toInfo This includes any internal errors (Error ) and any security debug messages (Info ) that the client receives.

Set toDebug to turn on the diagnostic logging.

On Android this can only be set before any operations have been performed with the object.

The desired minimum log level

Gets aDatabaseReference for the root location of thisFirebaseDatabase.

ADatabaseReference instance.

Gets an instance ofFirebaseDatabase for a specificFirebase.FirebaseApp.

Gets an instance ofFirebaseDatabase for the specified URL.

Gets aFirebaseDatabase instance for the specified URL, using the specified FirebsaeApp.

Gets aDatabaseReference for the provided path.

Gets aDatabaseReference for the provided URL.

Gets aDatabaseReference for the provided URL. The URL must be a URL to a path within thisFirebaseDatabase. To create aDatabaseReference to a different database, create aFirebase.FirebaseApp with aFirebase.FirebaseOptions

object configured with the appropriate database URL.

Shuts down our connection to theFirebaseDatabase backend untilGoOnline() is called.

Resumes our connection to theFirebaseDatabase backend after a previousGoOffline() Call.

TheFirebaseDatabase client automatically queues writes and sends them to the server at the earliest opportunity, depending on network connectivity.

TheFirebaseDatabase client automatically queues writes and sends them to the server at the earliest opportunity, depending on network connectivity. In some cases (e.g. offline usage) there may be a large number of writes waiting to be sent. Calling this method will purge all outstanding writes so they are abandoned. All writes will be purged, including transactions andDatabaseReference.OnDisconnect() writes. The writes will be rolled back locally, perhaps triggering events for affected event listeners, and the client will not (re-)send them to theFirebase backend.

Sets whether pending write data will persist between application exits.

TheFirebaseDatabase client will cache synchronized data and keep track of all writes you've initiated while your application is running. It seamlessly handles intermittent network connections and re-sends write operations when the network connection is restored. However by default your write operations and cached data are only stored in-memory and will be lost when your app restarts. By setting this value to true, the data will be persisted to on-device (disk) storage and will thus be available again when the app is restarted (even when there is no network connectivity at that time).

Note:SetPersistenceEnabled should be called before creating any instances ofDatabaseReference, and only needs to be called once per application.
