Data Sync Locally on Device

      Couchbase Lite supports replication between two local databases at the database, scope, or collection level. This allows a Couchbase Lite replicator to store data on secondary storage. It is useful in scenarios when a user’s device is damaged and its data is moved to a different device.

      Example 1. Replication between Local Databases
      // This is an Enterprise feature:
      // the code below will generate a compilation error
      // if it's compiled against CBL Android Community Edition.
      // Note: the target database must already contain the
      //       source collections or the replication will fail.
      final Replicator repl = new Replicator(
          new ReplicatorConfiguration(new DatabaseEndpoint(targetDb))
              .addCollections(srcCollections, null)
      // Start the replicator
      // (be sure to hold a reference somewhere that will prevent it from being GCed)
      thisReplicator = repl;
