Monitoring the replication process on CouchDB

I have a project with CouchDB and couchbase-lite on Android. I have an Activitiy ,lets say ReplicationActivity, where I am showing a ProgressDialog while the replication process run, this process uses around 2 hours. My plan is when the replication process is finished the app moves the user to the MainActivity.
The problem I have is that the app moves to MainActivity before the process is finished, so I have not all the data available on MainActivity

In order to monitoring the replication process I am doing this:

CouchbaseManager.getInstance().addProgressListener(new Replication.ChangeListener() {
        @Override
        public void changed(Replication.ChangeEvent event) {

            if (CouchbaseManager.getInstance().getReplicationProgress() > 0 &&
                    CouchbaseManager.getInstance().getReplicationTotal() > 0 &&
                    CouchbaseManager.getInstance().getReplicationTotal() ==
                    CouchbaseManager.getInstance().getReplicationProgress() &&
                    CouchbaseManager.getInstance().getPullwork().getStatus() !=
                            Replication.ReplicationStatus.REPLICATION_ACTIVE &&
                    CouchbaseManager.getInstance().getPushwork().getStatus() !=
                            Replication.ReplicationStatus.REPLICATION_ACTIVE &&
                    CouchbaseManager.getInstance().getPullmaster().getStatus() !=
                            Replication.ReplicationStatus.REPLICATION_ACTIVE) {
                if (mProgressDialog != null && mProgressDialog.isShowing()) {
                    mProgressDialog.dismiss();
                    Log.i("usercontroller", "MOVING TO MAIN ACTIVITY");


                }

Any idea about what I can do in order to know the when replication process is finished?

You want to look at the ChangeEvent object passed to the listener.

Here's an example on how to detect a replication finishing:

// Replication.ChangeListener
@Override
public void changed(Replication.ChangeEvent changeEvent) {
  if (changeEvent.getError() != null) {
    Throwable lastError = changeEvent.getError();

    // React to the error

    return;
  }

  if (changeEvent.getTransition() == null) return;

  ReplicationState dest = changeEvent.getTransition().getDestination();

  replicationActive = ((dest == ReplicationState.STOPPING || dest == ReplicationState.STOPPED) ? false : true);

  stateListeners.forEach(listener -> listener.onChange(replicationActive));
}

You can find more background and discussion of the code in this blog.
