Getting Fatal Error on Sync in 2.0 and as well as in 2.1

Mobile Couchbase Lite
1

@priya.rajagopal @jens @pasin It’s been a whole year I am getting the same issue. I am still working on couchbase lite 1.6. I am unable to move on 2.1. Every time it crashes whenever I start sync methods. I am trying to sync four different buckets from server to couchbase mobile. Every time I am getting this same fatal error. Please help me what I am doing wrong over here.

I have written a replication method over application class. Is this creating an issue? Or do I need to run this replication function in threads?

public void startReplication(Database database) {

URI uri;
try {
    uri = new URI(PATIENT_PRESCRIPTION_SYNC_URL);
} catch (URISyntaxException e) {
    e.printStackTrace();
    return;
}
if (!SharedPrefrenceUtils.loadSavedPreferences(context, SharedPrefrenceUtils.doctorId, "").equalsIgnoreCase("")) {
    ArrayList<String> channelList = new ArrayList<>();
    channelList.add(SharedPrefrenceUtils.loadSavedPreferences(context, SharedPrefrenceUtils.doctorId, ""));
    if (channelList.size() > 0) {
        Endpoint endpoint = new URLEndpoint(uri);
        ReplicatorConfiguration config = new ReplicatorConfiguration(database, endpoint);
        config.setReplicatorType(ReplicatorConfiguration.ReplicatorType.PUSH_AND_PULL);
        config.setChannels(channelList);
        config.setContinuous(true);

        // authentication

        replicator = new Replicator(config);
        replicator.start();
    }
}
}

I need a serious help on this. Its been whole one year I am facing the same issue.

From the logs, it does not appear to be the same issue that was posted earlier . In the earlier case, it was a connectivity issue (ENETUNREACH ) . I don’t see any of those messages here.
Please file a bug ticket on the Android GitHub repo with all the relevant details -

  • Library Version
    – What version of the library is installed on your project

  • Operating System / Device Details
    – The OS of your DEPLOYMENT device

  • Log Output
    –Full stack trace . preferably as a gist if its too long

  • Expected behavior
    – What should have happened? Sometimes differing expectations are the cause of the issue

  • Actual behavior
    – What happened instead?

  • Steps To Reproduce
    – Please be as specific as possible, as if you needed to write an algorithm that performed the task

  • Reproduction Project
    – Please attach a project that reproduces the behavior quickly and reliably. This is optional,
    but it very greatly speeds up the time it takes to resolve the issue.

Please file the ticket on the appropriate GitHub repo as suggested. If you have already done so, then we can just track it there and avoid duplicate channels of communication.
