Having trouble with offline sync

Hi,

I've been having some trouble getting offline sync to work in Xamarin.Android with kinvey. I've followed the documentation given here but it doesn't seem to work for me. As long as the phone is online saving data works fine but as soon as I turn off the connection to test offline sync I get the exception:


  

SQLite.Net.NotNullConstraintViolationException: NOT NULL constraint failed: OfflineEntity.id
  at SQLite.Net.PreparedSqlLiteInsertCommand.ExecuteNonQuery (System.Object[] source) [0x0016b] in <filename unknown>:0 
  at SQLite.Net.SQLiteConnection.Insert (System.Object obj, System.String extra, System.Type objType) [0x000bc] in <filename unknown>:0

 Here is the code that is causing the exception:

   

AsyncAppData<Event> events = BackEndService.mKinveyClient.AppData<Event> ("eventCollection", typeof(Event));
events.setOffline (new SQLiteOfflineStore (), OfflinePolicy.ONLINE_FIRST);
try {
    Event saved = await events.SaveAsync(ev);  <----------------exception originates here
    Console.WriteLine (
            "Event: UserId=" + saved.uId);
} catch (Exception e) {
    Console.WriteLine (e + e.StackTrace);   
}

   The mKinveyClient client:

  

public static readonly Client mKinveyClient =
            new Client.Builder(appid, secret)
                .setLogger(delegate(string msg) { Console.WriteLine(msg);})
                .setOfflinePlatform(new SQLitePlatformAndroid())
                .setFilePath(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal))
                .build();

  The Event class:

 

[JsonObject(MemberSerialization.OptIn)]
public class Event {
     [JsonProperty("userId")]
     public string uId { get; set; }
}

 The full exception stack trace:

 I also saw this line a bit further up in the application output just before the exception was thrown:

    [SQLiteLog] (1299) abort at 7 in [insert into "OfflineEntity"("id","json","collection") values (?,?,?)]: NOT NULL constraint failed: OfflineEntity.id

 


I've tried numerous different things to try to fix this but nothing I try is getting me anywhere. It seems like the code is perfectly in line with the documentation but it's generating a constraint exception at the sqlite level of execution. I guess if it doesn't get resolved I'll have to settle for online usage only for now...what a shame.
