hop of those help? Realm hasn't provided sync feature yet. We are actively working on sync building feature, but we don't have no ETA at the moment.
Easy ways are sharing Realm data file with iCloud or other services. e.g. DropBox API.

Realm Database / App crashes in start up / call realm.init(context) before creating a realm configuration

With these it helps I'm a newbie in Android and I'm trying to create a Realm database by watching tutorials. But my app doesn't start, it crashes. My main idea is the user finds nearby shops, by his location, select type of shop if he wants (restaurant, caffee etc) and if he can't find the shop he wants, the app gives him the option to add a shop (by pin a marker in a map, select a name and a type). In the errors gives me call realm.init(context) before creating a realm configuration Whoever can help I'd appreciate it. This app is my graduation project. I've reached this far; MainScreen.java
code :
public class BaseApplication extends Application{
     @Override
     public void onCreate() {
         super.onCreate();
         Realm.init(this);  // add this line
         RealmConfiguration config = new RealmConfiguration.Builder().build();
         Realm.setDefaultConfiguration(config);
     }
  }

I wish this helpful for you You will need to use multiple joins to the same table - something like:
code :
select user.title as user, pc.title as pc
from nodes as user
join associations as a on a.child=user.id
join nodes as pc on a.parent=pc.id
where user.entity_type = 'User'
select user.title as user, ifnull(nb.title, pc.title) as computer
from nodes as user
join associations as a on a.child=user.id
join nodes as pc on a.parent=pc.id
left join nodes as nb on pc.title='mobile' and nb.id = pc.id + 1
where user.entity_type = 'User'

I think the issue was by ths following , Probably because you're setting the class variable to another Realm, and you have some fairly intricate multi-threading problem going on; nothing to do with device-specificness.
Solution: don't set the class level variable?
code :
public long getPendingImagesCount() {
    try(Realm realm = Realm.getInstance(RealmUtils.getRealmConfiguration())) {
        return realm.where(PatientRecordImage.class).count();
    }
}

I think the issue was by ths following , I would implement a Keycloak plugin based on the EventListenerSpi. In the EventListenerProvider implementation you can concentrate on the user administration events only.
code :
public class SyncEventListener implements EventListenerProvider
{
  private static final List<OperationType> SYNC_OPERATIONS = Arrays.asList(OperationType.CREATE, OperationType.UPDATE, OperationType.DELETE);
  @Override
  public void close() {}

  @Override
  public void onEvent(Event event) {}

  @Override
  public void onEvent(AdminEvent event, boolean includeRepresentation)
  {
    if ((event.getResourceType() == ResourceType.USER) && SYNC_OPERATIONS.contains(event.getOperationType()) )
    {
      // Write user data to external message queue or database
      externalStore.write(event.getOperationType(), event.getRepresentation());
    }
  }
}
