Android Realm ChangeListener not being triggered

Question

I\'ve got a Realm results change listener that isn\'t being triggered, here\'s the code:

final RealmResults entries = realm.where(LogEntry.cl         


        

Answer 1

You need to keep a class reference to entries to prevent it from being GC'ed:

public MyClass {

  private RealmResults entries;

  public void myMethod() {

    entries = realm.where(LogEntry.class).findAll();
    entries.addChangeListener(new RealmChangeListener>() {
            @Override
            public void onChange(RealmResults results) {
                Log.v("Testing", "The size is: " + results.size());
            }
        });
    }
}
