I think your main problem is in the Realm initialization. You should have an application class and initialize your Realm in there. Like this:
public class BaseApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
Realm.init(this);
RealmConfiguration config = new RealmConfiguration.Builder().build();
Realm.setDefaultConfiguration(config);
}
}
And then you can call my_realm = Realm.getDefaultInstance();
I hope this solves your problem.
