There is a issue if use both realm-java and realm-js

In my android app, I use both realm-java and realm-js. After I created a object in reaml-java, then I query it in react-native with realm-js, but I get null.

This is my code:

// create a Baby object
Realm realm = Realm.getDefaultInstance();

Baby baby = new Baby();
baby.name = "Baby Name";

realm.beginTransaction();
realm.copyToRealm(baby);
realm.commitTransaction();

// then query in react-native
let baby = realm.objects('Baby').filtered('name = "Baby Name"')[0];
// but the result of baby is undefined

It won’t get the result until I reload react-native JS. But I debug in chrome with stetho_realm, I can see the object has been created.

I don’t know whether it’s a bug, or maybe there is a error in my code. But that’s OK in my ios app with using both realm-swift and realm-js.

My environment are:

Mac OS 10.11 Android 5.1 node 5.3 realm-js 0.11.1 java version “1.8.0_66” io.realm:realm-gradle-plugin:0.88.2

FWIW, I found the following workaround to be effective:

1. Add a java-side event that’s fired into the javascript side when the realm changes (via io.realm.Realm.addChangeListener or io.realm.DynamicRealm.addChangeListener).
2. Debounce change events on the javascript side and do an empty write() on the realm for it to update.

I’m still getting this issue. I created a new React Native project and installed realm via npm (it installed version 1.12.0 of the realm npm module). On the Android side of things I’m using version 3.7.2 via the realm gradle plugin. I can add an object on the Android side of things but I only see an updated object count in RN if I use @wusuopu’s method of executing an empty write. The problem with that is that the count is alway one behind the actual count. I see this appears to be fixed so am wondering is there something I’m missing in order for my change listener to see changes made via Java?
