I tried this and it worked for me.
Add this import in MainApplication.java
import io.realm.react.RealmReactPackage;
also modify getPackages() to

@Override
protected List getPackages() {

  return Arrays.<ReactPackage>asList(

      new MainReactPackage(), new RealmReactPackage ()// this line

  );

}

Can you confirm that you ran rnpm link realm, and that it modified your gradle files along with your MainActivity.java file?

@appden rnpm link realm is ok,but How to modify the gradle files ,my issue for react native

When you run rnpm link realm, it should modify your build.gradle and settings.gradle files along with MainActivity.java. Did they get updated for you? If not, please ensure you have the latest version of Realm (0.13.2) a try running rnpm link realm again. If that still does not work, will you be willing to let me take a look at your project?

I'm getting same error message with Android.
rnpm version 1.9.0
realm 0.14.2

How can I fix this?

(btw: does work with iOS)

@beebase what version of react-native are you running? Did you by chance update your project from an older version? There were some upgrade steps required when updating between some previous RN versions.
