How to load react native JS bundle from network in Android?

1.download bundle file(s) and manage the path(s).

2.new a ReactNativeHost in your Application:

public String mBundleFilePath = "";
private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
    @Override
    protected boolean getUseDeveloperSupport() {
        return BuildConfig.DEBUG;
    }

    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.asList(new MainReactPackage(), new MyReactPackage());
    }

    @Override
    protected String getJSBundleFile() {
        return mBundleFilePath;
    }
};

3.before starting a ReactActivity, assign the path of ur bundle file to variable: mBundleFilePath.

public class ReactNativeActivity extends ReactActivity {
    public static void launchSelf(...) {
        MyApplication.getInstance().mBundleFilePath = path;
        COMPONENT_NAME = ...;
        Intent intent = new Intent(activity,ReactNativeActivity.class);
        activity.startActivity(..);
    }
    ...
}

Yes, it's possible. you can give Code Push a try(but their android version not stable yet), or find out how to do that in their code.
