Does react-native-video work with react-native-navigation

Question

I'm trying to get videos to play in my react native app. I'm trying to use react-native-video but when running the app via react-native run-android I get the error message:

"undefined is not an object (evaluating'_reactNative.NativeModules.UIManager.RCT Video.Constants')

This message doesn't really tell me much, but after trying to get this to work for a while I started to suspect that react-native-navigation, , which is the navigation I use for my app, has something to do with it. So I created a new react-native project and added react-native-video to it and got it working without too much trouble.

So my question is if anyone has experienced the same thing, and could provide a solution to getting these two packages working together?

My settings.gradle:

rootProject.name = 'newproj'
include ':react-native-video'
project(':react-native-video').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-video/android')

include ':app'
include ':react-native-navigation'
project(':react-native-navigation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-navigation/android/app/')

build.gradle Module react-native-video

apply plugin: 'com.android.library'

android {
    compileSdkVersion 23
    buildToolsVersion '25.0.1'

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
}

dependencies {
    provided 'com.facebook.react:react-native:+'
    compile 'com.yqritc:android-scalablevideoview:1.0.1'
}

dependencies in build.grade Module: app

dependencies {
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.facebook.react:react-native:+"  // From node_modules
    compile project(':react-native-navigation')
    compile project(':react-native-video')
}

MainApplication.java

import android.app.Application;

import com.facebook.react.ReactApplication;
import com.brentvatne.react.ReactVideoPackage;
import com.facebook.react.ReactNativeHost;
import com.facebook.react.ReactPackage;
import com.facebook.react.shell.MainReactPackage;
import com.facebook.soloader.SoLoader;
import com.reactnativenavigation.NavigationApplication;

import java.util.Arrays;
import java.util.List;

public class MainApplication extends NavigationApplication {

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

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

  @Override
  public ReactNativeHost getReactNativeHost() {
    return mReactNativeHost;
  }

  @Override
  public void onCreate() {
    super.onCreate();
    SoLoader.init(this, /* native exopackage */ false);
  }

    @Override
    public boolean isDebug() {
        // Make sure you are using BuildConfig from your own application
        return BuildConfig.DEBUG;
    }

    @Override
    public List<ReactPackage> createAdditionalReactPackages() {
        return null;
    }

}

And in my react native project:

import Video from 'react-native-video';

  <View style={styles.container}>
        <Video source={{uri: "youtube.com"}}  
          ref={(ref) => {
            this.player = ref
          }}   
resizeMode="cover"  
style={styles.backgroundVideo} 
/>
</View>

Answer 1

createAdditionalReactPackages should return the packages.

Change this

@Override
public List<ReactPackage> createAdditionalReactPackages() {
    return null;
}

to this:

@Override
public List<ReactPackage> createAdditionalReactPackages() {
    return getPackages();
}
