React-native-video [android] Undefined Is Not An Object (evaluating Nativemoduels.uimanager.rctvideo.constants')

I integrated react native to an existing android app, I am trying to use react-native-video component for displaying video on the application. React-native: 0.42.0 react-native-vi

Solution 1:

Fixed adding the ReactVideoPackage when creating the ReactInstanceManager

mReactInstanceManager = ReactInstanceManager.builder()
            .setApplication(getApplication())
            .setBundleAssetName("index.android.bundle")
            .setJSMainModuleName("index.android")
            .addPackage(newMainReactPackage())
            .addPackage(newReactVideoPackage())//<-- this line fixed
            .setUseDeveloperSupport(BuildConfig.DEBUG)
            .setInitialLifecycleState(LifecycleState.RESUMED)
            .build();

Solution 2:

cd ios and pod install and again link library

import React, {Component} from'react';
import {
  View,
  Button,
  Text,
  Platform,
  StyleSheet,
  TouchableOpacity,
  TouchableHighlight,
  Animated,
  ScrollView,
  Image,
} from'react-native';
import Video from'react-native-video';

export defaultclassAppextendsComponent {

  render() {
    return (
      <View style={{flex: 1, marginTop: 50}}>

        <Video
          source={{uri: 'YOUR_URL'}} // Can be a URL or a local file.ref={ref => {
            this.player = ref;
          }} // Store reference
          onBuffer={this.onBuffer} // Callback when remote video is buffering
          onError={this.videoError} // Callback when video cannot be loaded
          style={styles.backgroundVideo}
        />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  field: {
    flex: 1,
    flexDirection: 'row',
    justifyContent: 'space-between',
    paddingTop: 10,
    paddingBottom:10,
  },
  backgroundVideo: {
    position: 'absolute',
    top: 0,
    left: 0,
    bottom: 0,
    right: 0,
  },
});
