react-native-video 是否与 react-native-navigation 一起工作

Question

我正在尝试让视频在我的 React 本机应用程序中播放。 I'm trying to use react-native-video 但是当运行通过 react-native run-android 应用程序时，我收到错误消息：

"undefined 不是对象(求值'_reactNative.NativeModules.UIManager.RCT Video.Constants')

这条消息并没有告诉我太多信息，但在尝试让它工作一段时间后，我开始怀疑 react-native-navigation，我在我的应用程序中使用的导航，有一些东西用它来做。因此，我创建了一个新的 react-native 项目并向其中添加了 react-native-video 并使其正常运行。

所以我的问题是，是否有人遇到过同样的事情，并且可以提供让这两个包协同工作的解决方案？

我的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 模块 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'
}

build.grade 模块中的依赖项：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;
    }

}

在我的 React Native 项目中：

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 应该 return 包。

改变这个

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

对此：

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