weex a组件、navigator跳转问题

Question

weex件了一个页面，通过ios/Android/web进行访问js测试，a组件及按钮navigator跳转在Android无效，使用Utils.goToH5Page在Android也无效

<script>
goToH5Page (jumpUrl, animated = false, callback = null) {
    const Navigator = weex.requireModule('navigator');
    const jumpUrlObj = new Utils.UrlParser(jumpUrl, true);
    const url = Utils.appendProtocol(jumpUrlObj.toString());
    Navigator.push(
      {
        url: Utils.encodeURLParams(url),
        animated: animated.toString()
      },
      callback
    );
  },

</script>

<template>
  <div>
    <wxc-button text="Open Popup"
                @wxcButtonClicked="buttonClicked">
    </wxc-button>
    <wxc-popup width="500"
               pos="left"
               :show="isShow"
               @wxcPopupOverlayClicked="overlayClicked">
    </wxc-popup>
    <a href="http://www.taobao.com">
    <text>Jump2323</text>
  </a>
  </div>
</template>
<script>
  const navigator = weex.requireModule("navigator");
  import { WxcButton, WxcPopup,Utils } from 'weex-ui';
  import downgrade from '@weex-project/downgrade';
  //downgrade.force()
  module.exports = {
    components: { WxcButton, WxcPopup,Utils },
    data: () => ({
      isShow: false
    }),
    methods: {
      buttonClicked () {
        
          this.isShow = true;
          console.log(Utils.encodeURLParams("http://www.baidu.com"));
          
          navigator.push({
          url: "http://www.taobao.com",
          animated: "true"
        });
        this.src = 'http://m.taobao.com'
      },
      overlayClicked () {
        this.isShow = false;
      },getEntryUrl(name) {
      // 判断当前的环境，适配web端
          if (weex.config.env.platform === "Web") {
              return './' + name + '.html'
          } else {
              let arr = weex.config.bundleUrl.split('/');
              arr.pop();
              arr.push(name + '.js');
              return arr.join('/');
          }
      }
    }
  };
</script>

以下思路仅供参考：

可能是以下几个原因导致在Android端使用Utils.goToH5Page时无效：
1、在Android端，需要在应用的Manifest文件中添加对WebView组件的权限声明，例如：
{  
  "permission": {  
    "android.permission.READ_EXTERNAL_STORAGE": {  
      "scope.userVisible": true,  
      "description": "允许用户访问外部存储"  
    }  
  },  
  "application": {  
    "webview.enabled": true  
  }  
}

2、需要将WebView组件添加到MainActivity中，例如：
public class MainActivity extends AppCompatActivity {  
    private WebView webView;  
  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
  
        webView = findViewById(R.id.web_view);  
        webView.getSettings().setJavaScriptEnabled(true);  
        webView.getSettings().setDomStorageEnabled(true);  
        webView.getSettings().setDatabaseEnabled(true);  
        webView.getSettings().setAllowFileAccess(true);  
        webView.getSettings().setAppCacheEnabled(true);  
        webView.getSettings().setAllowUniversalAccessFromFileURLs(true);  
        webView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);  
        webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);  
        webView.getSettings().setUseWideViewPort(true);  
    }  
  
    public void gotoH5Page() {  
        if (null == webView) return;  
  
        webView.loadUrl("https://example.com");  
        webView.setWebViewClient(new WebViewClient() {  
            @Override  
            public void onPageFinished(WebView view, String url) {  
                super.在Android端，需要在应用的AndroidManifest.xml文件中添加对WebView组件的权限声明，例如：  
  
  
```xml  
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />  
  
<application  
    android:allowBackup="true"  
    android:icon="@mipmap/ic_launcher"  
    android:label="@string/app_name"  
    android:theme="@style/AppTheme" >  
    <activity  
        android:name=".MainActivity"  
        android:label="@string/app_name" >  
        <intent-filter>  
            <action android:name="android.intent.action.MAIN" />  
            <category android:name="android.intent.category.LAUNCHER" />  
        </intent-filter>  
    </activity>  
</application>
3、可能需要调整一下AndroidManifest.xml中WebView组件的权限，例如：
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />  
  
<application  
    android:allowBackup="true"  
    android:icon="@mipmap/ic_launcher"  
    android:label="@string/app_name"  
    android:theme="@style/AppTheme" >  
    <activity  
        android:name=".MainActivity"  
        android:label="@string/app_name"  
        android:hardwareAccelerated="true"  
        android:configChanges="orientation|screenSize
