我正在尝试为Android Wear制作一个网页浏览器，我正在使用Android Studio进行开发。我的代码用于解析。
    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);
    final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
    stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
        @Override
        public void onLayoutInflated(WatchViewStub stub) {
           webview = (WebView)findViewById(R.id.wvBrowser);
            //this will set javascript enabled.
            webview.getSettings().setJavaScriptEnabled(true);
            //loading url to google.com
            webview.loadUrl("https://www.google.com");

            webview.getSettings().setLoadWithOverviewMode(true);
            webview.getSettings().setUseWideViewPort(true);

            webview.setWebViewClient(new WebViewClient() {
                public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
                    Toast.makeText(getApplicationContext(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
                }
            });

完整的错误信息如下：

我已经在我的xml文件中放置了正确的id，即wvBrowser，并且在我的Android Manifest xml文件中具有用户权限。有人知道问题出在哪里吗？

根据你所说，你的ID是wvBrowser，但在代码中你添加了其他内容。请检查一下。 - user4050065

您不能在可穿戴设备上使用 WebView，请查看以下不可用功能列表： https://developer.android.com/training/wearables/apps/index.html 此外，您无法直接从可穿戴设备连接到互联网，它没有Internet访问权限，只能从配对的手持设备接收数据。
编辑: 实际上，我只看到一种方法：
  1. 在手持设备上加载 HTML 页面并使用 Wearable.DataApi 将其传输到可穿戴设备上
  2. 使用（可以自定义）第三方 HTML 库在可穿戴设备上显示页面。也许 此答案 中的项目在这里会有用。
有没有办法像www.google.com一样显示页面，因为我知道在Google Play上有加载页面并适用于Android Wear的应用程序。 - ilikeyoyo
如果我使用Android Wear 2.0，我能否直接使用Webview而无需连接手持设备？ - kavie
从 Android Wear 2.0 开始，我们可以直接连接到互联网，对吗？ - kavie

目前，至少有一种方法可以确定设备上是否可用WebView。该链接解释了这一点，并且还说WebView在Wear OS上不可用： https://developer.android.com/guide/webapps/managing-webview - Steve White
