我正在尝试为Android浏览器制作一个Web浏览器，我正在使用android studio。我的充气代码。
@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();
}
});
完整错误如下：

我已经在我的xml中输入了正确的id作为wvBrowser，我在android Manifest xml文件中拥有用户权限。有人知道这个问题吗？提前致谢。
答案 0 :(得分：3)
您无法在可穿戴设备上使用WebView，请在此处查看不可用功能列表： 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，它无法访问互联网，只能从配套手持设备接收数据。
编辑： 实际上，我只看到一种方法：
