Webview未在Chrome Android中打开不同域的链接

Question

我正在尝试为我公司的Web应用程序制作一个应用程序，并且效果很好。唯一的问题是，我有一些来自不同域的链接，例如YouTube，打开了一些视频。与指定为我的域的域相关的所有其他链接将在Webview中打开，并在我的应用程序中显示该网站。但是，Youtube链接和其他外部网站链接无效。

如果我还记得的话，它应该根据链接询问用户是否要使用Chrome或Youtube或Facebook应用程序打开它，但是它不起作用。

这是我的WebView代码：

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final WebView myWebView = (WebView) findViewById(R.id.webview);
        myWebView.loadUrl("http://www.example.com/");

        WebSettings webSettings = myWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        myWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        myWebView.getSettings().setSupportMultipleWindows(true);
        myWebView.setHorizontalScrollBarEnabled(true);
        myWebView.getSettings().setDomStorageEnabled(true); // This will allow access

        myWebView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                if (Uri.parse(url).getHost().startsWith("google.com")) {
                    view.loadUrl(url);
                } else {

                    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
                    startActivity(intent);

                }
                return true;
            }
        });
        myWebView.setDownloadListener(new DownloadListener() {

            public void onDownloadStart(String url, String userAgent,
                                        String contentDisposition, String mimetype,
                                        long contentLength) {
                DownloadManager.Request request = new DownloadManager.Request(
                        Uri.parse(url));
                final String filename = URLUtil.guessFileName(url, contentDisposition, mimetype);
                request.allowScanningByMediaScanner();
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); //Notify client once download is completed!
                request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, filename);
                DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
                dm.enqueue(request);
                Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT); //This is important!
                intent.addCategory(Intent.CATEGORY_OPENABLE); //CATEGORY.OPENABLE
                intent.setType("*/*");//any application,any extension
                Toast.makeText(getApplicationContext(), "Downloading File", //To notify the Client that the file is being downloaded
                        Toast.LENGTH_LONG).show();

            }
        });
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        // Check if the key event was the Back button and if there's history
        WebView myWebView = (WebView) findViewById(R.id.webview);
        if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) {
            myWebView.goBack();
            return true;
        }
        // If it wasn't the Back key or there's no web page history, bubble up to the default
        // system behavior (probably exit the activity)
        return super.onKeyDown(keyCode, event);
    }
}

我已经尝试了所有方法，但无法在网络浏览器中打开来自不同域的链接。怎么了？

也许您可以在 shouldOverrideUrlLoading 方法中尝试此操作，以检查其公司域是否应该通过这种方式在 webView 中打开。它对我有用。

 public boolean shouldOverrideUrlLoading(WebView webView, String url) {
    if(url.indexOf("yourcompanydomain.com") > -1 ) return false;

    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
    activity.startActivity(intent);
    return true;
}

或尝试

if(myWebView.getUrl().startsWith("yourcompanydomain.com")){
                return false ;
}
else
{
Intent....
}
