Question

我在谷歌上尝试了几乎所有的帮助，但它仍然没有在我的项目上工作。

我试图将网站设置为Android Web App，并且当浏览器的窗口变小时，网站上会出现<a href="tel:>标记。

当我将其作为Android Web应用程序制作时，即使我采用其他人引导我做的正确方式，电话也无法正常工作。应用程序保持向我显示＆＃34;此页面不可用＆＃34;

寻求你的帮助！

以下是我的代码

Answer 1

你应该返回假

这对你很好：

private class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {

            if (url.startsWith("tel:")) {
                Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse(url));
                startActivity(intent);
                return true;
            }
            return false;
        }
    }

Answer 2

我以这种方式进行设置：

seek(0)

必须在google.com通话之前拨打电话。

拨打电话不适用于Android WebView
