webView的基本使用

WebUtil.syncCookie(viewModel.webUrl.get(), SharedPreferencesUtils.getProperty(this, "cookice"));
        final WebSettings webSettings = binding.webView.getSettings();
        // 设置与Js交互的权限
        webSettings.setJavaScriptEnabled(true);
        binding.webView.setWebChromeClient(new WebChromeClient() {
            @Override
            public boolean onConsoleMessage(ConsoleMessage consoleMessage) {

            @Override
            public void onProgressChanged(WebView view, int newProgress) {
                super.onProgressChanged(view, newProgress);
                if (newProgress == 100) {
                    binding.progressBar.setVisibility(View.INVISIBLE);//加载完网页进度条消失
                } else {
                    binding.progressBar.setVisibility(View.VISIBLE);//开始加载网页时显示进度条
                    binding.progressBar.setProgress(newProgress);//设置进度值
                }
            }

            @Override
            public void onReceivedTitle(WebView view, String title) {
                super.onReceivedTitle(view, title);

        // 绑定webview，支持h5埋点的关键步骤
        // 如需支持h5统计，需要将 assets/mobstat.js 拷贝到工程目录下
