android webview设置和遇到的坑

WebSettings webSettings = webView.getSettings();
webSettings.setCacheMode(webSettings.LOAD_NO_CACHE);//设置不缓存
webSettings.setJavaScriptEnabled(true); //支持JS
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
}
 webView.setInitialScale(50);//设置显示的缩放比例

        String URL = "http://192.168.3.23:8082/#/bigScreen?id=123456";
        webView.loadUrl(URL);
//加载页面需要设置谷歌浏览器内核
        webView.setWebChromeClient(new WebChromeClient() {
            @Override
            public void onReceivedTitle(WebView view, String title) {
                super.onReceivedTitle(view, title);
            }
            @Override
            public void onProgressChanged(WebView view, int newProgress) {
                super.onProgressChanged(view, newProgress);
                if (newProgress == 100) {
                }
            }
        });
