android – Webview没有第一次加载

我为一个奇怪的问题奋斗.我正在尝试加载一个https网页,但是第一次加载webview.等待60秒后,我必须再次点击我的按钮才能加载我的页面.我的设备是带有Lollipop的Nexus 4,但是此问题发生在 Android 4.4和4.1的设备上.该网址的内容不多,只有几个javascript文件和css文件.

我的代码：

final WebView wv = (WebView) alert.findViewById(R.id.modal_wv);

    wv.getSetTings().setAppCacheEnabled(true);
    wv.getSetTings().setCacheMode(WebSetTings.LOAD_DEFAULT);
    wv.getSetTings().setAppCachePath("/data/data/" + getPackagename() + "/cache");
    wv.getSetTings().setAllowFileAccess(true);
    wv.getSetTings().setJavaScriptEnabled(true);
    wv.loadUrl(connectionResponse.getUrl());
/*
//Same behavior ...
    wv.post(new Runnable() {
        @Override
        public void run() {
            wv.loadUrl(connectionResponse.getUrl());
        }
    });
*/

我设置了一个新的WebClient()覆盖以下方法：shouldOverrideUrlLoading,onLoadresource,onPageFinished.For测试目的,我删除了这个自定义的WebClient,但它仍然没有第一次加载.

谢谢
