Android – Webview not loading at first time

androidhttpswebview

I'm struggle with a strange issue. I'm trying to load a https web page, but the first time the webview doesn't load. After wait 60 seconds, I have to click again in my button to load my page. My device is a Nexus 4 with Lollipop, but this issue happens at devices with Android 4.4 and 4.1 as well. The URL doesn't have heavy content only a few javascript files and css files.

Log:

My code:

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());
        }
    });
*/

I set a new WebClient() overriding the following methods: shouldOverrideUrlLoading, onLoadResource, onPageFinished.For tests purpose, I removed this custom WebClient but it still wasn't load at the first time.

Thanks

Best Solution

I met the same issue. I spent more than 3 days and found the cause it that another WebView object calls pauseTimers() for saving some CPU performance which actually " Pauses all layout, parsing, and JavaScript timers for all WebViews."
