WebView无法在Android 4.4+中加载url

Question

I have one issue with WebView , one link that simply loads in WebView but it's not working.

The same URL is working fine with versions 4.1, 4.2,4.2.2, and 4.3 of Android OS, but it's not working in versions 4.4 and above.

Url is http://rise.esprit-apps.com/faqs/mobilefaq

That means it's not working in Kitkat, Lollipop, or Marshmallow.

I think it's a cookies problem, but I have enabled cookies in WebView but can't resolve this.

The same URL is working in Chrome and another browser perfectly but it's not loading in default WebView .

If anyone has a solution, please let me know.

Here is my code:

        super.onBackPressed();

    }
}

I got below Error in logcat:

Please Check Migrating to WebView in Android 4.4

Android 4.4 (API level 19) introduces a new version of WebView that is based on Chromium. This change upgrades WebView performance and standards support for HTML5, CSS3, and JavaScript to match the latest web browsers. Any apps using WebView will inherit these upgrades when running on Android 4.4 and higher.

Reference Link: http://developer.android.com/guide/webapps/migrating.html

Hope it will help you.

Answer 2

Try this code:

CookieManager cm = CookieManager.getInstance();
cm.setAcceptCookie(true);

It should be executed before WebView is created.
