Answer 1

The error occurs only with the Android emulator, and is caused by having checked the "Use GPU Host" in the Android Virtual Device Manager. If you disable this option, the error will disappear, but the emulator will have a much worse performance.

The other thing you can do is add this to the logcat filter to remove these messages:

Log Tag (regex): ^ (?! (eglCodecCommon))

I hope it helped you

Answer 2

I also have problem before, I trying to load Chatango on webview, then my problem solved using this code, try this:

    import android.webkit.WebSettings; //dont forget import WebSettings

then webView attribute:

    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
    WebSettings websettings = webView.getSettings();
    websettings.setJavaScriptEnabled(true);
    websettings.setDomStorageEnabled(true);
    websettings.setUserAgentString("Mozilla/5.0 (Linux; Android 4.1.2; C1905 Build/15.1.C.2.8) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.114 Mobile Safari/537.36");
    webView.loadUrl(yourUrltoLoad);
