请在此处发布logcat。 - Arshid KV

抱歉，我不知道如何在代码中插入logcat。 - Amir.KH

Answer 1

这个错误只会在Android模拟器中出现，原因是在Android虚拟设备管理器中勾选了“使用GPU主机”。如果您禁用此选项，则错误将消失，但模拟器的性能将大大降低。

另一件事情是添加以下内容到logcat过滤器中以删除这些消息：

日志标签（正则表达式）：^(?!(eglCodecCommon))

希望对您有所帮助。

只需从正则表达式中删除空格，它就可以工作：^(?!(eglCodecCommon)) - George

Answer 2

我之前也遇到过类似的问题，我尝试在webview中加载Chatango，后来我使用了这段代码解决了我的问题，你可以试试：

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

然后是webView属性：

    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);
