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.
该错误仅发生在 Android 模拟器上，并且是由于在 Android 虚拟设备管理器中选中了“使用 GPU 主机”引起的。如果禁用此选项，错误将消失，但模拟器的性能会差很多。
The other thing you can do is add this to the logcat filter to remove these messages:
您可以做的另一件事是将其添加到 logcat 过滤器以删除这些消息：
Log Tag (regex): ^ (?! (eglCodecCommon))
日志标签（正则表达式）： ^ (?! (eglCodecCommon))
I hope it helped you

I also have problem before, I trying to load Chatango on webview, then my problem solved using this code, try this:
我之前也有问题，我尝试在 webview 上加载 Chatango，然后使用此代码解决了我的问题，试试这个：
import android.webkit.WebSettings; //dont forget import WebSettings
then webView attribute:
然后 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);
