And

Java code

1WebView Mywebview =(WebView) Findviewbyid (R.id.webview); 2Mywebview.setwebchromeclient (Newwebchromeclient () {3      Public Booleanonconsolemessage (consolemessage cm) {4LOG.D ("MyApplication", cm.message () + "-From line"5+ cm.linenumber () + "of"6+Cm.sourceid ()); 7         return true; 8     }   9});

*consolemessage also includes a messagelevel that represents the console delivery information type. You can use Messagelevel () to query the information level to determine the severity of the information, and then use the appropriate log method or take other appropriate actions.
