loadUrl() in Android Webview fails with net::ERR_CACHE_MISS -

i working in android studio.i have used webview in main activity. when run project gives error like... "the webpage @ http://www.google.com not loaded because: net::err_cache_miss". please see code: in manifest:

<application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >         <activity             android:name=".defaultactivity"             android:label="@string/app_name"           >             <uses-permission android:name="android.permission.internet"/>             <uses-permission android:name="android.permission.change_network_state"/>             <uses-permission android:name="android.permission.android.permission.access_network_state"/>             <intent-filter>                 <action android:name="android.intent.action.main" />                 <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>     </application> 

in activity:

webview _taskorganizerview = null;     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_default);         _taskorganizerview =   (webview)findviewbyid(r.id.wvtskorg);         _taskorganizerview.getsettings().setjavascriptenabled(true);         if (build.version.sdk_int >= 19) {             _taskorganizerview.getsettings().setcachemode(websettings.load_cache_else_network);         }         _taskorganizerview.loadurl("http://www.google.com");         _taskorganizerview.setwebviewclient(new webviewclient() );     } 

in layout:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"     android:layout_height="match_parent" android:paddingleft="@dimen/activity_horizontal_margin"     android:paddingright="@dimen/activity_horizontal_margin"     android:paddingtop="@dimen/activity_vertical_margin"     android:paddingbottom="@dimen/activity_vertical_margin" tools:context=".defaultactivity">      <webview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:id="@+id/wvtskorg"         android:layout_alignparentbottom="true"         android:layout_alignparentright="true"         android:layout_alignparentend="true"         android:layout_alignparenttop="true"         android:layout_alignparentleft="true"         android:layout_alignparentstart="true" />  </relativelayout> 

your code:

if (build.version.sdk_int >= 19) {             _taskorganizerview.getsettings().setcachemode(websettings.load_cache_else_network);         } 

if never load "http://www.google.com", setcachemode load_cache_else_network error,you can :

webview.setwebviewclient(new webviewclient() {              @override             public void onreceivederror(webview view, int errorcode,                     string description, string failingurl) {                 super.onreceivederror(view, errorcode, description, failingurl);                 //setwebview gone             }              @override             public void onpagestarted(webview view, string url, bitmap favicon) {                 super.onpagestarted(view, url, favicon);              }              @override             public void onpagefinished(webview view, final string url) {                 super.onpagefinished(view, url);               }
