android - WebView is not able to show Website -

here code:

xml

   <webview     android:id="@+id/webview"     android:layout_width="match_parent"     android:layout_height="match_parent"     /> 

mainactivity.java excerpt

    @override     protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      webview mywebview = (webview)findviewbyid(r.id.webview);     mywebview.loadurl("http://www.google.com");     mywebview.setwebviewclient(new webviewclient()); } 

this should show google page upon starting app. every time run this, error of "webpage not available, webpage might temporarily down or may have moved new web address, etc"

any ideas?

make sure connected internet , have following permission in manifest:

<uses-permission android:name="android.permission.internet"></uses-permission>
