当我使用备份和还原Webview状态时，我收到此消息：x地址处的网页可能暂时关闭或可能已永久移至新的网址。

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    super.onSaveInstanceState(savedInstanceState);
    webViewShowPoll.saveState(savedInstanceState);                                    
}

@Override
public void onRestoreInstanceState(Bundle outState) {
  super.onRestoreInstanceState(outState);
    webViewShowPoll.restoreState(outState);
}

和Androidmanifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SET_DEBUG_APP"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    


    <activity
        android:name="com.omid.epoll.mobile.Poll"
        android:launchMode="singleInstance"
        android:label="@string/title_activity_poll" 
        android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
    </activity>
