 AndroidManifest.xml增加权限方面的配置：

    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" >

    </uses-permission>

    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" >

    </uses-permission>

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" >

    </uses-permission>

    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" >

    </uses-permission>
