보인다 추가하려면 ACCESS_NETWORK_STAT

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example" android:versionCode="1" android:versionName="1.0" >

     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" > 
     <!-- more data goes here... -->
