AndroidManifest.xml 里VPNService权限的声明

<service android:name=".MyVPNService"android:permission="android.permission.BIND_VPN_SERVICE">      <intent-filter>          <action android:name="android.net.VpnService"/>      </intent-filter></service>

android:permission=”android.permission.BIND_VPN_SERVICE” 这个权限声明一定要写在Service的声明里。我之前只写在了全局

<uses-permission android:name="ANDROID.PERMISSION.BIND_VPN_SERVICE" />
