title: Implementing PPTP/L2TP Protocols on Android +14
body: <p>I am working on an Android app using <strong>Android Studio v 1.4</strong> and the <strong>minimum sdk version is 14</strong> and what I am trying to do is building a simple VPN client that implements PPTP and L2TP protocols.</p>
  
  <p>I have googled and searched here in Stack Overflow and I have looked at the Android sdk VPN sample called toyvpn and also looked at the official documentation for the VPN Service class.</p>
  
  <p>How to implement PPTP or L2TP with VpnService on Android Platform?
  Is there any code samples,libraries or even a starting point to such an implementation.</p>
