[android-developers] VPN connection status on ICS

[Stigi]

Hello,
I'm trying to register receiver, that will check VPN status. I have tried 
this: 
http://stackoverflow.com/questions/3461967/get-vpn-connection-status-on-androidbut
 looks like it no longer works on ICS. I have checked android source 
code for some clue, but with no luck, only noticed that in ISC there is 
nothing like: "vpn.connectivity" and "connection_state" - it use to be in 
android 2.3. Also tried using "android.net.conn.CONNECTIVITY_CHANGE" as my 
IntentFilter, but it doesn't react on VPN connection at all (of course I 
have added permission "android.permission.ACCESS_NETWORK_STATE"). 
I thought that it is simple thing to do, but I already run out of ideas how 
to do it... Could someone help me with this please?
Thanks in advance,
Stigi

Re: [android-developers] VpnService basic questions

[Stigi]

Are you sure that it is whatever you code yourself? Because right here: 
http://developer.android.com/sdk/android-4.0-highlights.html if I under it 
stand right, it is said that VpnService supports only L2TP and IPSec 
protocols. On the other hand, if I am wrong, could you give us a hint how 
to code PPTP connection?

Thanks in advance
