How to check Internet is Available or Not in Android?

Hi,

   I tried to send the data only when internet connection available. I Connected to Local Network. But that's protected by firewall. So, I can't access Local Network Without Permission. 

  I used Application.internetReachablity to check internet connection. 

  If i connected to that Local Network. But, don't have permission. Clicking send will Check for internet Connection. (Application.internetReachability returns true). I can't able to connect the internet. 
 
 How could i Check that Internet connection Availability on this scenario.?

Even i saw these post didn't get the solution.

Help to solve this issue?

But in Windows Phone 8 : I use the following code to solve that issue,

 if (DeviceNetworkInformation.IsNetworkAvailable && (DeviceNetworkInformation.IsWiFiEnabled || DeviceNetworkInformation.IsCellularDataEnabled))
 {
 //internet Available
 }
 else
 {
 //internet Not Available
 }
