Communication with the service provider failed: https://api.linkedin.com/uas/oauth/requestToken

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try Launching the Activity.
2. LinkedIn will fail to return request token.
3. WebView will be blank.

I am trying to retrieve user profile from LinkedIn. But while retrieving 
request token from LinkedIn, I'm getting following error:

com.google.code.linkedinapi.client.oauth.LinkedInOAuthServiceException:

The code I'm using was working before. It has stopped few days back 
unexpectedly. Attached is my code. Please reply as soon as possible.

I have also tried placing request twice i.e. in catch block of first request. 
Also tried synchronizing time but that doesn't work either.

The error has now changed to 

Caused by: 
com.google.code.linkedinapi.client.oauth.LinkedInOAuthServiceException: 
oauth.signpost.exception.OAuthCommunicationException: Communication with the 
service provider failed: Host is unresolved: api.linkedin.com:443

I haven't changed my code. Also I've added internet permission in manifest file.

Please tell if I am doing anything wrong.
