Vkontakte authorization in java?

Question

Java

Hello everyone,
I am developing an application in java and I would like to fasten authorization through VKontakte.
Is there anyone among the readers who has already implemented something similar and can share the code?
Thanks

Check out this VKontakte Android SDK article . There are links to source codes with authorization.

If you need authorization without a WebView, then it looks something like this:

1. //Get the required cookies
2. HttpGet get  =  new  HttpGet ( http : //vk.com/login.php?email=%s&pass=%s);
3. HttpResponse response  =  mHttpClient. execute ( get ) ;
4. if  ( response. getStatusLine ( ) . getStatusCode ( )  ! =  200 )  {
5. throw  new  UpdateException ( "Failed to obtain token" ) ;
6. }
7.  
8. // Make a request for authorization
9. get  =  new  HttpGet ( " api.vk.com/oauth/authorize?client_id=_&redirect_uri=http%3A%2F%2Fapi.vk.com%2Fblank.html&response_type=code&scope=audio ,offline" ) ;
10. response  =  mHttpClient. execute ( get ) ;
11. if  ( response. getStatusLine ( ) . getStatusCode ( )  ! =  200 )  {
12. throw  new  UpdateException ( "Failed to obtain token" ) ;
13. }
14.  
15. //Get the last link we were redirected to
16. final String lastLink  =  redirectHandler. getLastLocationURI ( ) . toString ( ) ;
17. if  ( lastLink. contains ( "oauth.vk.com/oauth/authorize" ) )  {
18. throw  new  VkApiException ( "Failed to login!" ) ;
19. }  else  if  ( lastLink. contains ( oauth. vk . com / authorize ) )  {
20. //Get here if the app doesn't have verified permissions
21. final String approveLink  =  getApproveLink ( EntityUtils
22. . toString ( response. getEntity ( ) ) ) ;
23. get  =  new  HttpGet ( approveLink ) ;
24. response  =  mHttpClient. execute ( get ) ;
25. if  ( response. getStatusLine ( ) . getStatusCode ( )  ! =  200 )  {
26. throw  new  UpdateException ( "Failed to obtain token" ) ;
27. }
28. }
29.  
30. //If everything is fine, then we get the code from the last url
31. final String code  =  extractCode ( redirectHandler. getLastLocationURI ( ) . toString ( ) ) ;
32.  
33. //Get the token using the scribe library
34. final Verifier verifier  =  new  Verifier ( code ) ;
35. final Token token  =   mAuthSevice. getAccessToken ( EMPTY_TOKEN, verifier ) ;

PS It used to work, but it seems that something has changed with them.
