I use the above Code for making connection for twitter but it only works for one time if I want another time for connection then it never provide me second time connection.

Thankx

Could this be an Activity lifecycle issue? Your call to getTwitter() occurs in onCreate, which only gets called when the Activity is created. If a user navigates away then comes back to your app, it may still be running, so onCreate would not get called again. Have a look at the Activity lifecycle, and add some debug code to each of the lifecycle methods (onResume, onPause etc) to get an idea of when they are called.
