在Android的LinkedIn集成中，与服务提供商的通信失败

I am trying to integrate LinkedIn Login in my Android app. I successfully integrated it and it was working fine. But the strange thing is when I run my app today again, i am getting Communication with the service provider failed error. I checked both my Consumer and Secret key. But there was no problem. Also I didn't change my code. One more thing, after getting this error I created a different project with only LinkedIn login. But that is working fine.
