Facebook, Twitter and Gmail Integration in Android App

I have to share a link to facebook, twitter and gmail. I have implemented facebook integration using Facebook Sdk in my Android app, thus I am able to share my link to facebook. But if I am following the same procedure for twitter, facing lots of problem to integrate it in my app. Please help to solve this problem. Also I am not getting how to integrate same for gmail. Any ideas are welcome.

Thanks in advance
