Steps for Twitter Integration
------------------------------
1. You have to create an Account on Twitter before you do anything.
2. Register you application with Twitter here (https://dev.twitter.com/user)
3. Create new application in twitter
Name:your project name
Description:
website:"enter website"
Callack url="enter url"
then, goes to twitter settings in that application type select Access permission and check the Sign in with twitter button copy the consumer key and secret key
4. open eclipse and create new project
5. write below permissions in manifest file
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
then Download below Library files and add to your project
signpost-commonshttp4-1.2.1.1.jar
signpost-core-1.2.1.1.jar
http://code.google.com/p/oauth-signpost/
httpclient-4.0.1.jar
