title: Twitter Login Authentication in Android?
body: <p>I have to do Login Authentication to post the tweets. I got the <code>Jtwitter.jar</code> and <code>SignPost.jar</code> file from <a href="http://www.winterwell.com/software/jtwitter.php" rel="nofollow noreferrer">this link</a>. As far as i searched, the xAuth Authendication is more efficient. But i did not get any simple tutorial or piece of code for Login Authendication yet. I found <a href="http://www.mobisoftinfotech.com/blog/android/1089/" rel="nofollow noreferrer">this Article</a> and used this code. thats get <code>NullPointerException</code>.</p>
  <p>I created the customer key and Secret key also used the code where  got the jar site. That gets <code>Verification Error</code>.</p>
  <p>Please Share some idea or steps to follow to verify the username and password of the user?</p>
  <p>Edit:</p>
  <p>I want to post to from the <code>user's account</code>. what do you prefer to use the Api whether <code>Jtwitter</code> or <code>Oauth</code>? and Tell me <code>How-to</code> or <code>Related Articles</code> ?</p>
