title: Android application crash after using action_view intent
body: <p>I have a strange error , Here's my code </p>
  
  <pre><code>String a;
  String b;
  a="http://website1.com/abcabc1";
  String[] separated = a.split("/");
  b = separated[3];
  
  String url = "www.website2.com/" + b;
  Intent i = new Intent(Intent.ACTION_VIEW);
  i.setData(Uri.parse(url));
  startActivity(i);
  finish();
  </code></pre>
  
  <p>What I want to do is getting the the value after .com/" in string a "which is abcabc1" and then open a new url which will be "www.website2.com/abcabc1" but the problem I have is the application crashes upon launch . I tried to discover the source of the problem and what i found was that if my code was : </p>
  
  <pre><code>String url = "www.website2.com/";
  </code></pre>
  
  <p>It will work without any problem , but if it was like this : </p>
  
  <pre><code>String url = "www.website2.com/" + b;
  </code></pre>
  
  <p>Application will crash . </p>
  
  <p>Note If I try to set string url as textview text it shows it in the correct form but if i pass it to browser it crashes . Sorry for my poor language and thanks in advance . </p>
  
  <p>Update :
  Catlog : </p>
