title: App Force Closes when trying to do HTTP URL Connect
body: <p>I am new to Android Programming. This is my first app. As part of the app, when i click on a button, I am trying to connect to a URL using the HTTP URL Connect method described on the android documentation. However, my app force closes the moment I click on the button. I have added Internet access and Access Network State permissions in my manifest file as well. 
  Following is my code : </p>
  
  <pre><code>public class GET_PNR extends Activity implements OnClickListener {
  
   private String readStream(InputStream is) {
          try {
            ByteArrayOutputStream bo = new ByteArrayOutputStream();
            int i = is.read();
            while(i != -1) {
              bo.write(i);
              i = is.read();
            }
            return bo.toString();
          } catch (IOException e) {
            return "";
          }
      }
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_get__pnr);
      View txtview = findViewById(R.id.get_pnr);
      txtview.setOnClickListener(this);
  }
  
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      // Inflate the menu; this adds items to the action bar if it is present.
      getMenuInflater().inflate(R.menu.get__pnr, menu);
      return true;
  }
  
  @Override
  public void onClick(View v) {
      // TODO Auto-generated method stub
      TextView pnrview = (TextView) findViewById(R.id.PNR);
      CharSequence input;
      input = pnrview.getText();
      System.out.println(input);
      String result;
  
      HttpURLConnection urlConnection = null; 
      try{
          URL url = new URL("http://www.google.com/");
          urlConnection = (HttpURLConnection) url.openConnection();
          InputStream in = new BufferedInputStream(urlConnection.getInputStream());
          result = readStream(in);
         System.out.println(result);
      } catch (MalformedURLException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
      } catch (IOException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
      }
           finally {
               urlConnection.disconnect();
             }
       }
  }
