title: String replace android?
body: <p>Im trying to replace a character : on a system date generated so I can put it as a title. It gives me the format:  "ago 29, 2013 7:42:19 p.m.", so I need to change the ":" for " ", with an string replace.  But I dont know how to do it. Ill appreciate your help. Heres my code:</p>
  
  <pre><code>    public void createPDF()
      {
          Document doc = new Document();
  
  
           try {
               Date date = new Date();
              String dateTime = DateFormat.getDateTimeInstance().format(date);
               File sdCard = Environment.getExternalStorageDirectory();
               File dir = new File (sdCard.getAbsolutePath() + "/Bitacora");
               dir.mkdirs();
               File file = new File(dir, "Bitácora "+idetotrocliente.getText().toString()+", "+dateTime+etsitio.getText().toString()+".pdf");
               FileOutputStream fOut = new FileOutputStream(file);
                   }
               catch(Exception)
               {
  
               }
      }
