title: Android String variable (HH:mm) to long variable miliseconds
body: <p>I have a String variable in this format <code>"HH:mm"</code>.
  Lets say the variable value is 05:30.</p>
  
  <p>How would I be able to get those numbers from string and calculate :</p>
  
  <p>(05 * 60 * 60 * 1000) + (30 * 60 * 1000) and put that number (miliseconds) in a new long variable. </p>
  
  <p>Basically I need to convert the String time variable into miliseconds long variable.</p>
