title: Pull data from online file into local variable
body: <p>If I have a textfile online containing a string, how can I pull the data from it and save it into a local String variable?</p>
  
  <p>For example, say there is a file located at www.myserver.com/File.txt and it only contains one line: "12345"</p>
  
  <p>How can I have my app read the file, and save the "12345" as a string variable that can be used within the app? </p>
