title: How to read a text file character by character in android?
body: <p>I would like to know how can I read a text file from assets character by character.</p>
  
  <p>For example, if I have this file "text.txt" and inside of it "12345", I would like to read all numbers one by one.</p>
  
  <p>I've already looked for this but I can't find any solution.</p>
  
  <p>Thanks.</p>
