body: <p>I want selectable text to be bold. I did it using Spans. </p>
  
  <p>But there is a problem that I can not write this text with spans to .txt</p>
  
  <pre><code> SpannableString string = new SpannableString(selectedText);
   string.setSpan(new StyleSpan(Typeface.BOLD), 0, selectedText.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
   mEditText.setText(mEditText.getText().replace(startSelection, endSelection, string, 0, string.length()));
  </code></pre>
