title: Any way to add lines to build.prop upon clicking button?
body: <p>Is there any function/method that I can use that'll add lines to the devices build.prop?</p>
  
  <p>For example there is a build.prop line - <code>pm.sleep_mode=1</code></p>
  
  <p>And I want that line to be added to my device's build.prop when I click a button.
  How can I achieve this? Have searched but it only come sup with scripts?:S</p>
