title: How to change values in a compiled apk?
body: <p>I want to create an app in which I want to change some values like some colors which are located in <strong>res/values/colors.xml</strong>. I want to create a patch file which will be able to modify my app later.</p>
  
  <p>Basically, I am making an app lock where I want to update the lock screen later with different kind of backgrounds and change the colors of buttons and texts.</p>
  
  <p>For example: See CM AppLock. Where the user is able to download the theme from the play store and install it and the lock screen changes as per the theme.</p>
