How to change values in a compiled apk?

I want to create an app in which I want to change some values like some colors which are located in res/values/colors.xml. I want to create a patch file which will be able to modify my app later.

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.

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.

The way CM AppLock does it is called "Android Runtime Resource Overlay", aka RRO. Here is a brief Introduction of RRO. The mainstream Android releases have RRO enabled for preinstalled packages(not allowed for downloadable apks). Last I checked the patches for RRO for downloadable apks are still in review. Android O will most likely have this feature. Here is a brief overview of this new feature coming in Android O.
