ResValue in android Gradle - makes resValue override a string with the same name

Question

In the android build.gradle file, I want to try resValue defined in this style:

 resValue "string", "suffix", "- Pro" 

but in strings.xml I already have a line called "suffix" and it is also localized to other lines.

I want to know if I can define this in my build.gradle file, will it override those contained in any strings.xml file or only by default, etc.? What does resValue or strings.xml ?
