Android R file update at runtime

Is it possible to examine the R file and update its contents via reflection in an Android application. I was looking to change the value various constants defined in the R file ? Is it possible ? Would it make sense ?

It is not possible and, in my opinion, it wouldn't make sense.

The values in the R class change when you build your application and you can never guarantee that they will be the same. The integer values are not meant to be used directly, only they static constants should be used in your code.

R is a set of static fields. There is nothing you can do to change that. Everything is baked into it on compile time.
