How exactly the R.string.* constants are generated?

Issue

I'd like to store the generated constants of R.string in a DB.

Are the constants generated (semi-) randomly and can change e.g. between versions? Or are they are built like hashCode, so their values remain unchanged as long as XML-file <string/> elements is not touched?

Solution

You shouldn't store R.java constants in a database, as their values can change when the application is recompiled.

Consider creating a Map<Integer, String> of some sort instead, where the keys are integer R.string IDs and the values are String constants. As long as each String constant corresponds to a unique R.string ID and their values never change, you can store them in the database instead.
