Why should I use the R.id, as opposed to the code it generates?

Question

I mean, besides code cleanliness, is it a preference, or a taboo? I'm just curious.

For instance:

public static final class layout {
public static final int main=0x7f030000;

why not use "0x7f030000" instead of "R.id.main"?

Answer 1

The IDs generated in R.id are not static. Any additional IDs you add to any of your XML files may change previously generated values. Therefore you should always use R.id.your_id as those are static.
