android - Specify class names for Proguard to avoid obfuscating to -

i see proguard can specify dictionary of names used when obfuscating (and these can @ field/method, class or package level).

is there way give list of names not obfuscate to? tried putting ! in front in dictionary didn't seem work. bit of context, i'm thinking not obfuscate class names r avoid conflicts android generated r class.

as aside, it's worth checking out example dictionaries in proguard distribution (examples/dictionaries/) - last 2 made me chuckle!

i stumbled upon question while searching same thing.

this not answer core question,
use-case adding proguard-project.txt should enough:

-keep public class **.r {   public *; }  -keep public class **.r$* {   public *; }
