How can I get Resources by name (string) and not by integer

Question

for example:

public final class R {

    public static final class raw {
        public static final int yuri=0x7f040000;
    }
}

How can I

Answer 1

getResources().getIdentifier( "yuri" , "raw" , getPackageName() );

I found this to be extremely slow. I stripped it out of my whole project after doing some profiling and used int[] instead.
