Proguard: how obfuscate just two method?

Question

I try use just it in proguard-rule.txt

-keep class !com.some.package.MyActivity { 
            private void onePrivateMethod(); 
            private void twoPrivateMethod(); 
}

But happens error.

Warning:'com.google.android.gms.ads.AdRequest$Builder setLocation(android.location.Location)' in program class com.google.android.gms.ads.AdRequest$Builder
Warning:there were 1 unresolved references to program class members.
         Your input classes appear to be inconsistent.
         You may need to recompile the code.       
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedprogramclassmember)    
:proguardRelease FAILED
Error:Execution failed for task ':proguardRelease'.
> java.io.IOException: Please correct the above warnings first.

I try rebuild project.

UPD logcat after adding -dontwarn com.google.**

don´t know how, but the first error with the admob You can prevent by enter into proguard : -dontwarn com.google.gms.** — Opiatefuchs, Jan 21 '15 at 07:52
@Opiatefuchs okey, it work. but now was obfuscated all other classes and application crashed — andreich, Jan 21 '15 at 08:00
don´t know if this is the issue, but be sure that You wrote -dontwarn com.google.gms.** not -dontwarn com.google.** . — Opiatefuchs, Jan 21 '15 at 09:02
ok, then it is good. keep this in Your config, that´s ok, Your new error has nothing to do with that. It seems a gson problem. look here: http://stackoverflow.com/questions/8129040/proguard-missing-type-parameter — Opiatefuchs, Jan 21 '15 at 09:44
but why? I set to obfuscation just one class. If I use them config, my class did't obfuscate — andreich, Jan 21 '15 at 10:46

In summary, thank @Opiatefuchs for help.
I moved the necessary methods in a external class and now I use config.
Allows obfuscate class com.my.pakage.SomeClass and app work perfectly.
