How to suppress 'Maybe this is program method' warnings from ProGuard

I'm using ProGuard with my Android application and I'm running getting the warnings below in my build log. I've added the appropriate '-keep public class com.foo.OtherClass { public static *; }' statement to my proguard.cfg file, but I still get the 开发者_如何学Pythonwarnings. My app runs fine and is dynamically accessing the class correctly. Is it possible to suppress these warnings?

[proguard] Note: com.foo.MyClass accesses a method 'getInstance()' dynamically
[proguard]       Maybe this is program method 'com.foo.OtherClass { com.foo.OtherClass getInstance(); }'

You can avoid it by explicitly mentioning the method in the configuration:

-keep class com.foo.OtherClass { com.foo.OtherClass getInstance(); }

Alternatively, you can suppress notes on a class:

-dontnote com.foo.MyClass

You suppress all messages of type Note by adding the following line:

-dontnote **
