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

问题

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 warnings. 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(); }'

回答1:

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

回答2:

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

-dontnote **
