问题
I am trying to run Proguard on my Android app and running into issues.
I am using SpongyCastle jar (copy and past of full bouncy castle with package renamed so it does not conflict with androids bouncy castle built in version)
When running proguard I see the following
How do I fix this? Add rt.jar to my libs?
The whole point of proguard is to shrink the code, but I keep adding jars to get around these issues where proguard complains it cannot find a class! Am I missing something?

I used android update project --path . to generate the build.xml as the project was created sometime ago and I haven't made any changes

I don't think there is a need to add rt.jar to your libs. You need to make sure you are referencing it properly in your proguard script. Take a look here for an example. This line in section 2 is the money maker:
-libraryjars ${java.home}/lib/rt.jar
Although, that syntax changes if you use the xml notation for proguard. If you post the part of the ant script that is responsible I can try to be of more assistance. Hope this helps!

Add the following, -dontwarn javax.naming.** , to your Proguard configuration.
They are just warnings, and ignoring them shouldn't be an issue.
