title: Does proguard remove unused classes in android.jar?
body: <p>Suppose i am developing an application using android api 16, my app will include android.jar. I would be importing few classes from the jar file.</p>
  
  <p>I would enable proguard in release mode by configuring proguard. Does proguard remove unused classes in android.jar also?</p>
  
  <p>Edit:</p>
  
  <p>properties file for my project</p>
  
  <p>android.library.reference.1=../actionbarsherlock</p>
  
  <p>So does proguard remove unused classes from my library project included when packaging everything to .apk ?</p>
