How to obfuscate an Android library (.jar file) using Proguard in Eclipse

Question

I have seen many posts about how to obfuscate an Android application (.apk file) using ProGuard in Eclipse. Also see http://developer.android.com/guide/developing/tools/pro

Answer 1

The way to invoke ProGuard is fairly straightforward:

1. Add the line proguard.config=proguard.cfg to project.properties
2. Export the application package

A default proguard.cfg file should have been automatically created by the new project wizard.
