ANT build for Android Proguard obfuscation

Question

Can anyone share with sample/simple obfuscation ANT task for Android? Provided that I do have complete APK and I need just pass *class hru Proguard and then prepare *.dex to

Answer 1

The proGuard obfuscation process needs .class files so you can't launch an Ant before IDE build (.java) or after (.dex packed).

Have a look on this post where it's explained how add the proGuard step in your global Ant build:

If you really want to use the IDEA build, you can try the following.

• After the IDEA build unpack the apk with apktool.
• Convert the .dex files to .class with dex2jar
• Run proGuard as the previous post show you

Sorry that I don't attach you the links of apktool and dexjar but as I'm newbie I can't post more than one hyperlink.
