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

I have found solution:

1. Get Proguard - copy proguard.jar into known directory (say MyProject/proguard)
2. Prepare proguard.cfg -describing what and how optimize/obfuscate. This process thoroughly described in Proguard's manual
3. Prepare following ANT's build.xml (or smth like this one) - great thanx to this guy

UPDATE complete build.xml

1. This ANT task has to be added to Eclipse's builders (Properties/Builders) tasks after Java builder and before Android package builder.

2. Press "Build All" (it's better to off Automatic Build check in Eclipse menu)
