How to obfuscate an apk with Proguard through Eclipse?

问题

I added proguard.config=proguard.cfgto my default.properties file and have a proguard.cfg file in my project root. If I now use Export as Android Application from within Eclipse I get the following Errors:

[2011-01-27 11:11:37 - Application] Warning: class [classes/com/package.Class.class] unexpectedly contains class [com/package.Class]
[2011-01-27 11:11:37 - Application] Warning: class [classes/com/package.Class2.class] unexpectedly contains class [com/package.Class2]
[2011-01-27 11:11:37 - Application] Note: there were 145 duplicate class definitions.
[2011-01-27 11:11:37 - Application] Warning: there were 146 classes in incorrectly named files.
[2011-01-27 11:11:37 - Application]          You should make sure all file names correspond to their class names.
[2011-01-27 11:11:37 - Application]          The directory hierarchies must correspond to the package hierarchies.

[2011-01-27 11:11:37 - Application]     at proguard.ProGuard.main(ProGuard.java:499)

It seems that somehow my classes are saved in a classes subfolder but Proguard uses this classes subfolder as a package. Therefore the definition of the classes can not be understood by Proguard.

Is this a problem with my SDK Setup? Or are there errors in my Proguard Configuration causing this problem?

回答1:

I changed the proguard.cfg slightly from whatever was working for me last May and now it works:

from

-injars bin

-injars bin/classes

I also had to clean-up a bit--removing Junit (which wasn't used in this project) and the compatibility library (which I probably could have ignored away, but chose to ditch altogether instead).

Now that is convenient I just updated to the the new ddms Eclipse pluging Version: Android DDMS 9.0.0.v201101191456-93220 and updated my SDK to the new Version that includes Honeycomb and the problem seems to be gone.

Steps to get obfusticated apk:

1) Download latest proguard from "http://sourceforge.net/projects/proguard/files/". Current latest version is proguard4.7

2) Replace "bin" and "lib" folder of "C:\Program Files (x86)\Android\android-sdk\tools\proguard" with latest downloaded proguard folders.

3) Check SDK location in eclipse for blank spaces in it and for that go to window > Preferences > Android. If there is blank space then replace it with:

    c:\Progra~2\android\android-sdk (for windows 64-bit)
    c:\Progra~1\android\android-sdk (for windows 32-bit)

4) Check that proguard.cfg file is in your project's root folder and add "proguard.config=proguard.cfg" in project.properties file of android project.

5) Now export your project to get obfusticated apk.

I hope that it will help.
