ckitching suggested using javap to produce and upload reports of the contents of the Fennec namespace pre- and post-Proguard. It's a nice idea; here's how to do it. 1) First, add code to mobile/android/base/Makefile.in around  that uses code like  to create two files containing the javap outputs. A Make function (like aapt_command) that took a list of .jar files would be best, 'cuz we have two lists of .jar files that we want to process (see ALL_JARS and the contents of jars-proguarded). Call these files pre-Proguard.javap.txt and post-Proguard.javap.txt. 2) Add these files to the libs:: line, and $(INSTALL) them into $(FINAL_TARGET) as well. 3) Add the files to the UPLOAD_EXTRA_FILES in packager.mk around . 4) Push a try build, and verify your files got built and uploaded to the build directory.  http://mxr.mozilla.org/mozilla-central/source/mobile/android/base/Makefile.in#392  http://stackoverflow.com/a/1171675  http://mxr.mozilla.org/mozilla-central/source/toolkit/mozapps/installer/packager.mk#341
This is a reasonable mentored bug, if you're interested in the Mozilla build system; but not a good first bug.
I am interested to work on it.I am a newbie, can you help please?

Thanks for your interest, but unfortunately this is not a good first (or even second) bug. We always recommend looking at http://www.joshmatthews.net/bugsahoy/?mobile=1&simple=1 for good first bugs that are mentored.
