This is the home of the .dex manipulation library (slicer) and command line tool (dexter).
Both the command line tool and the library can be built for host and device targets.
To build dexter:
$ m dexter
To test dexter:
# in tools/dexter (and assuming a Linux host) $ python dexter/dexter_tests.py -cmd ../../out/host/linux-x86/bin/dexter -root testdata
