dexterity is a C library intended for manipulation and analysis of DEX files. It has python bindings for all basic DEX structures and most of the manipulation functions.
WARNING: This library is still in it's early stages of development, use at your own risk!
The following example parses a DEX file using the built-in parser and then writes a new DEX file from the parsed structures in memory.
#!/usr/bin/python
from dx.dex import Dex
dex = Dex("classes.dex")
dex.save("mirror.dex")The following example parses a DEX file, add a string to it, creates a new DEX file with the modifications and fix the signature and checksum of the new file.
#!/usr/bin/python
from dx.dex import Dex
from dx.hash import update_signature
from dx.hash import update_checksum
dex = Dex("classes.dex")
dex.add_string("Hello World")
dex.save("hello.dex")
update_signature("hello.dex")
update_checksum("hello.dex")For more examples of other usages of the library, check the examples folder.
