binary_to_integer
)
$ git clone https://github.com/dnet/abx.git
...
$ cd abx
$ erlc *.erl
abx.sh
can be invoked from the shell and can be used to transform XMLs, an
example can be seen below that enables on-device debugging.
$ unzip foo.apk AndroidManifest.xml
Archive: foo.apk
inflating: AndroidManifest.xml
$ ./abx.sh AndroidManifest.xml
Self-test succeeded, proceed with injection
$ ./abx.sh AndroidManifest.xml out.xml application.debuggable=true
The resulting XML can be repackaged into the APK, but then you'll need to sign the package again, here's a blogpost telling you how. If you need more flexibility and know some Erlang, the following modules can be used.
abx_parser
transforms the binary XML to simple Erlang termsparse_file
parses a file specified by nameparse_binary
does the same, but directly on an Erlang binary
abx_serializer
serializes the Erlang terms to binary XML formatserialize_to_file
writes the output to a fileserialize_to_binary
returns the output as an Erlang binary
abx_transform
compiles and applies transformations on Erlang terms
The Erlang term structure is a list, in which each item matches a chunk in the Android Binary XML format. The list items are tuples, the first element is always an atom that tags the contents. Currently, three such tags are supported.
{string_pool, [String1, String2, ...]}
represents a string pool, the second member is a list of binaries; the order matches the original chunk{element, LineNum, Comment, Namespace, Name, [{Ns, Name, Value}, ...]}
represents the start of an XML element with zero or more attributes as tuples of three elements. Namespaces and names are represented as binaries, values are represented as the following.- booleans follow Erlang convention by using
true
andfalse
atoms - decimal numbers are Erlang integers
- hexadecimal numbers are tagged tuples
{hex, Number}
- references are tagged tuples
{ref, Number}
- booleans follow Erlang convention by using
{unknown, Type, HeaderSize, Payload}
represents every other chunk
