Pass method signature in exit and entry hooks Previously app-inspection relied on java relied on java stacktracing to find which method was called. But that approach was slow and wasn't able to differ between method overloads. Speed. This approach is noticeably quicker than using jmvti's stackstraces and allows us to further cut down overhead per query in db inspection. In my test case numbers are 100ms with this CL and 300ms with native stacktraces Downsides. Currently transformations doesn't take debug information into the account. As a result when exit hooks takes over register or scratch registers are allocated debugger still receives old information that doesn't match execution. This problem existed before this change, this CL makes it slightly worse by using register that was previously used in "start locals". Test: sign_exit_hook + tests in tools/base app-inspection bug: 159250979 bug: 171812449 Change-Id: Idc0ceb01e2ec9f375b2ffef5c57f89209370c223
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
