adbi - The Android Dynamic Binary Instrumentation Toolkit
=========================================================
Simple binary instrumentation toolkit for Android ARM + Thumb.
Instrumentation is based on library injection and hooking function entry
points (in-line hooking).
The toolkit consists of two main components the hijack tool and the base
library.
**hijack**
The hijack tool provides the injection functionality. It supports a number of modes for supporting older and newer Android devices. hijack provides help on the command line.
**libbase**
The base library provides the hooking and unhooking functionality. The base library is compiled as a static library so it can be directly included in the
actual instrumentation library. This is done so we can keep everything in /data/local/tmp.
Below we provide and easy to follow step-by-step instructions for howto build and use adbi. The example instrument hijacks epoll_wait() and logs every call
to a file.

=== Prerequisites ===
Android SDK
Android NDK
=== How to Build ===
= build the hijack tool =
```
cd hijack
cd jni
ndk-build
cd ..
adb push libs/armeabi/hijack /data/local/tmp/
cd ..
```
= build the instrumentation base code =
```
cd instruments
cd base
cd jni
ndk-build
cd ..
cd ..
```
= build instrumentation example =
```
cd example
cd jni
ndk-build
cd ..
adb push libs/armeabi/libexample.so /data/local/tmp/
```
=== How to Run ===
```
adb shell
su
cd /data/local/tmp
>/data/local/tmp/adbi_example.log
# GET PID from com.android.phone
./hijack -d -p PID -l /data/local/tmp/libexample.so
cat adbi_example.log
```
output should look similar to:
```
started
hooking: epoll_wait = 0x4004c378 ARM using 0x4a84a588
epoll_wait() called
epoll_wait() called
epoll_wait() called
removing hook for epoll_wait()
```
