derg

DERG (.dex element relation graph) is a graph representation of code. It is general representation which can be used in Android app reverse-engineering, for example:

• Getting the class hierarchy (inherit, implements, etc.) of an Android app;
• Extracting the APIs used in each method;
• Extracting the call-return relation (a simplified call-graph);
• Extracting the define-use relation between methods and fields.

Prerequisite

• Java 7
• Maven

Installation

1. Clone this repo.

git clone https://github.com/ylimit/derg.git

2. Compile with Maven

cd derg
mvn package

Then find the compiled jar file in target directory.

Usage

Please type java -jar DERG.jar -h to see detailed usage information. Typical usage:

java -jar DERG-1.0.jar -i <your_app.apk> -o <output_dir> -f soot -b graph_export -sdk ~/Android/Sdk/platforms/android-22/android.jar

This command will generate the DERG representation of an app.
