Appfence is an android sandbox that provides both traditional file/network isolation as well as Android-specific sandboxing. Appfence provides two major functionalities:

• redirect files accessed by the sandboxed app. Thus the sandboxed app cannot access files belonging to the same app in normal mode.
• Android API sandboxing, which is under investigation.

Note: Appfence operates on system call level (ptrace-based).

The project is mainly using Android NDK toolchain (compilers, scripts, debuggers) for development. Also Android SDK is needed if the actual device is needed for development.

• We need some environment variables in Eclipse for the NDK path. Here are the pics.
• First setup the Android NDK path:
• Second setup the environment variables. Note that on Windows the build script is ndkbuild.cmd. On Linux it is ndkbuild.
• Now import the project to Eclipse, you should see include/ resolved.

• There is no auto build enabled. So once the code is changed, you need to go to Run->Build All.
• Make sure NDK build works fine and no errors pop up (in best case, no warnings too).

• The testng can be done in an emulated device or an actual device. An external tool is provided to upload the executable and launch it. The launch configuration is appfence cpp.launch, which in turns calls the run.bat script.

• The GDB way will come soon

• The Android.mk in the jni folder is the build script, which is straightforward. Everytime you add new source files, add it to this makefile.
• The Makefile at the project root folder is just for non-Eclipse developers.
• Note that you cannot change the jni folder name, which is identified by the Android build tool chain.
