Nmap wrapper for Android

In 2016 I applied for a GSoC at Nmap with a bid for an Android port of Nmap. I built an ugly prototype with a cross-compiled Nmap shared library, a C wrapper and a simple Android activity to interact with it. The bid was not successful, and probably for good reasons.

In 2022, I thought it would still be nice to be able to run Nmap from time to time from my smartphone. I took the original prototype, polished it a bit and packaged it. It's still ugly, but it does its job. And maybe angry user feedbacks will motivate me to spend some time on it.

Be aware that the script to compile Nmap is based on my development environment. You might need to fix some paths for it to be working on your system.

cd app/src/main/cpp
./make_nmap.sh

The script will do the following:

1. Download latest stable Nmap source (7.94 at the time of writing).
2. Configure and compile Nmap for armeabi-v7a and arm64-v8a.
3. Import Nmap resource files (like nmap-services) to Android assets directory.

1. Migrate from deprecated AsyncTask to Runnable.
2. Explore options for IPC other than pipes and output redirection and remove ugly fork() in wrapper.
3. Add root support.
4. Add x86 and x86_64 support.
