## What it is
A small Android library with NDK/JNI native code for opening and reading/writing serial ports (RS-232/tty devices) on Android, plus a demo application. It was originally hosted on Google Code and has not been updated since 2015.

## Use cases
- communicate with serial devices from an Android app
- read data from RS-232 hardware on Android
- open /dev/ttyS0 on Android
- connect Arduino to Android via serial
- access tty serial port in Android NDK

## When to choose
- you need raw serial port access on Android with a minimal, proven native implementation
- you're targeting old Android versions and don't need recent maintenance

## When to avoid
- you need actively maintained code or support for newer Android security restrictions
- you want USB-serial adapters via the Android USB host API rather than native tty devices

## Facets
- artifact type: library
- maturity: abandoned
- function: sdk, file-system
- domain: android-tools, embedded-systems, hardware
- platform: cpp, c
- tags: serial-port, rs232, ndk, hardware-access, android
