ADAS1000 linux driver with Android JNI

Hello,

We are working on an IoT based application for ECG monitoring with 10 leads and have connected ADAS1000 chipset with our single board computer through SPI. The device driver has been ported on the custom Android Nougat ROM as /sys/bus/spi/drivers/adas1000/spi0.0/iio:device0.

I'm writing an Android application with native JNI (using Android NDK) but not able to find the package I need to include in my JNI C++ file. It would be great if I can get a documentation for the JNI implementation. Also, a sample JNI code would help.

Thanks!
