Sorry @goenjoy because i haven’t explained it clearly, my model is shown below.
EDGE-V board running Android 9.0 and connect with MLX90640(IR Array Thermal Imaging Camera) through GPIO(shown below). My android app installed in EDGE-V. I want to get the return value from the MLX90640 through the Android app but I don’t know what to do. Please help me, @goenjoy.

First use I2C-tools tool to debug OK, and then replace the command line on Java.

You have to learn how to use I2C-tools tool. You can learn how to use on the Internet.
