Android Question Android headless units?

Alessandro71 · Sep 24, 2022

For an on-the-field data logging project, I'm looking for an Android device that can run B4A code with the following features:
1) black-box like form factor: no video required, able to fit a in car cockpit drawer
2) some physical buttons for start/stop of the logging app
3) USB connection for data capture
4) cellular connectivity
Anyone with some experience on a similar setup?
Does it even exist?

It does sound a lot like any Android phone.
I used a phone like this on a research project where it would text study participants on a schedule to query their status.
They would respond and the phone would log it.

The phone sat in a drawer for two years.
Once a day, we would take it out and plug it into our desktop to empty the log and handle
non-standard text responses.

I can only recall some old android phones have physical buttons for home, menu, back, etc. Some android phones targeting gamers also have physical buttons like up, down, left, right, etc. Also bluetooth connected gamepad for most of normal android phones is another option.

Maybe far-fetched but by attaching a usb-otg cable you can attach a keyboard or mouse to the android device.
Using a suitable Arduino with USB HID mode you can build your own keys.
