Hi, @jasdel,
I have used and can recommend the Rode NT-USB Mini microphone: https://rode.com/en/microphones/usb/nt-usb-mini
It can be connected directly to an Android phone/tablet via USB-C. The sound it picks up is really excellent. The only thing that bothered me was that it picks up a wide area, so I had to use some kind of sound barrier.
That’s why I switched to a Zoom H1n audio recorder https://zoomcorp.com/en/us/handheld-recorders/handheld-recorders/h1n-handy-recorder/ , which can also be connected to an Android device via a USB cable. The initial setup, however, requires a bit of research and experimentation.
