I've bought a pair of 433MHz RF Tx Rx modules.

I've been struggling to find any information on getting them working on Android Things (Raspberry Pi).

My goal is to set up AT to detect the RF transmission upon a doorbell press and then notify my phone if i'm not in. I'm an Android dev so the software side doesn't phase me, but I'm new to IoT so any and all advice is more than welcome.

Given that Linux devices do process scheduling, the application in Android Things is not going to be able to reliably check the signal coming from a 433 MHz radio directly. It just isn't able to check at 433 million times each second.

But you can probably at some radio components to your receiver before it goes into your Android Things board, like an envelope detector, so that you can demodulate it to an extent and get a better digital input.
