BSP - Support Support Package. This contains board-specific code, i.e. MCU core + MCU Periherals + specialized peripheral devices (boards).
Android is based on the Linux kernel for ARM, so there is Android for ARM. But, of course, you want to port it for specific MCUs and peripherals. If you can base your design on a board that already has an Android port, or at least a MCU that Android is already ported to, you will save a lot of time.
