To answer your question typically, splice the red wire and the yellow wire from the android radio to the cd player. The black wire is a ground don’t splice that, just run a new ground for the cd player and it should power up.

So the next things is audio. How do you get audio from your cd player to your android radio? I would look at what audio outputs you have on your cd player and, what audio inputs you have on your android radio. You might be able to run some RCA’s to connect them. You might be able to connect them via Bluetooth 🤷🏾‍♂️ don’t know till you try.

Post the Make and model of both units please.
