solana spl token transfer

[HemangiVekaria]

I am using this library in Android app for solana wallet. I used this for native SOL token transfer and it's working. But now i want to use this same library for Solana SPL (USDC,etc) token transfer. But have no idea when to pass this programID while writing SystemProgram.transfer() and then signing transaction using

transaction.sign(Arrays.asList(signer));
transaction.serialize().

Can anyone help please?
