Best way to decode Transaction's input

[stefanofornari]

Hello,
I want to retrieve and show all token transfer transactions for a given address. I get the transactions and I need to parse the raw input, which I understand is the result of the function:

Function: transfer(address dst, uint256 rawAmount) ***

MethodID: 0xa9059cbb
[0]: 000000000000000000000000652328ab1a9746e59d0995e8b5ae1de3f512bd6e
[1]: 0000000000000000000000000000000000000000000000000000000056e984ab

The raw Transaction's input data is:

0xa9059cbb000000000000000000000000652328ab1a9746e59d0995e8b5ae1de3f512bd6e0000000000000000000000000000000000000000000000000102a7121cb5ce2a

I found the class org.web3j.abi.FunctionReturnDecoder and it seems to be helpful to parse the parameters, but it breaks if I use the full input (where the first 4 bytes are the function).
Is there in web3j a good way to parse the entire raw data? Or shall I use FunctionReturnDecoder stripping the leading bytes?

Many thanks in advance.
