```
 abstract void setDeviceFingerPrint(@NonNull() Transaction transaction, @NonNull() OppPaymentProvider provider, @Nullable() CheckoutInfo info, @NonNull() FingerPrintListener listener)
```
    Collects the device fingerprint and applies it to transaction's payment params, then reports the (possibly enriched) transaction back through listener.
    Implementations must always invoke the listener — on success with a null error, on failure with a com.oppwa.mobile.connect.exception.PaymentError — so the caller's payment flow is never blocked by a fingerprinting failure.
    
    Parameters:
    
    transaction - the transaction to enrich
    
    provider - the payment provider
    
    info - the already-loaded checkout info, or null to fetch it via provider
    
    listener - the completion callback
