SendTransferResponse successfully is true, but the Block browser is not found

[EmilyChf]

code :
List transfers = new ArrayList<>();
transfers.add(new Transfer("test address1", 10, Constant.MESSAGE, Constant.TAG));
List inputList = new ArrayList<>();

    Input input = new Input("test address2", 1000, 1, 2);
    inputList.add(input);
    SendTransferResponse str = rpc.api.sendTransfer("seed2", 2, Constant.DEPTH, Constant.MIN_WEIGHT_MAGNITUDE_SPA, transfers, inputList, null, false, true, null);

I use the spamnet sites, because the devnet websites that get free tokens can't open
