Hi Andreas.
Thanks so much for your reply and direct.
I understand that a pending transaction alone doesn't guarantee much.
Normally, we will monitor the transaction directly by the blockchain
explorer or by our wallet automatically (if the txouts point to the address
owned by our wallet). However, in my situation, I have to sync and collect
the confidence future of tranctions which doesn't have direct connections
with my wallet.
I thought that I just got the pending transaction. I can re-broadcast the
trasaction and add some listeners to finish this.So I do following things:
Transaction authTx = new Transaction(bitcoin.params(),txBytes);
bitcoin.peerGroup().broadcastTransaction(authTx);
bitcoin.wallet().commitTx(authTx);
Main.bitcoin.peerGroup().addBlocksDownloadedEventListener(new
BlocksDownloadedEventListener() {........}
authTx.getConfidence().addEventListener(new TransactionConfidence.Listener()
{...........}
However, nothing happens and works. The world is silent. I just got these
notations:

After this, the world is silent. However, the tx has been received by the
blockchain in the next few minutes. But my wallet sync and monitor nothing.
Does my code lack important settings or the thought and approach is totally
wrong?
