I am trying to develop an application using bitcoinj library. I want to get the bitcoin transaction details.
The details, that I want to extract from a transaction includes the following.
1) Who send me the transaction (Address and Public Key of the sender).
2) The amount that I received.
3) When was the transaction issued.
4) Get the data stored in the transaction in OP_RETURN.

maybe this helps
private void txHistory()
{
List<Transaction> txx = kit.wallet().getTransactionsByTime();
if (!txx.isEmpty())
{
int i = 1;
for (Transaction tx : txx)
{
System.out.println(i + " ________________________");
System.out.println("Date and Time: " + tx.getUpdateTime().toString());
System.out.println("From Address: " + tx.getOutput(1).getAddressFromP2PKHScript(params));
System.out.println("To Address: " + tx.getOutput(0).getAddressFromP2PKHScript(params));
System.out.println("Amount Sent to me: " + tx.getValueSentToMe(kit.wallet()).toFriendlyString());
System.out.println("Amount Sent from me: " + tx.getValueSentFromMe(kit.wallet()).toFriendlyString());
long fee = (tx.getInputSum().getValue() > 0 ? tx.getInputSum().getValue() - tx.getOutputSum().getValue() : 0);
System.out.println("Fee: " + Coin.valueOf(fee).toFriendlyString());
System.out.println("Transaction Depth: " + tx.getConfidence().getDepthInBlocks());
System.out.println("Transaction Blocks: " + tx.getConfidence().toString());
System.out.println("Tx Hex: " + tx.getHashAsString());
System.out.println("Tx: " + tx.toString());
i++;
}
}
else
{
System.err.println("No Transaction Found");
}
}
There is no single "sender" address in Bitcoin, a transaction may be funded from balances of multiple addresses. – Murch – 2016-06-13T15:44:59.223
