Offline creating raw transaction and sign on device.

[Constantine Stanev]

Hello, I tried create a raw transaction and sing it without connection to peer and blocks synchronization. 

But I've getting error "Error validating transaction: Error running script for input 0 referencing 3615d7ecabe9f8f2788e5d78d1399692df3e7bf54ab89b0b4a807ffabcb94179 at 0: Script was NOT verified successfully.." while broadcasting transaction on  https://live.blockcypher.com/btc-testnet/pushtx/

I spent this week looking for a possible error, and look on other open source projects, but I did not find any clue. 

I will be very grateful for the help, thanks.

There is my code:

Address fromAddress = wallet.currentReceiveAddress();// mtTvAK7vLFVUEWMuMMvK6Gmp6sxbjZPKjf
Address receiver = Address.fromBase58(params, "mysBqTUdJTLLw95x9eyc8QApFRkJXErD8R");
List<UTXO> utxos; // I get UTXOs from custom API service

DumpedPrivateKey dumpedPrivateKey = wallet.currentReceiveKey().getPrivateKeyEncoded(params);
ECKey key = dumpedPrivateKey.getKey();
Transaction tx = new Transaction(params);
tx.addOutput(Coin.valueOf(amount), receiver);

for(UTXO utxo : utxos) {
    TransactionOutPoint outPoint = new TransactionOutPoint(
            params,
            utxo.vout,
            Sha256Hash.wrap(utxo.txid)
    );
    tx.addSignedInput(outPoint, new Script(hexEncoding.decode(utxo.scriptPubKey)), key);
}

tx.getConfidence().setSource(TransactionConfidence.Source.SELF);
tx.setPurpose(Transaction.Purpose.USER_PAYMENT);

tx.verify();

byte[] ser = tx.unsafeBitcoinSerialize();
String finalHex = hexEncoding.encode(ser);
System.out.println("RESULT  "+ finalHex); //And here I am try to broadcast it on https://live.blockcypher.com/btc-testnet/pushtx/
