Code: -25, Error: bad-txns-inputs-missingorspent

[Mike-bel]

This is my test code:(bitcoin wallet address:12UKAD8BBE3nBEVU9tgGRKvqfUmWwgVhBf)

public static void testSelf(Context context, String mnemonic) throws Exception {
  HDWallet wallet = new HDWallet(mnemonic, "");
  CoinType bitcoin = CoinType.BITCOIN;
  PrivateKey privateKey = wallet.getKey(CoinType.BITCOIN, "m/44'/0'/0'/0/0");
  PublicKey publicKey = privateKey.getPublicKeySecp256k1(true);
  BitcoinAddress address = new BitcoinAddress(publicKey, (byte) 0x00);
  // Logger.d("pk = " + ecKey.getPrivateKeyAsWiF(MainNetParams.get()));
  // Logger.d("publicKey = " + publicKey.description());
  Log.e("yf", "address = " + address.description());
  // 12UKAD8BBE3nBEVU9tgGRKvqfUmWwgVhBf
  String fromAddress = address.description(); 
  String toAddress = "1PoJZ1bjEEhMDYPsA4swWCmDE4eawzXqk";
  
  BitcoinScript script = BitcoinScript.lockScriptForAddress(fromAddress, bitcoin);
  byte[] prevHash = Numeric.hexStringToByteArray(new StringBuffer("0f5a9b3878e86cb7ed161c366b01f2fbef08369c43c97f6cfb30b62ef4959bf8").reverse().toString());
  Bitcoin.OutPoint outPoint = Bitcoin.OutPoint.newBuilder()
	  .setHash(ByteString.copyFrom(prevHash))
	  .setIndex(0)
	  .setSequence((int) Long.MAX_VALUE)
	  .build();
  Bitcoin.UnspentTransaction utxo = Bitcoin.UnspentTransaction.newBuilder()
	  .setAmount(1000)
	  .setOutPoint(outPoint)
	  .setScript(ByteString.copyFrom(script.data()))
	  .build();
  Bitcoin.SigningInput.Builder input = Bitcoin.SigningInput.newBuilder()
	  .setAmount(1000)
	  .setHashType(BitcoinSigHashType.ALL.value())
	  .setToAddress(toAddress)
	  .setChangeAddress(fromAddress)
	  .setByteFee(1)
	  .setCoinType(bitcoin.value())
	  .setUseMaxAmount(true)
	  .addUtxo(utxo)
	  .addPrivateKey(ByteString.copyFrom(privateKey.data()));
  
  Bitcoin.TransactionPlan plan = AnySigner.plan(input.build(), bitcoin, Bitcoin.TransactionPlan.parser());
  // Logger.d("plan fee = " + plan.getFee() + ", amount = " + plan.getAmount() + ", avail_amount = " + plan.getAvailableAmount() + ", change = " + plan.getChange());
  input.setPlan(plan);
  input.setAmount(plan.getAmount());
  
  Bitcoin.SigningOutput output = AnySigner.sign(input.build(), bitcoin, Bitcoin.SigningOutput.parser());
  if (output.getError() != null) {
	  Log.e("yf", "output error = " + output.getError().toString());
  }
  byte[] signedTransaction = output.getEncoded().toByteArray();
  Log.e("yf", "signed transaction = " + Numeric.toHexStringNoPrefix(signedTransaction));
}

this is the sign result:

01000000018fb9594fe26b03bfc6f79c34c96380febf2f10b663c161de7bc68e8783b9a5f0010000006a4730440220780f7fd39c47b290ba6bf15cba549e0d5dce0a385b730b5544f40a84aee829f90220378bd3b30c67acebf0df1e76f569a8729879a076fb5767a47bf23c587966daa20121036ed9a61ae998173a032f6fea0e80d59c909bfe4569e0529f3677279b1b4a9aabffffffff0128030000000000001976a914044fcd79c3c45c9ed5b6ff458e30c99f94398b5988ac00000000

when I broadcast the transaction by https://www.blockchain.com/explorer/assets/btc/broadcast-transaction, I get error like this:

"Code: -25, Error: bad-txns-inputs-missingorspent"

But I had set utxo into the input, so what is wrong, please?
