[Android] Unlock script hash is incorrect after btc signature

Describe the bug
Unlock script hash is incorrect after bitcoin signature

I am going to send a transaction from the P2PKH address to the Bech32 address, but the hash of the unlocking script is incorrect.

from 1HQ3rb7nyLPrjnuW85MUknPekwkn7poAUm to bc1qceyq9k3uer7m2qa6zf9z3rxjzxa95k5pknmjja

HDWallet wallet = new HDWallet("army van defense carry jealous true garbage claim echo media make crunch", "");
CoinType bitcoin = CoinType.BITCOIN;
PrivateKey privateKey = wallet.getKey(CoinType.BITCOIN, "m/44'/0'/0'/0/0");
ECKey ecKey = ECKey.fromPrivate(privateKey.data());
PublicKey publicKey = privateKey.getPublicKeySecp256k1(true);
BitcoinAddress address = new BitcoinAddress(publicKey, (byte) 0x00);
Logger.d("pk = " + ecKey.getPrivateKeyAsWiF(MainNetParams.get()));
Logger.d("publicKey = " + publicKey.description());
Logger.d("address = " + address.description());
// 1HQ3rb7nyLPrjnuW85MUknPekwkn7poAUm
String fromAddress = address.description();
String toAddress = "bc1qceyq9k3uer7m2qa6zf9z3rxjzxa95k5pknmjja";

BitcoinScript script = BitcoinScript.lockScriptForAddress(fromAddress, bitcoin);
byte[] prevHash = NumericUtil.reverseBytes(ExtensionsKt.hexStringToByteArray("5932892f8dba160ed3608130083e4fc6f747b5113c12f4a2e7cf3376ca3291c9"));
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(750)
        .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) {
    Logger.e("output error = " + output.getError().toString());
}
byte[] signedTransaction = output.getEncoded().toByteArray();
Logger.d("signed transaction = " + Numeric.toHexStringNoPrefix(signedTransaction));

the binary data:
0100000001c99132ca7633cfe7a2f4123c11b547f7c64f3e08308160d30e16ba8d2f893259000000006a47304402206c4b600c7251a8ab26e13ad6c9d4a0ba8e479582946f37c990e986ca57d8877c0220363778d7487a7b06a37fabe8d8b3f8a79babcbd57bd65d09c83d788037f7e1bd0121036740c4f55d64fb6c9bc412084638b80062cee07f6c84b205671584e82a7c96b7ffffffff012b03000000000000160014c64802da3cc8fdb503ba124a288cd211ba5a5a8100000000

Is this the same as #1365 ?

Hi, this problem is not the same problem as #1365 problem. I have solved the #1365 problem. The problem encountered now is signed by me. The problem now is unlock script hash is incorrect, and ios also encountered the same problem.

Hi,
Someone solved this in android ?
