Verify Bitcoin Transaction Following the great post [Redeeming a raw transaction step by step example required, I came up with  code below but the verification failed.

// pubkeyBytes, len: 65

// data, len: 32
// 30f10a6468b7d98257af63fb40dfcf2cefe991346fd37c67cf7b51ff8d4404d3

// signatureBytes, len: 71

    ECPublicKey publicKey = (ECPublicKey)KeyBuilder.buildKey(KeyBuilder.TYPE_EC_FP_PUBLIC, KeyBuilder.LENGTH_EC_FP_256, false);;
    Secp256k1.setCommonCurveParameters(publicKey);
    publicKey.setW(pubkeyBytes, (short) 0, (short) pubkeyBytes.length);

    Signature eccSign = Signature.getInstance(Signature.ALG_ECDSA_SHA_256, false);
    eccSign.init(publicKey, Signature.MODE_VERIFY);
    boolean verified = eccSign.verify(data, (short)0, (short) data.length,
                signatureBytes, (short)0, (short)signatureBytes.length
            );
    Assert.assertTrue(verified);


Assertion failed at the end. 

Have been stucked for hours. Cannot figure it out. Any help is highly appreciated. Thanks.

  qDebug ( ) &lt;&lt; ( digest.verify ( pubkey, signat ) ? "passed" : "failed" );
}


my result is:: passed

the signature is correct for digest and public key

may be something is wrong in your verification code with decoding hex values and/or byte order in digest?
