Signature verification on Android 7

Question

In my app I need to verify a signature. An example is below. It works perfectly on Android 6 and older versions but just recently I noticed that it doesn't work on Android 7 or 8. When I run verifyData() I get this exception: java.security.SignatureException: error decoding signature bytes. at com.android.org.bouncycastle.jcajce.provider.asymmetric.util.DSABase.engineVerify(DSABase.java:82) at java.security.Signature$Delegate.engineVerify(Signature.java:1380) at java.security.Signature.verify(Signature.java:806)

What has been changed in these Android version that I don't know? How to verify signatures on Android 7 or later version?

        Signature signature = Signature.getInstance("SHA256withECDSA", "BC");
        signature.initVerify(pk);
        signature.update(data);
        return signature.verify(signatureBytes);
    }

    static PublicKey getPublicKey() throws Exception {
        Security.addProvider(new BouncyCastleProvider());
        Reader reader = new StringReader(PUBLIC_KEY);
        PemObject pemObject = new PemReader(reader).readPemObject();
        KeyFactory keyFactory = KeyFactory.getInstance("EC", "BC");
        X509EncodedKeySpec x509EncodedKeySpec = new X509EncodedKeySpec(pemObject.getContent());
        PublicKey key = keyFactory.generatePublic(x509EncodedKeySpec);
        return key;
    }

    static byte[] hexToBytes(String s) {
        int len = s.length();
        byte[] data = new byte[len / 2];
        for (int i = 0; i < len; i += 2) {
            data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
                    + Character.digit(s.charAt(i + 1), 16));
        }
        return data;
    }

}
