I post my java code please find it below.

String ALGORITHM_MODE = "AES/GCM/NoPadding";
int TAG_LENGTH_BIT = 128;

Cipher cipher = Cipher.getInstance(ALGORITHM_MODE);
cipher.init(Cipher.ENCRYPT_MODE, secretKey, new GCMParameterSpec(TAG_LENGTH_BIT, iv.getIV()));
byte[] cipherText = cipher.doFinal(input.getBytes());
return bytesToHex(cipherText);
