Aes gcm nopadding in php

I am trying to use AES-256 bit GCM encryption, between PHP and Java. The problem is that I receive this exception on Java side on Android:

Decryption Error.!
javax.crypto.AEADBadTagException: error:1e06e065:Cipher functions:aead_aes_gcm_open:BAD_DECRYPT

the code I am using: on PHP side

$algo = 'aes-256-gcm';
$iv   = random_bytes[openssl_cipher_iv_length[$algo]];
$key  = "secretKey12345678998765432112345"; // 256 bit 
$data = "HelloWorld";
$ciphertext = openssl_encrypt[
 $data,
 $algo,
 $key,
 OPENSSL_ZERO_PADDING,
 $iv,
 $tag
];
echo base64_encode[$key];
echo base64_encode[$iv];
echo $ciphertext;

and on Java, Android, I am using this code:

static final int GCM_TAG_LENGTH = 16;
...
String decryptedText = null;
    byte[] encodedData = Base64.decode[data, Base64.DEFAULT];
    byte[] decodediv = Base64.decode[iv, Base64.DEFAULT];
    byte[] decodedKey = Base64.decode[key, Base64.DEFAULT];

    Log.e["data", new String[encodedData, 0]];
    Log.e["iv", new String[decodediv, 0]];
    Log.e["key", new String[decodedKey, 0]];
    Log.d["test", "test"];

    SecretKey originalKey = new SecretKeySpec[decodedKey, 0, decodedKey.length, "AES"];

    try {
        Cipher c = Cipher.getInstance["AES/GCM/NoPadding"];

        c.init[Cipher.DECRYPT_MODE, originalKey , new GCMParameterSpec[GCM_TAG_LENGTH * 8,decodediv]];
        byte[] decodedData = c.doFinal[encodedData];
        decryptedText = new String[decodedData, "UTF-8"];
        Log.e["MainActivity", "After decryption : "+ decryptedText];
    } catch [Exception e] {
        Log.e["MainActivity", "Decryption Error.!", e];
    }
    return decryptedText;

I am using php code from this page:

zimuel.it/blog/authenticated-encrypt-with-openssl-and-php-7-‌​1

I am using php v7.1.4

What could be the exception cause?
