AES Encryption (AES/ECB/NoPadding)

Question

i want to encrypt some data through AES Algorithm. For iOS i'm using AESCrypt Library and for Android i'm using Cipher Library but i am not the same result although it's the same algorithm we're talking about here. Any Help would be appreciated

iOS Code :

NSString *encryptedData = [AESCrypt encrypt:message password:password];

Java Code

public static String encryptMethod(String seedBase64, byte[] key) {
    try {
        byte[] seed = Base64.decode(seedBase64, 0);
        SecretKeySpec keySpec = new SecretKeySpec(key, "AES");
        Cipher cipher = Cipher.getInstance("AES/ECB/NoPadding");
        cipher.init(1, keySpec);
        return Base64.encodeToString(cipher.doFinal(seed), 0);
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

Sometimes there are issues with the padding on different platforms so the result differs, i would recommend using some cross platform library like this one. https://github.com/Pakhee/Cross-platform-AES-encryption
