php mcrypt_encrypt加密与android AES-128加密不匹配

我需要对所有api请求和响应进行加密，我正在使用以下代码。但php代码的加密值和android生成的不匹配。

function encrypt($input,$key) {
     $size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC); 
     $input = $this->pkcs5_pad($input, $size); 
     $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, ''); 
     $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND); 
     mcrypt_generic_init($td, $key); 
     $data = mcrypt_generic($td, $input); 
     mcrypt_generic_deinit($td); 
     mcrypt_module_close($td); 
     $data = base64_encode($data); 
     return $data; 
}
function aesdecrypt($sStr,$sKey){
    $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, ''); 
     $iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND); 
    $decrypted= mcrypt_decrypt(
        MCRYPT_RIJNDAEL_128,
        $sKey, 
        base64_decode($sStr), 
        MCRYPT_MODE_CBC
    );
    $dec_s = strlen($decrypted); 
    $padding = ord($decrypted[$dec_s-1]); 
    $decrypted = substr($decrypted, 0, -$padding);
    return $decrypted;
}

安卓代码（用于加密和解密）：

public static String encode(String password, String text)
        throws NoPassGivenException, NoTextGivenException {
    /*if (password.length() == 0 || password == null) {
        throw new NoPassGivenException("Please give Password");
    }
    if (text.length() == 0 || text == null) {
        throw new NoTextGivenException("Please give text");
    }*/
    try {
        SecretKeySpec skeySpec = getKey(password);
        byte[] clearText = text.getBytes("UTF8");
        //IMPORTANT TO GET SAME RESULTS ON iOS and ANDROID
        final byte[] iv = new byte[16];
        Arrays.fill(iv, (byte) 0x00);
