Integer's max value is 2147483647.

try to use BigInteger for your hexadecimal.

BigInteger bigInt = new BigInteger(hexString, 16);

That number is larger than an int (Integer.MAX_VALUE is 231 - 1 or 2147483647). You could use a long like

System.out.println("Decimal value: " + Long.parseLong("A49D43C5", 16));

Output is

Decimal value: 2761769925
