Checksum calculation in android/java
<p>I wrote a checksum calculation function in android/java.  the function as follows</p>

<pre><code>void CalculateCheckSum( byte[] bytes ){
     short CheckSum = 0, i = 0;
     for( i = 0; i &lt; bytes.length; i++ ){
        CheckSum = (short) ((short)CheckSum + (short)bytes[i]);
     }

     Log.i("Checksum", Integer.toHexString(CheckSum));
}
</code></pre>

<p>input values for calculation of checksum are 0xEF, 0x01, 0xEF, 0x01, 0x33, 0x0C, 0xB8, 0xE5, 0xFC, 0x34, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF.  I manually calculated the checksum value and result is 0xCE4.  When using the above function i get answer as 0xFFFFFFE4.  Is any error in my calculation, if yes then please correct me.</p>

<p>thanks </p>
