How does one use TrafficStats.incrementOperationCount()?
<p>The documentation for  <a href="http://developer.android.com/reference/android/net/TrafficStats.html#incrementOperationCount%28int,%20int%29" rel="nofollow"><code>TrafficStats.incrementOperationCount()</code></a> says:</p>

<blockquote>
  <p>Increment count of network operations performed under the given
  accounting tag. This can be used to derive bytes-per-operation.</p>
</blockquote>

<p>I want to find the total number of bytes transferred during a particular network operation. Since this API claims to help in deriving bytes-per-operation, can someone help me understand how to use it?</p>
