How to set large icon for GCM notification
<p>In <code>GCM 3.0</code> notification when the app is in background will be handled by <code>GCM SDK</code> itself. But I am Unable to set the Large icon the the notification created when the app is in background.</p>

<pre><code>{
    "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification" : {
        "body" : "great match!",
        "title" : "Portugal vs. Denmark",
        "icon" : "myicon"
    }
}
</code></pre>

<p>The <code>myicon</code> sent here is displayed as the small icon. </p>

<p>Is it possible to set large icon for notification when the app is in background?</p>
