FCM Vs GCM? Why we need to migrate from GCM to FCM
<p>Hello Friends I am new to this stackoverflow community, but have wide experience in developing code using various programming languages like android. Today I was implementing GCM with one of my application, I was facing some problem of delay in push notification message.  I was reading about it on goggle and found somewhere that some new service named <strong>FCM</strong> launched by google recently. I read various article or blog but did not find much information from there. I have some questions in mind,  pls give your views, all stackoverflowian  are heartily invited to give their suggestion. </p>

<ul>
<li><p>Why we need this FCM.</p></li>
<li><p>FCM over GCM.</p></li>
<li><p>Is GCM now depreciated. Are they going to stop all services &amp; support
of gcm.   </p></li>
<li><p>How to update my old applications from GCM to FCM.</p></li>
<li><p>Can anyone show me the original link where google announced the FCM<br>
over GCM, because i did not found this originally posted google.</p></li>
</ul>
