title: Can we send message to all registered user with Android GCM?
body: <p>I am using android GCM for sending push notification to all registered users but i am not able to send the message to all the registered users at once instead i have to write message separately for each user.So can this be replaced in such a way that on single click message is sent to all the users stored in database?? I am using PHP Script for this(Server Side). </p>
