问题 Note, this question should be materially different from other questions with a similar name because of the fact that the API seems to have changed significantly over the past few years. I am trying to send a push notification to an iOS device using GCM. I have (I think) mostly set it up correctly. I have an API key from GCM, I've setup my SSL certificate on Apple Developer and I have my device correctly getting a registration id. I've got a little test script written up to try to test it and

问题 this is my first question in here, sorry in advance if something is not ok in my question! I'm currently using Xamarin in Visual Studio 2013 on a MacBook, I created a PCL project and I created all the things necessary to make the push notifications work for iOS and Android . Using a simulator and also a real device I can achieve both with a server side program where I use the device token created from the client side. Everything worked fine for a couple of hours but after a while both the

问题 Edit: I solved this problem:) Cause of this error : In the tutorial Implementing GCM Client , there was link to download full source code for demo. Downloaded for reference , added google_play_service library in build.gradle. Did some recommended changes like SENDER_ID,SERVER_URL,.. etc Synch the project with gradle and got this error. How I solved! After lot of google I found that this class is not in google_play_service library but it is in gcm.jar which is deprecated now. I dont know why

问题 I have GCM notification implementation. I know that the client application receives the notification whether it is in the foreground, background or killed state. What I would like to know is, how can I launch my application on notification received, when the application is in the killed state? 回答1: In the message receiver, I do the following: final Intent notificationIntent = new Intent(context, YourActivity.class); notificationIntent.setAction(Intent.ACTION_MAIN); notificationIntent

问题 I am making a chat application for android. For that, I decided to use GCM (Google Cloud Messaging). But having researched a bit about it,I have read that it shouldnt be used for something like chat. I will be implementing Upstream messaging (sending data from the device to the GCM directly, without a send-to-sync). Here are my concerns: Will the messages transfer instantly? (will be fast enough that the user can see 'typing'/seen) If all devices are online, what is the guarantee of the

问题 I'm using the new google cloud messaging (GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance (context);) I am following this example, which is very good and works perfectly: https://github.com/commonsguy/cw-omnibus/tree/master/Push/GCMClient2 With this example I can register in the GCM, but I tried unsuccessfully to unregister. in the documentation indicates that you should use the following intent: com.google.android.c2dm.intent.UNREGISTER And use it as follows: Intent unregIntent =

问题 I have a problem related to time_to_live . I get messages when the device is on, but when it is offline I don't get the message or at least it is not sent in the first 15 minutes. I'm sending the message with delay while idle true and time_to_live 2419200. Any ideas what is happening, maybe I misread the documentation. 回答1: From the documentation : delay_while_idle : If included, indicates that the message should not be sent immediately if the device is idle. The server will wait for the
