Re: [android-developers] Android GCM without a 3rd party server (Device to Device push notification without 3rd party server via GCM)
Yes, I believe we are talking about the same key (I did only a brief check on GCM documentation and thought it's called Sender Id, my bad). Still, I am not exactly sure how Google reacts if/once you start sending push notifications from multiple IPs. I tend to think people are usually limiting the IP space allowed to send notifications instead of depending on no filtering takes place at all. But if this is not an issue, I see absolutely no reason why this couldn't work. -- H On Jul 8, 2014 8:39 PM, "MS" wrote: > Hi Harri Smatt, > > Sender Id needs to be in the App to register with GCM server and get the > GCM ID.

Further to that. . as soon the APK register the device it gets the RegistrationId which inturn store in the Server DB so that the Server can push the messsage. for example; https://myserver/api/updategcmdata driverid=2113 registrationid=x The service will update/create the new record in the DB.

Re: [android-developers] Android GCM without a 3rd party server (Device to Device push notification without 3rd party server via GCM)
@Haris.. You would need to store the GCM- Registration Id in the Database(Server side) so that the Server API/Webservice api/ should able to pick the Registration Id from the DB and send me message to the correct device (Based on the registration id). here is the way i used it. I have an logistics app where in the Admin decide the take a load or do a refresh upon receving the GCM Message. The server db is having a GCM table with the following structure. RegistrationID | DriverId | Message | Status|. xxx | 2113 | Refresh | 1 The data will be pulled by the HTTP request which inturn send the message to the device so that Driver get to know that there is a updated data and it requires to download after downloading the data the APK will update the status back to 3 so that the HTTP request should not pull the same record.

Re: [android-developers] Android GCM without a 3rd party server (Device to Device push notification without 3rd party server via GCM)
Hi Harri Smatt, Sender Id needs to be in the App to register with GCM server and get the GCM ID. I believe you are referring to GCM API key. We will be encrypting the GCM API Key in our app. On top of that we will be using DexGuard to obfuscate the code. And more over sending message to GCM is an *HTTPS *call. Considering all the above, we think that it should be secure enough. Thanks a lot for your reply. Do you foresee any other issues?

[android-developers] Android GCM without a 3rd party server (Device to Device push notification without 3rd party server via GCM)
We are writing an Application that will exchange messages between users extensively. We are using Google App Engine *The traditional way *is to have an Application Server that stores all the GCM_ID of the users. So if User 1 wants to send message to User 2, then 1. The User 1 sends the message to Application server with payload which contains message and recipient id (User 2 in our case) 2. The application server retrieves the GCM_ID of User 2 and with the help of sender API pushes the message to User 2 3. User 2 receives the message *What we implemented:* Now as the number of users and app usage increases ( We hope it does :) ), the costing related to AppEngine w.r.t number of instances, no. of read/writes etc increases. We want to reduce this costing. Since pushing message to GCM server is a REST Call (via https://android.googleapis.com/gcm/send) , we came up with the idea of storing GCM_ID's of user's friends in the Android App (DB to be specific) & were able to push messages from one user to another. So instead of a server having all GCM_ID's we are exchanging relevant GCM_ID's related to users via server and storing them in App DB We also have designed the app to take care of change in GCM_ID of another user, Un-installation of App etc.. Are we missing anything by not choosing to push via our own server? Is following such an implementation correct?
