I would like to know how the android market initiates the remote download through their website. I'm guessing there is some sort of push notification system. I want to know if it's possible to do the same thing using a different web interface.
The only possibility I see is to use the C2D (Cloud to Device) messaging API provided by Google. In that way you could send an install intent to the device. However that would always open the market locally on the device from which the user can then install the app.
Obviously Google can bypass these "limitations" :)
They use Android Cloud to Device Messaging (C2DM). They allow anyone with a server of their own to implement this service.
From the site:
Android Cloud to Device Messaging (C2DM) is a service that helps developers send data from servers to their applications on Android devices. The service provides a simple, lightweight mechanism that servers can use to tell mobile applications to contact the server directly, to fetch updated application or user data. The C2DM service handles all aspects of queueing of messages and delivery to the target application running on the target device.

we have a web application using responsible html, it is seamlesly usable from mobile browsers...
We would like to send "event" (push notification) to users phones (device!). Standard notification with icon of our app and short text. Pending intent would be just open our web application in browser (URL).
So, question is how to do this without need of client application installed on target phone which would provide registration of such device (send it to our server, who will use it later to let firebase to notify such device).
Is it possible to create a device registration from browser (chrome)? Either to google account used in device or ask to fill it ...
How are web notification related? If I understood it correctly, a page with our app needs to be opened to receive web notification. What about instant apps?
Yeah, we could create a very simple application which would be linked (google play) from our web application - which would provide JUST registration a receiving of push notification. And than just open a browser. But it looks to me as unnecessary, because push client is part of android system. The only what we need to send device ID to our server...
Thanks for any idea. Ideally, a link to documentation or proof-of-concept on github (-: because I believe it is a standart situation.
PS: And sure, as always, at the end we would like to have it multi platform. And no, we prefer not to use non-system providers like pushy ...
I've built an Android application by android studio.
I want to be associated with users online and notify changes and news.even when my application is closed.
This is what is on my mind,I have web server, i want create a internet connection listener and when connection is available,application or a part of it connect with the server and get new information and notify the user with a notification.even when my application is closed.
How can I implement and enforce it?
Try "Google Cloud Messaging."
Per their Developer Console Help page: "Google Cloud Messaging (GCM) is a free service that helps developers send messages across multiple platforms: Android, iOS, and Chrome. For example, a server can send messages directly to single devices, groups of devices, or devices subscribed to topics. Also, the application on a device can send messages directly to a server and to devices belonging to the same group."
Use the Google Cloud Messaging service alongside the Google Plugin for Eclipse. Google Cloud Platform explains as: "When targeting Android devices, it is easy to get started by using Google Plugin for Eclipse (GPE). GPE allows you to generate an App Engine Connected Android Project that provides the basic logic needed for sending push notifications using Google Cloud Messaging for Android from a mobile backend running on Google App Engine."
This could send messages for you without having to do the work on your own server. If this answer helped you, please consider up-voting or accepting it as the answer. Thanks, and best of luck on your project!
No,These systems are always some limitations and managed with others.I do not need to communicate with iOS or chrome ,I need to design a system that's all for me.Experience has shown me great services, such as Google services and any other company affected by political issues.for example i live in iran right now.
All production-oriented and knowledge-based services for this country is banned.
due to this problems i prefer to have my own messaging and notification system.
I am developing an server based Android app in which i have to notify user. Please suggest me some techniques to do this. How do Whatsapp, Facebook notifies the user?
As a suggestion , you need
Server to run web application
web application to register and send notifications to devices where your app installed.
client / server keys registered with Google Cloud Messaging API
to perform this
I'm making a NodeJS server and an Android app that goes with it. I need to send alerts to my mobile app users that's coming from the web server. Something like a a chat app on the server and the android users getting the messages also (Facebook messenger?).
I have the server ready and Android app communicating to its database (for user login/getting user info/etc) using REST. I just need to figure out how to send info to the Android app WITH THE SERVER INITIATING COMMUNICATION. Any advice on where to start?
Start by looking at Google Cloud Messaging.
It's a free service that accepts messages from your server-based program and queues it to be sent to phones with your app when the phones are online.
Here is the overview on Android Developers.
YES!
Working with NodeJS, you have probably already heard of Socket.IO.
I'd say: Start there!
For your app to communicate with the server, there's also the java lib. These are great tools to start making any good real time service.
After you get along with this, you should also check GCM as #krisLarson suggested. And talkign about GCM, you have Node-GCM to make your work even easier.
Good luck!
I was just looking at the new Google Cloud Messaging (GCM) and I was wondering if it is possible to use GCM for Instant Messaging on your Android application?
I saw you can send data, like a message, from a server, but is it also possible to send from one device to another one?
And how would this work?
Some example code would be really helpful..
Tnx!
The official docs on Google Cloud Messaging for Android does mention that GCM can be used to develop an instant messaging app.
...or it could be a message containing up to 4kb of payload data (so
apps like instant messaging can consume the message directly).
So we went ahead and created an instant messaging app using GCM. The server-side is powered by Google App Engine. You can read the complete tutorial here. Create an Instant Messaging app using Google Cloud Messaging (GCM)
So it is possible to use GCM for Instant Messaging on Android, to answer your question. However, reliability of GCM compared to XMPP for IM is another topic.
Just my two cents:
I think you should not use GCM for delivering IM. You should have a dedicated server where your Android IM apps will connect to, using a persistent socket connection. Your server will know who is online or not and therefore can present an 'online list' to all the apps.
GCM can come into play, while users are offline or not running your app. A GCM message can be sent to them to indicate 'XXXX wants to chat'. They can then launch your app and automatically connects to a chat session.
Google has said that the delivery of GCM messages are not guaranteed. This reason alone is not a good idea to rely on them for Instant Messaging.
Try pub nub - it is pretty easy to implement - send Im from one mobile to another - simply fire up the web page (see link) in the browser , and chat between pc, mobile - and works - with 'no server'. Code is for javascript but they also have java. Chat app using jquerymobile web app framework
You might want to check out how a server sends a message to the GCM Service. It is possible to use php on Server side so it should be possible to adapt that to a POST request directly out of your application. However, to communicate you need the registered ids of the devices you want to send data to. Means you will need something to store and get them. Best solution would be your own (web) server which stores all ids and handles the Message sending.
