There is nothing new about this topic. For most small and medium-sized companies, it is generally a choice for third-party services. But now there are a lot of companies and products that offer push services, how do you choose a service that suits your project? What's the difference between them? Here for you to do a simple research, hope can help everyone.
Brief introduction:
mobile phone Push service refers to the service that the server directs the information to the phone in real time. Push service , The main is the latest information and recent activities to the user in time , to maintain interaction with users , thereby increasing user stickiness to improve the user experience. For example , a notification bar message for apps such as Sina Weibo.
Principle:
1) polling method: The application should periodically connect with the server and query whether there are new messages arriving, you must implement the communication with the server, such as Message Queuing. And you also have to consider the frequency of polling, if too slow can cause some message delay, if too fast, it will consume a lot of network bandwidth and battery.
2)SMS (Push) mode: on Android platform, you can intercept SMS Message and parse the message content to understand the server's intentions and get its display content for processing. This is a good idea and I've seen applications that use this scenario. The benefit of this scenario is that full real-time operations can be achieved. But the problem is that the cost of the solution is relatively high, and we need to pay the cost to the mobile company. It is difficult to find a free short message sending gateway to implement this scenario.
3) Persistent connection (Push) mode: This solution can solve the performance problems caused by polling, but still consumes the battery of the phone. The push service for the IOS platform works well because each phone only maintains a connection to the server, and in fact C2DM works. But just now, there are a lot of shortcomings in this solution, that is, it is difficult for us to achieve a reliable service on the mobile phone, and currently can not be compared with The push function of the IOS platform.
after understanding the principle of our small and medium-sized companies such as the development of their own push service is still relatively high cost, time cost is relatively high. For rapid development, we typically select third-party push services.

domestic common solutions:
One , mqtt protocol implementation push function
The use of the MQTT protocol for Android Push is also a solution. MQTT is a lightweight message publishing / Subscription protocol that is the ideal solution for implementing a messaging push server based on a mobile client.
Wmqtt.jar is an implementation of the MQTT protocol provided by IBM . We canDownload The instance code of the project from here (Https://github.com/tokudu/AndroidPushNotificationsDemo), and we can find a PHP server-side implementations of writing ( https://github.com/tokudu/PhpMQTTClient ).
The schema looks like this:
<ignore_js_op>
Wmqtt.jar is an implementation of the MQTT protocol provided by IBM . We can download it from the following site (http://www-01.ibm.com/support/docview.wss?rs=171&uid=swg24006006). We can add the jar Package to our Android app.
-------------------------------------------------
Second,rsmb realize push function.
really Small Message Broker (RSMB) , he is a simple MQTT agent, also provided by IBM , Its view address is:http://www.alphaworks.ibm.com/tech/rsmb. Opens the 1883 port by default, which is responsible for receiving messages from the server and forwarding them to the specified mobile device.
SAM is a PHP Library written for MQTT . We can download it from this http://pecl.php.net/package/sam/download/0.2.0 address .
send_mqtt.php is a message that receives messages via POST and sends messages to RSMB via the SAM PHP script.

Third,theXMPP protocol to achieve Android push function
XMPP ( extensible Communication and Presentation Protocol ) is an Extensible Markup Language (XML)-based protocol that is used for instant messaging (im ) as well as on-line probing. The agreement may eventually allow Internet users to send instant messages to anyone else on the Internet.
Androidpn is an XMPP Protocol- based Java Open-source Android push Notification implementation. It contains the full client and server side.
This is ANDROIDPN 's project. Home:http://sourceforge.net/projects/androidpn/
The ANDROIDPN implementation intent is as follows: <ignore_js_op>
These are the most popular solutions, but they all have some difficulty and realize the cost. Here I mainly introduce the third-party platform for fast solutions.
Third-party platform services for push functionality:
in the survey, third-party push service has more than three. Four main push platforms are recommended below.
A push
<ignore_js_op>a push is by the domestic letter Interactive Network Technology Co., Ltd. launched a platform to help enterprises in the application through the low-cost Internet channel for message push, to provide a sound, efficient and stable service system, to solve the internet cloud to the mobile phone side of the message interoperability problem, relying on the already mature push technology, To establish a more stable and market demand for a standardized service platform.
Featured Features:1, stable and efficient: Single Server concurrent support 200-400 million, the industry leader; push delivery rate up to a few million / Second, Message arrival rate 96% above; multiple apps Merge a long connection and share the link. 2, a push can not only provide cloud-to-Client push service, also can provide from the client upload to the cloud service, that is, push message link support up and down two-way channel, developer and client interaction more convenient. 3. Support Incremental UPDATE: When the developer submits a new version of the APP on the back of the platform , a push can be pushed to the user to notify the new version, the user just download the difference portion of the file, improve the update rate and product experience. 4. Support Rich media push
---------------------------------------------------
Aurora Push
<ignore_js_op>Aurora Push, abbreviated Jpush, is an open, partially free, third-party message push service for ordinary developers. Aurora Push enables developers to instantly push notifications or messages to users of their applications to stay in touch with users, effectively improving retention and improving the user experience. The platform offers a unified push service that integrates Android push andIOS push.
Featured Features:1, flexible push target, can be pushed to specific individual users.
2. support Rich media push
3, relatively stable, high efficiency
-----------------------------------------------------
Baidu Cloud Push Send
<ignore_js_op>Baidu Cloud Push (push) is Baidu's open cloud to the developers to provide the message push service, by leveraging the cloud and the client to establish a stable, reliable long connection to provide developers with the application of push real-time messaging service to the client. Baidu Cloud push service supports the push of three types of messages: notifications, through-stream messages, and rich media; supports push messages to specific groups of users or categorized by tags.
Featured Features:1, multiple apps Merge a long connection, share the link.
2, In addition to the user group and tags in the push strategy (positioning function).
3, Baidu account system support (Baidu account login)
4. small SDK size
5. Support Rich media push
------------------------------------------------------
Friend League push
<ignore_js_op> Friends League is the most professional and data-cohesive mobile developer service platform in China, which was created in Beijing in 4 months. Friends of the mobile application of statistical analysis as the starting point of product development into a comprehensive mobile developer service platform. Friend Alliance Push is a service that helps you proactively push your app's content updates or activity notifications to end users, giving them the first time to get relevant information and effectively improve user activity and retention rates.
