Visit androidpn official site , we can understand the following basic information:
androidpn full name is Android Push Notification.
This is the Korean source on an open source project on sourceforge.net , the document is in Korean .
recent version of the update time is 2010-11-05 , which is about two years ago .
visits from China , accounting for 81% of total visits . Please click on this link to look at the current statistics .
the above basic information indicates that this is not a very mature project ( seemingly personal maintenance ) , but it does have a lot of Chinese people are interested .
I believe there are many students know why people on androidpn so interested , this is situation ah : Because Google official GCM ( previously called C2DM) can not be used in the country . In addition, domestic and before that a third party is not available handy push service . So, we had to do : their practice . Start from scratch ? Too much work , too uneconomical . So from the beginning of open source . And also happens to be open source project, specifically for the Android Push the afterlife , it androidpn it. mqtt There is no integrated so well you can quickly run up .
but androidpn build up, the situation? CSDN programmer on a beautiful article androidpn Push Probe is hot . Of this article raised a few questions:
androidpn server receives the message, how do you know which user you want to send ?
Once the server is restarted , the client does not seem to auto-reconnect , you need to interrupt the user's own back- Service and then restart the application .
androidpn server does not save the message . It is a message that will be sent out there , even if the client did not online , it does not re-issued.
authors like that , not just settle for the environment to build up, and thinking to do for your business needs . Resolve the issues raised under her :
The first question is relatively simple, go to customize the user system, the business part of the user system needs to correspond with androidpn .
The second problem is the small detail , androidpn client does not have to do these details.
The third problem is the most important. androidpn behind Openfire , is XMPP IM server , the message content is not going to fall , that is only stored in memory about offline messages . If you want to produce with the need to consider the transformation here .
follows from androidpn technical foundation to a depth analysis .
androidpn is an integrated solution , which is based on the XMPP open source components . Based on that server Openfire , client -based Smack, XMPP open source components which two are the most common of the two . androidpn using the Spring framework to do a Web tier , the XMPP IM components integrated together to achieve Android Push functionality. Therefore , androidpn availability from the following aspects:
its dependence on XMPP IM protocols and communication mechanisms , whether it is suitable for Android Push scene .
whether it is Android Push needs to do the necessary customization.
first aspect , XMPP protocols and open source components . XMPP is a mature IM ( instant messaging ) protocol, based on XML text ways, flexible and powerful . Most foreign countries are based on XMPP chat services , such as : Gtalk, Facebook Chat, iMessage , etc. Because of this , so some of the open source XMPP component availability is also good , the domestic many emerging chat tool is fully based on the XMPP beginning to develop open-source components , such as rice talk .
However, the author has realized a similar experience mobile chat App speaking , XMPP open source components have their problems, needs large-scale transformation :
XMPP protocol complex redundancy , the client cost flow , costs of electricity ;
open source XMPP server (androidpn chose Openfire) limited capacity of a single point , the cluster program complex , immature.
For these reasons, and taking into account a wide range of technically more uncontrollable transformation , where the team so I just started using XMPP open source program , and later completely cut to the realization of their own technical solutions on the.
The second aspect , Android Push demand scenarios , in addition to the message can be pushed to the client in a timely manner , what other basic needs it ? Here cite two examples : first, to ensure that the message can reach . Whether there is a mechanism to ensure that messages are not lost , for whatever reason . Second, to specify a group of people push messages . anroidpn based XMPP IM component is not considered these , you need to do a lot of custom transformation .
To sum up , the use of androidpn can simply do: push the message to the client . However, to make it suitable for developer needs, and run in a production environment , you may need to do a lot of custom development work . From the author communicate with multiple developers get feedback, up and running in a production environment where a lot of problems .
mentioned above , there is nothing available before the domestic third-party messaging handy push service , so we have to consider their own structures . Recent domestic third-party news push service opened , it is the aurora push, ordinary developers can always sign up , download the SDK to do integration , the whole process can be completed three minutes .

aurora it ? Seems pretty good , first try to say
------ Solution -------------------------------- ------------
to the force
ago I felt very good androidpn use , always receive push messages ------ Solution ------------------------------- -------------
tangle for this thing for a long time , has been found in the android good push solution

Haha seems androidpn really torture a lot of people

seems androidpn instability is known ah

expect better push service ah. . .

XMPP protocol that is a lot of problems ah

go to the official website to see, used to know the effect ah
------ Solution ---- ----------------------------------------
true, then if androidpn to solve more problems
------ Solution --------------------------------- -----------
androidpn not used , but listen to a lot of people say that the real problem with a lot of

to try first , steady push on the line as long as

who push up the source distribution for your reference ah ?
------ Solution ---------------------------------------- ----
good to say , with androidpn then need to improve on too much ------ Solution ----------------------------- ---------------
aurora push, tested, even if the message is not too accurate , sometimes delayed several minutes, the person who posted promote aurora have come CSDN , now we do your own push
------ Solution ------------------------------------ --------
easy to use on -line , first try ------ Solution --------------------------------- -----------
open source programs are actually still not perfect , there are some problems also normal
------ Solution ----------- ---------------------------------
really not easy to use , androidpn long time did not update it
------ Solution ------------------------------------------ -
can be grouped push right

Baidu cloud push . . can also be used
As for stability. . So-so to

recently used the aurora , the effect Yes, Baidu cloud push just on the line soon, still in the exploratory phase , testing to know.

androidpn do not do anything to meet the requirements for a long time , can only hope that an independent third party push the

now that several have developed to what extent ?

new to push this , it seems quite reasonable

good, but now there are many people using XMPP, laborious
