[android-developers] Re: Implementing 'push technology' into Android apps
hi miguel paraz, So now i feel what i have analysed is correct on the push service.I want to know how to implement the server, does the server has to intiate some javascript method. Also whether the android can implement the cometd using the jetty library these are my doubts, assume i have contacts in server and i want to update it in my android client whenever there is a new contact added, do you think using the Jetty Bayeux will be sufficient. If you have implemented and could be shared , it will be great Thank you On Oct 27, 2:13 am, Miguel Paraz mpa...@gmail.com wrote: On Oct 27, 6:01 am, arvchak arvc...@gmail.com wrote: Wat if we use Comet, even i have searching for this stuff not lucky though.Comet is the push technology implemented as an alternative to ajax.The gtalk we see in the gmail uses comet.I suppose we should implement this to make it easier.

[android-developers] Re: Implementing 'push technology' into Android apps
Hi - have a look at Diffusion - http://www.pushtechnology.com - I used this to push/stream data to a blackberry app and a website simultaneously. It has a nice feature called 'best message delivery' which ensures you can’t flood a device with the content you push to it (i.e. use to much battery power/lock it) – we were streaming foreign exchange rates which change about 8 times a second…, without causing either devices any problems). It has an open protocol so it should be possible to connect and receive data from any device/application that can open a socket. I think there is an Android library already packaged with it so you shouldn’t have to write your own library to get your self up and running, although the protocol is fairly straight forward if there isn’t one.

[android-developers] Re: Implementing 'push technology' into Android apps
There are lots of issues with implementing push technology, here are just a few: You are looking at the application layer, you need to be concerned about the transport layer(s). How does your server know the address (IP or other) of the phone? It gets assigned by DHCP and whenever the connection is broken/dropped for any reason it can be given a different IP address by the telecommunications provider. If you are connecting from the phone to the server to when the phone's IP address changes you may as well keep the channel open and pull the data down. With a WiFi connection the phone is probably on the inside of a NAT router so again making an incoming connection to the phone is not going to work. So many problems, you are probably best just sending an SMS message containing a url to your web server and getting the end-user to click on it. -- RichardC On Oct 16, 3:43 pm, rubeN_vl rvanluch...@hotmail.com wrote: Hi, What are the different ways to implement push technology into your Android app?
