hi,

Actually, i have to develop an application which will serve like a mobile tracker.
I want to know some info:
1.is this possible to hide an application's installation after installing on mobile phone, so that user can start that application using some kind of code.
2.How can run my application in backgroud and continuously listening mode.Thanks in adavance.
Your help will be highly appreciated!

it sounds as a quite complex app to start out with j2me, just asking for code and expecting something to actually work (without knowing the language and/or platform) seems pretty unrealistic to me...
but good luck, maybe someone actually will do your work for you and write you the program...

anyways, here some info regarding your questions :
- hide an application installation : not as far as I know
- Background running needs a multitasking device, hence a S60... Also it wont contiuneasly listen as in it wont respond to keys...

Personally I think you might have more luck with the C++/Symbian combination...

Thanks for your answer.
Actually you get me wrong.I did develop a few project in j2me but didn't work on Location api before that's why i asked these questions.Any way i am searching,reading and exploring this api and related documents.
May be after studying i will be in good position to ask some questions about gps.
Tell me the general idea about gps in j2me.

Thanks for your help!
i have read these topics already but i just need some guidance from a master developer to start gps application.
Whats the general idea(logic) behind all this gps application.
1. how we access gps maps in j2me and how we edit them .
can some one just tell me the steps to develop a simple gps app. in j2me .

[Tiger79]

jsr-179 and j2me DON'T supply maps...
map providers do, so u will have to get maps from them... some have web services and stuff for that...
just take into account that in case you would like to create a piece of commercial software you will have to make some kind of deal with the map providers, they only issue test or demo accounts for their services but those cannot be used for commercial applications..
so j2me only supplies the means (through jsr179) to obtain a gps location, what you do with that location (maps or whatever) is up to you...

btw what do you mean with a simple gps app ?
a simple gps app would be something that reads out the gps coordinate, then petrib's links are good enough.. the moment you start retrieving and showing maps then its no simple gps app anymore, that is quite some work...
anyways in the wiki you have an example or otherwise check this discussion :

Thanks petrib,

i am working on a big project but at this level your help is enough for me.
I just want to get the coordinate and then email them to the server and sms them as well.
How can email them to my own email at start?

[Tiger79]
