running best path algorithm on mobile devices

[MichaelGerzon]

Hello,
I would like to develop a software with the following features:
1. I have a mobile device and an ArcGIS server.
2. Data can be uploaded in advance from the main server to the mobile device.
3. Then I need to find the best path from one point on a road map to another on the mobile device while it is DISCONNECTED from the main server.

We need the device to be disconnected, because when you go to fieldwork there is obviously no connection to the server.

It is possible to create a map of road nodes in Network Analyst and then upload it to the mobile device. However, I can't figure out how to run the best path analysis on the mobile device without connecting to the main server.

Another option to calculate the best path is to use the ArcLogistics Navigator on the mobile device. However, I can't figure out how to use/set_up the navigator without all the ArcLogistics staff that comes with it. I don't need the logistics. I need only the best path calculation. I can't figure out if it is possible to buy a license for just the navigator without the ArcLogistics. I guess it was not built to work separately.

I find it strange that ESRI never dealt with the problem of best path on mobile devices that are disconnected from the server.
Can anyone help?

Thanks,
Michael.

I know you wrote this a few months ago, but I just came across it and thought I could provide some help.  The best way to deal with disconnected editing is to use a PDA device with windows mobile...not windows phone, android, ios, etc.  Not sure what you are using, but at this time ESRI does not support disconnected editing in anything else but windows mobile.  It is a shame, as microsoft is doing away with windows mobile, so that leaves us all in a position where we will have to update our program later.  But anyway...use windows mobile and do a search for code to find the best route.  I wrote a program a few years back, so I know that there is code in the codebase to do this.  You may have to search the archived code to find what you are looking for, then update it for arcgis 10.
