Does anyone know if there is a J2ME developer guide for Samsung phones, specifically the A900?

If anyone has developed for this device and has info on icon sizes (for outside the app when launching) or icon sizes that work well for use with the Menu class, please let me know.

Thanks,
Greg

I'm working on a MIDlet that requires reading in static data from a file. The file has about 1000 lines with roughly 100 characters on each giving me a file size of around 80KB. I was hoping to keep this file size as small as possible without having to reduce the amount of data in it. Does anyone have any tips/tricks for making this happen?


Thanks!

As far as I know, Nextel is the only US carrier that one can use the J2ME location API with. This requires a GPS enabled iDEN handset. Does anyone know if Cingular, AT&T, SprintPCS or Verizon currently support this API or offer similar functionality to developers?

Yuri -- Thanks for those links.

Do you know if the carriers listed (i.e. Cingular and AT&T) currently support Ericsson's MPS or only have announced that they intend to support this? If I developed an application with MPS, could I deploy it today and have access to a handset's position data? Have you successfully tested your MPS application with any US carriers?

Thanks again,
Greg

I was curious if anyone has an updates on this topic. Aside from Nextel's GPS services, are any other carriers actively working with developers to bring to market LBS based applications?

Prior posts mentioned that bigger companies can make use of a carrier's LBS data if an agreement is in place. Does anyone have any examples of this (i.e. a third party company working with a carrier to utilize their customer's location info)?

GamesSMS actually looks pretty interesting for international SMS. Has anyone used this? Do you know if there is a list of countries or carriers that are supported by GamesSMS?

I do have access but I haven't been able to come up with any additional information. Unfortunately, the message boards on their dev portal don't see too much action.

Does anyone know of any restrictions around sending SMS messages using WMA with Nextel's iDEN network?

Motorola's 'iDEN Developer Guide' states "the WMA API is intended for sending SMS within the Nextel network only due to the iDEN's Caveat for WMA over Datagram" (from pg. 297 of the MIDP 2.0 Dev Guide).

Does anyone know exactly what this means? Can you not send an SMS to a Cingular customer or non-Nextel number using WMA?

Thanks,

Does anyone know what code to use (MIDP 1.0 preferably) to check for internet connectivity on a Nokia or Sony Ericsson phone before trying make an HTTP connection?

When I use the following code, an exception is never thrown when I have my handset's internet connection turned off:

Can someone confirm that the RecordStore getSizeAvailable() method returns a value in "bytes"? The books and online articles I've seen say that this method returns bytes, however, our testing is showing that it is actually returning KB.

Does anyone know how I could package a license.txt file in a MIDlet? I'm building/packaging the MIDlet using Sun's Wireless Toolkit. Is there a specific folder the file should be in to be part of the jar?

Thanks!

We do make use of an HttpConnection in our application...not sure exactly what you mean by "requires permission" though. Is the only difference between packaging as MIDP 2.0 vs. 1.0 the following JAD parameters:

MicroEdition-Configuration: CLDC-x.0
MicroEdition-Profile: MIDP-x.0
