Default Quick questions about BB API possibilities for Student Project

Please Login to Remove!

Hello All,

I am currently a university student looking for a platform for a project I am working on, I have done a little research and BlackBerry might be my all-in-one solution. I have looked through the forums and RIM website, and was hoping you guys could quickly verify some API possibilities

I currently have a Blackberry 8310 with the 4.2.2 codeline

I was hoping you could let me know which of the following functions would be possible, a simple yes/no would be fine. Here is what I need my app to perform:

1) Acquire GPS Co-ordinates, send these coordinates via SMS (every ~1minute)

2) Acquire Altitude information, save this information (every ~1minute)

3) Take picture using the built in camera, save the image (either to device Memory or SD card), (do this every ~5 minutes)

4) Take picture, send via MMS message (about every ~10 minutes)

I was hoping this could be done solely on the blackberry so I do not have to use multiple platforms and interface in-between each.

Also, if you can guess what this project is, you win a cookie.

Thanks for all your help,
Best Regards
Moe

The GPS stuff is possible ... but controlling the camera, I'm not sure, I shouldn't think so.

Altitude? Don't think the device supports that.

pretty sure it's all possible to be honest. camera can be used using mmapi, gps does have altitude i think, sending a pic with mms should be possible too but i've never tried it.

you going to send a device up on a weather balloon?

Thanks guys, yeah I plan on sending it up. GSM only works to an alt. of about 600-2000m, but i think i can probably break about 25,000 and get some picutres of the stratosphere.

I looked through the RIM knowledge base, and the GPS stuff should be all good. If anyone knows the maximum altitude that the GPS API will handle, it would be great.

Can anyone confrim if a picture can be taken through the mmapi? From what i see in "JDE v4.2.1 API JavaDocs", there is no control over this function

Thanks

You are quite right taking picture with the help of mmapi in Blackberry is not supported in 4.2.1 im sure about that .. But im not sure about the latest versions.

you can't acquire pictures with MMAPI (maybe it will be added in 4.3), but you can invoke native camera application, allow user to make a picture and catch it programmatically using FileSystemListener.
