Hi,
Please I need help in finding a source code for designing a map on mobile application, I intend using a scanned image for the map.

Hi Francesco,

sorry for the delay of my answer, but I totally missed your reply… :-/

Anyway, do you have this problem on emulators, or on real devices?

Hi Pit,
thanks for your fast answer. I tried to change the format for the static map to png16 (I was using png32) and it works

Now I have a problem with displaying the image: I can see just the first few pixels while the rest of the screen is black (width is alright, while the problem is with the height)

My code is pretty simple:

Image map = gMap.retrieveStaticImage(320, 240, lanLng[0], lanLng[1], 15, “png16″);
Form f = new Form(”Image”);
f.append(map);
display.setCurrent(f);

It is my first approach to midlets and I don’t really know what’s wrong. I also trying using canvas but I get the same result. Do you have any suggestion?

thanks again,
francesco

Hi Francesco,

this has probably something to do with illegal/corrupt data coming from server. If you try getting the map URL directly in your browser, does it work?

Also, which format are you using for your static maps?

Hi!
I’m trying to execute the code you posted on the Forum Nokia Wiki. I use the Sun Wireless Toolkit and the EsclipseME IDE.
I get the following exception when invoking the retrieveStaticImage method:

java.lang.IllegalArgumentException:
at javax.microedition.lcdui.ImmutableImage.(+11)
at javax.microedition.lcdui.Image.createImage(+40)
at GoogleMaps.retrieveStaticImage(+28)
…

could you help me?

thanks a lot,
francesco
