Problem with canvas and Image Create, j2me

[nixinumbra]

Hello everybody, I'm begginer in this forum and I'm programming an aplication.
I have problems with images, I'm trying to show an image "PNG", 90.4Kb, with a resolution 1600x1000.

private Image imagen=null;

public Image getImagen(){
if(imagen==null){
try {
mapa = Image.createImage("imagen.png");

} catch (IOException ex) {
System.out.println("Error");
}}

return imagen;
}

protected void paint(Graphics g) {
g.drawImage(getImagen(), 0, 0, 0);
}

it works in nokia 5530, but doesn't work in nokia x2-00, and when I change the image's size to a resolution of 400x250, it works in both. What is happenning?, what can I do?

Hi nixinumbra and welcome to the Nokia Developer Discussion Boards!

The reason why it's not working is that you are running out of memory on x2-00. The heap size on x2-00 is 2mb and on 5530 it is unlimited. Your 1600x1000 resolution image takes at least 1600*1000*2 = 3,2mb of memory depending on the color depth of the device. You can catch the error with OutOfMemoryError exception.

Lots of thanks. Do you know how can I know the celphones' heap size, or how can i know how much memory uses my application?

You can find the maximum Java heap size for a device from the below link. Choose a phone and open the Memory Functions tab.

And here's couple of wiki articles on how to get the free an total memory in Java ME.
