Problem in creating image in nokia s40

[marzieh_312]

hi everybody,

I used this line of code to create an image:

offScreenImage = Image.createImage(getWidth(), 20 * bitmapFont.getHeight());

I ran this code in 6270. But when application reachs this line it throws OutOfMemory error.
This occurs only on s40 phones.
It is OK on Nokia s60, SE and emulator.

Can anybody help how I can fix this problem?

thanks in advance!

What are the height and width?

[marzieh_312]

its around :

width: 217
height: 380

Well... it throws an OutOfMemoryError because you don't have enough memory. In this case, you probably need around 320k free to create the image.

You need to use less memory.

Cheers,

There's no magic. You just have to keep fewer images in memory. Discard any images you don't need. Avoid creating large double-buffer images like you are doing here.

My other top-tip: when you write a game or application for mobile devices, start with a the lowest specification device you want to support. Then you won't have nasty surprises like this one.

Cheers,
Graham.
