[elisafina1205]

Hello...
may i ask something?
i want to open image using app...
i use code from wiki sample code: http://www.developer.nokia.com/Commu...ery_in_Java_ME

when i try to open image with little size, its work just fine..
but when i try to open image from gallery (image that user take using camera) it keep giving me OutOfMemoryException.. how can I fix this? because one of my app feature is to open image from gallery..
note: i try using C2 device, which has 2mpx camera..

Hi elisafina,

The error indicates that you ran out of memory. The series 40 phones have very limited resources. The heap memory available for Java is 2 MB. You can find more information regarding hardware characteristics here:

A few considerations when displaying images on Series 40, is that you don't really need a high resolution image, because the screen is much smaller than the high-end devices. If for example you are capturing an image with the device's Camera, on C2-01, setting the capture quality to the lowest i.e. 0.1MP (240x320), creates an image that can be opened successfully without consuming all the phone's memory. Since the device's screen resolution is the same (240x320), you don't loose in displaying quality.

so, is this really impossible if i want to open an image that is saved in user gallery? because i think, we don't know user using 2mpx camera quality or 0.1mpx and we can't force user to take picture using 0.1mpx quality, isn't it?

Thanks

Try to get filesize in long variable instead of using integer

describes in detail why even a small image that is resident in the heap can thrown an out of memory exception.
