Although you have not mentioned the device you are using, generally speaking your 3rd image (pawan kalyan cgtr Dialogues(2).jpg) is just huge, 168 kilobytes for download and 700 kilobytes to view. Considering that even the smaller images are around 90 kilobytes when uncompressed, you can easily run out of heap on a device with a 1-2 megabytes restriction.

Hi Wizard,
thanks for reply,i have tested with Nokia SDK 1.1 and SDK 3.0.5 Device Manager,but actually if i remove HtmlComponent Class from my displaycompleteNewsScreen() method,then i am able to display all my list details succeefully....
but when i run my application initially list will be loaded, that time there is no question of executing displaycompleteNewsScreen() method ,This method will get execute only if i click on any list item?but if i place HTMLComponent class then i am facing Outofmemory Exception?can you give your suggestion?

Try to test it on some real target device or check the max memory settings on the SDK you are using for testing.
