[pavanragi]

Hiii

i want to display an image and Description from Rss File on LWUIT Form Screen here my Code:

HTMLComponent com=new HTMLComponent();
com.setBodyText(detailNews.getDescription());
form2.addComponent(com);

In place of detailNews.getDescription(),the string coming form an Rss URL in a loop is

<p><img border="1" align="left" width="150" vspace="2" hspace="2" height="159" src="/tmdbuserfiles/Prithvi2_launch1(3).jpg" alt="Prithvi II, ballistic missile, DRDO, armed forces,Chandipur, Balasore district, Odisha State" />The Strategic Forces
Command of the armed forces successfully flight-tested the surface-to-surface Prithvi II missile from Chandipur in Balasore </P>

if i execute, i am facing the application has unexpectedly quit because ,it ran out of memory exception

Hi Pavanragi,

S40 Java ME has the restriction of Maximum heap Size 2-4 MB (depends on the device), and image and description from RSS file might easily cross above limit. I strongly suspect that image size is too big(more than 2 MB) or enough to through out of memory while loading.

Also note that HTMLComponent of LWUIT is not yet optimized for S40, it might available in the future.

Hi pavanragi,

I used following code and works fine without out of memory exception.

Display.init(this);
Form f = new Form("Hello, LWUIT!");
String html="<p><img border=\"1\" align=\"left\" width=\"150\" vspace=\"2\" hspace=\"2\" height=\"159\" src=\"/tmdbuserfiles/Prithvi2_launch1(3).jpg\" alt=\"Prithvi II, ballistic missile, DRDO, armed forces,Chandipur, Balasore district, Odisha State\" />The Strategic Forces Command of the armed forces successfully flight-tested the surface-to-surface Prithvi II missile from Chandipur in Balasore </P>";
HTMLComponent com=new HTMLComponent();
com.setBodyText(html);
com.setShowImages(false);
f.addComponent(com);
f.show();

I tested above code in S40 SDK 2.0 beta with LWUIT (S40-with-themes.jar) downloaded from here https://projects.developer.nokia.com..._for_Series_40.

Please check that you might have created too many objects and left without set to null after it is used.

Also close network objects after using it so that memory will be released and you won’t get out of memory exception.
