Hello all... i am new to Blackberry development...
My requirement is to display html content in a screen. my target os is 4.5
i found 3 ways
1:- BrowserSession - its working fine but that blackberry logo is a probelm . is there any effective way to remove or hide that?
2:- BrowserContent - got this from BrowserFieldDemo sample. its workign ok for simple pages but not properly for complex pages with style sheets, post requests etc.
3:- BrowserField - it has been interduced in 5.0. is there anyway to port it in 4.5 like any patch etc.

Please guide me

hi Baskar,

may i know why r u pushing 'indexScreen' after showBrowser();
and i think bSession.showBrowser(); is also not required...

try the following sample code

public class BrowserDemo extends UiApplication
{
    public static void main(String[] args)
    {
        BrowserDemo d = new BrowserDemo();
        d.enterEventDispatcher();
    }

    public BrowserDemo()
    {
        pushScreen(new BrowserScreen());
    }

}

class BrowserScreen extends MainScreen
{
    public BrowserScreen()
    {
        LabelField title = new LabelField("demonstrating browser");
        setTitle(title);

        BrowserSession visit = Browser.getDefaultSession();
        visit.displayPage("http www google com");
        visit.showBrowser();
    }
}

Hi,

ok, this is working fine.
but you directly push to browserscreen. i am using one edit box and ok button in index screen, when ever user enter any url and then click ok button means display browser screen using pushscreen. now i am come back index screen using back button display blank screen.

Thanks,
Baskar.

hi,

You know what my problem?
Thanks for your quick responses.

Thanks,

[Ashis]

sorry i am not properly getting your problem.

anyway what i hv understood from ur above posts, if ur 'indexScreen' contains an edit box and a button and u want to show the page entered in the editbox then you should push the 'indexScreen' first then call the BrowserScreen's displayPage() in the eventlistener of the button...

hi,

Correct, Once i am receving web page, how to come back to index screen(using back button or any).
Please give me suggestion.

Thanks,
Baskar

[Ashis]

Ok.if that is the requirement then push indexScreen first. then in the button click event call the browser session.
so when u will clik the button the browser will be shown. and if u will click the back button it will go back to the previous screen i.e. ur indexScreen.

[baskar]

hi Ashis,

- yes.
- i am calling previous screen every time, display blank screen.
- Please help.

Thanks,
Baskar

[Ashis]

i think there is no need to call the previous screen explicitely... and may be that is the reason for ur blank screen!
if u can post the full code of the class that u r using to display the browsersession, then it may help to identify the actual reason of ur problem.

hi,

sorry for late reply,
i attached my code please check it out.

public class indexscreen extends MainScreen
{
private VerticalFieldManager vManager;
private BasicEditField userurl;
private ButtonField connectButton;

private WebpageView webpageView = null;

public indexscreen()
{
super(NO_VERTICAL_SCROLL |FIELD_VCENTER );
initialize();
}//End of constructor

private void initialize()
{
try
{
userurl = new BasicEditField("","",Integer.MAX_VALUE,BasicEditFi eld.USE_ALL_WIDTH);

connectButton = new ButtonField("ok", FIELD_HCENTER);
connectButton.setChangeListener(listen);

vManager = new VerticalFieldManager(VerticalFieldManager.USE_ALL_ HEIGHT|VerticalFieldManager.USE_ALL_WIDTH|Horizont alFieldManager.USE_ALL_HEIGHT|HorizontalFieldManag er.USE_ALL_WIDTH|HorizontalFieldManager.FIELD_HCEN TER|HorizontalFieldManager.FIELD_VCENTER);
vManager.add(userurl);
vManager.add(connectButton);
add(vManager);

}//try
catch(Exception qwe)
{
qwe.printStackTrace();
}
}//fn initialize

FieldChangeListener listen = new FieldChangeListener()
{
public void fieldChanged(Field field, int context)
{
if (field == connectButton)
{
webpageView = new WebpageView(userurl.getText());
UiApplication.getUiApplication().pushScreen(webpag eView);
}
}
};//btn action
}

//class webpage
public class WebpageView extends MainScreen
{
public WebpageView(String url)
{
try
{
BrowserSession bSession = Browser.getDefaultSession();
bSession.displayPage( url );
bSession.showBrowser();
}
catch (Exception e)
{
System.out.println("Exceptrion rendering Error "+e.getMessage());
}
}

}

Thanks,
Baskar

i think i got ur problem...
there is no need to create another screen for the browsersession...

call the browser screen from the button click event like

if (field == connectButton)
{
BrowserSession bSession = Browser.getDefaultSession();
bSession.displayPage(userurl.getText());
}

you are pushing the WebpageView screen above indexscreen and then u are calling the browsersession which is another screen which is being pushed over the WebpageView. so after u r closing the browsersession the WebpageView is shown to you which is blank coz u hv not added any field to it!
