Show alert as dialog with icon from the theme file in lcdui?

imgen — Wed, 22 May 2013 12:39:46 GMT

How can I show alert as a dialog and use icon from the theme resource? Maybe this should be separate question, but what I'd like is something like this

This image is taken right from the documentation of Alert, but unfortunately the doc doesn't say how to achieve this. I am quite unsatisfied with the doc though, too many things are left unsaid.

Manpreet_Singh — Wed, 22 May 2013 10:45:43 GMT

I am working for nokia s40 apps and the web service url link i m calling contain null attributes.
How to include null values as my program is not running whenever it encounters null values in xml file while parsing
like what changes i should do when fetching golden quote so that my program runs fine?

Code:

 public Vector parsingdata()

          {

                 

                  HttpConnection hc = (HttpConnection)Connector.open(url);

                                InputStream is = hc.openInputStream();

Uniqueness of midlet suite

TongMuan — Mon, 20 May 2013 15:46:32 GMT

Hi,

I'm preparing to publish an application with two different versions (Normal and Lite). Basically the only difference between them is the name of the application and content of data files included in the package - the two versions can even use the exact same midlet class.

I couldn't find any info about how phones uniquely identify midlet suites, eg. check whether a JAD/JAR being installed to the device is a new midlet suite or update to an existing one, so I tried on two devices (unsigned apps, installed via Nokia Suite, same MIDlet-Vendor in all tests):

Asha 310:
Installing same midlet suite with different JAD/JAR filename creates a new application on the device, no matter what the MIDlet-Name is. Reinstalling with same filename updates/reinstalls the existing suite.

Nokia 808 Pureview:
Midlet suites seem to be identified by MIDlet-Name specified in Manifest. Filename of the installed JAD/JAR is not taken into account.

Can this result be generalized to other Nokia devices too, meaning two JARs will be seen as different midlet suites on all devices if the MIDlet-Name AND JAD/JAR filenames are different (and same if both of those match)? Or can something else (midlet class name/package or signature?) affect the detection as well?

Also, for Nokia Publish / Nokia Store on S40, does this mean that as a publisher, when uploading a new version of an existing app, I have to always upload JAR file with the same filename as the previous version, to avoid duplicates being created on S40 devices if user updates/redownloads? For Symbian apps, I've been including version number in SIS file names, just to make it easy to check that I actually uploaded the correct version.

Designing for Asha/S40 Touch and Non-Touch

matteovega — Fri, 17 May 2013 16:00:31 GMT

Dear Community,

I am a graphic designer with intermediate development knowledge and I have a question about designing an application for Nokia Asha. I'm trying to design an app that works on both touch only and no-touch devices without creating too much additional work for the developers.

In terms of UI navigation, is there a simple way to support both non-touch and touch enabled devices? For now I have two separate UIs (See PDF attachment). One making use of the hardware softkeys and one with the pull up menu as used by LWUIT for Asha. Does the Asha LWUIT layout/UI work on non-touch device, if so, how? I have never designed for Nokia S40/Asha before so any help is greatly appreciated.

Kind Regards,
Matteo Cuellar

How to deal with object that is wider than screen?

pongsakorn — Fri, 17 May 2013 10:35:43 GMT

Say, I have a narrow bar object with width = 700 and height = 20. (Which is wider than the screen)

I want to be able to horizontal drag this bar so it display the rest of it.
I already register it to frameAnimator but when I call drag function. Its new X would be less than 0 which will cause an exception. (Imagine when you drag a bar to the left, its X would be decreased)

Please guide me or you can point me to places where I can read more about this.

I don't know if this is the right place to ask but I dont see a forum for gesture API.

Thank you :)

Hi,

I wonder which jar I should use for Asha 1.0 (Nokia 501)?

- S40-touch-and-type.jar
- S40-with-themes.jar

I use the first one and have NullPointerException trying to instance TextField.

Code:

        txtFrom = new TextField(5);

        txtFrom.setConstraint(TextField.DECIMAL);

        txtFrom.setText("1");

...

LWUIT TextField issue (Asha FullTouch )

bogus40 — Thu, 16 May 2013 08:15:41 GMT

Hi,

I use LWUIT plugin from Nokia\Devices\Nokia_Asha_SDK_1_0\plugins\lwuit\lib\sdk2.0\S40-full-touch.jar in my project.
All works OK despite touch on TextField. It doesn't open VirtualKeyboard after my touch. I have to tap TextField many times to open VK.
It works very random. It should open VK after first tap on TextField.

And one think more. After back from VK I see blinking cursor in my TextField.

My code snippet:

Code:

        txtFrom = new TextField(5);

        txtFrom.setConstraint(TextField.DECIMAL); // shows VB with numbers only

        txtFrom.setText("1"); // initial value

        ctnWest.addComponent(txtFrom);

        txtFrom.addActionListener(new ActionListener() {

            public void actionPerformed(ActionEvent evt) {

  ...

                evt.consume();

            }

        });

        txtFrom.addDataChangeListener(new DataChangedListener() {

            public void dataChanged(int type, int index) {

...

            }

        });

Have someone met some issue? I launch this app on Nokia Asha 311 and Nokia Asha 310.

Thanks for help.

LWUIT list lazy loading.

vishal.bharati — Tue, 14 May 2013 08:09:50 GMT

Hello Developers.

I am developing j2me app in which am loading lwuit list with common default image.
Once list is displayed with default image. i need to download the element specific image from the server.
And as images get download one by one i need my list to be refresh with new image.

i have tried following functions.

1) List.setSelectedItem(obj) // object having container with new image.
2) GenericListCellRenderer.getListCellRendererComponent(list1, (Object)createTempContainert(), 0, true);

Both of the above didn't worked.

Can anyone knows how to update particular element from the list.

All i need to replace the common image with the newly downloaded imaged from server.

Please share your ideas with code snippet if possible.

Thanks.
Vishal

How to get our border back in TextArea and TextField?

Nokia Asha Emulator Error

grift — Mon, 13 May 2013 20:07:24 GMT

When I run the new Nokia Asha Emulator, I get the following error.

Java SE Development (JDK) version 7 update 21 or later detected. Install JDK 7 Update 17 or earlier.

I have reverted back to version 7 update 11, but still get this error. Can anyone suggest a fix? Strange that the Nokia SDK 2.0 emulator worked fine with the latest version of Java, but the newer Asha SDK doesn't work :confused:

muhamad.iqbal — Mon, 13 May 2013 12:38:34 GMT

Hello guys,

I download lwuit source code and i put it on my project. I trace the Display.getInstance().getImplementation() in Image class, with System.out.println("lwuit implementation: "+Display.getInstance().getImplementation()); in method Image createImage(String path) and Image createImage(byte[], int, int). All of that produce error: NullPointerException on getImplementation(). there is no setImplementation in LWUITImplementation class. I want to fixed this bug with make setImplementation in LWUITImplementation. But, where do i call the setImplementaion in Image class...?. Or any other idea to fixed the bug...?

Best Regards,

The difference between "Connectivity" and "Network Access"

Weave — Mon, 13 May 2013 12:00:23 GMT

Hello everyone,

I'm new to midlet programming, I was just looking at the API access rights on Series 40 6th FP1 phones here.

According to the chart for these devices in the "Untrusted 3rd party domain" "Connectivity" can be set to "Always Allowed" but "Network Access" can not.

My question is what is categorised as "Connectivity" and what as "Network Access"?

Specifically I want to create a midlet that will connect to a web server and retrieve some JSON format data created from a PHP script, will I be able to set the permissions for doing that to "Always Allowed"?

Also, will the permissions chart I've linked to be applicable to the Asha 501 too?

Thanks.

how to implement menu pop up on list item long press in J2ME?

chandu_1233 — Mon, 13 May 2013 07:11:45 GMT

down vote favorite

I am developing an J2ME application where i have a list. Now i want to display a pop up screen with three menus(delete, details and cancel) when i will make a long press or click on any of the list item / row. I have seen similar type of features in some nokia touch phones(Check the whatsapp application).

I have tried with below code:

Code:

 m_lAccountsList.setCommandListener(this);

    m_lAccountsList.setSelectCommand(selection);



   public void commandAction(Command c, Displayable d) {

    if(c == selection)

    {

        // I need to implement the pop up menu

    }

Is this pop menu is possible for j2me? .How i can implement this?

local sql database storage

deanchalk — Fri, 10 May 2013 09:15:05 GMT

Hi

I am new to the Asha platform, and am excited by the new phones being release (501 etc). I am thinking of developing an app that will extensively use local custom data, which I'd like to query via an SQL or sql-like interface.

I have built windows 8 apps that use SQLite, and I want to know what the Nokia-recommended approach is for storing complex relational data locally

Thanks

Does the new Asha 501 support copy paste?

imgen — Thu, 09 May 2013 17:25:10 GMT

My app desperately needs this capability (and push notifications which new asha does support), so I am really concerned whether copy&paste will be supported? If not now, is it in the works?

Nokia Asha 501 - What It Means For Developers?

shai.i — Thu, 09 May 2013 07:37:36 GMT

Hey Everyone,

So Nokia just announced the Asha 501 with the redesigned Asha OS, i was wondering what is everyone take on the device, hardware, launch, price etc?

My 2cents is that the device is beautiful and has a great price (even less than the 311 i think), i did thought with all the pre-leaks that it will have a higher screen res (HVGA?) or at least to maintain the current Asha FT screen res (240x400) for maximun compatability.

PIM API ContactList::removeContact not removing contacts?

lordbritishix1982 — Mon, 06 May 2013 17:50:12 GMT

Hi experts,

I am struggling to understand why ContactList::removeContact always throws an exception with a description: "the item does not belong to the list" whenever I try to delete a contact that I have just created using Contact::createContact(..).

I create my contacts using the following snippet:

Code:

PIM pim = PIM.getInstance();

contacts = (ContactList) pim.openPIMList(PIM.CONTACT_LIST, PIM.READ_WRITE);                                        

Contact contact;

for (int x = 0; x < CONTACT_COUNT; ++x) {

        contact = contacts.createContact();

        if (contact != null) {

                String[] name = new String[contacts.stringArraySize(Contact.NAME)];

                name[Contact.NAME_GIVEN] =  FIRST_NAME[random.nextInt(FIRST_NAME.length)];

                name[Contact.NAME_FAMILY] =  LAST_NAME[random.nextInt(LAST_NAME.length)];

                contact.addStringArray(Contact.NAME, Contact.ATTR_NONE, name);

                contact.commit();

        }

}

contacts.close();

and I delete all contacts using:

Code:

....

ContactList contacts = (ContactList) pim.openPIMList(PIM.CONTACT_LIST, PIM.READ_WRITE);

PIMList list = pim.openPIMList(PIM.CONTACT_LIST, PIM.READ_WRITE);

Contact contact;

for (Enumeration e = list.items(); e.hasMoreElements();) {

        contact = (Contact) e.nextElement();                                                

        contacts.removeContact(contact);

}



list.close();

contacts.close();

...

However, if I delete a contact immediately after creating it:

Code:

contact = contacts.createContact();

if (contact != null) {

        String[] name = new String[contacts.stringArraySize(Contact.NAME)];

        name[Contact.NAME_GIVEN] =  FIRST_NAME[random.nextInt(FIRST_NAME.length)];

        name[Contact.NAME_FAMILY] =  LAST_NAME[random.nextInt(LAST_NAME.length)];

        contact.addStringArray(Contact.NAME, Contact.ATTR_NONE, name);

        contact.commit();

        contacts.removeContact(contact);

}

Then it deletes the contact successfully. This gets me to think that you need to pass the exact instance of the contact object that you have created in order to actually delete it. Can anybody confirm that this is the case? If so, then is there any other way to delete a contact without actually using the exact Contact instance?

Thank you in advance!

QOTW: launching the Nokia store client from a midlet

shai.i — Sun, 05 May 2013 16:50:46 GMT

So i'd like to contribute my nice question for you all (even though i know the answer i think its a nice question that will get you guys exploring & thinking & digging through the java library).

Can you launch the Nokia store client from a midlet?
The use case for such is to link back to your publisher page and/or to help the user rate your app etc.
a simple enough question you'd think but not a simple enough answer because the answer is not a determinant Yes or No.

When you think about the answer think of the platform you working with (big difference between Series 40 and Symbian) and there are also other difference within the same platform.

UDP broadcast not working (Asha 310)

da32x — Fri, 03 May 2013 06:25:04 GMT

Hello!

I'm trying to broadcast a UDP package (datagram) but can't get it to work on the device (Asha 310). Here is my code:

Code:

  UDPDatagramConnection conn = (UDPDatagramConnection) Connector.open("datagram://");

  System.out.println("Local address " + conn.getLocalAddress() + ":" + conn.getLocalPort());

                                

  Datagram dg = conn.newDatagram(pPacket.length);

  dg.setData(pPacket, 0, pPacket.length);

  dg.setAddress("datagram://192.168.0.255:1234");



  conn.send(dg);

If I use concrete address (e.g. 192.168.0.2) the packet is send without problems. If I use 255.255.255.255, conn.send() finishes without exception but nothing gets send on the network (checked with Wireshark). If the address is using the correct format to broadcast just in this network segment as above (192.168.0.255), conn.send() throws "Failed to send datagram" exception.

In the simulator 255.255.255.255 still does not work but 192.168.0.255 works just fine. However on the device nothing works (except sending to a concrete, non-broadcast address). Any clues? Is the UDP broadcast possible at all on Asha devices?

Thanks in advance.

Variable not changing

faysal515 — Thu, 02 May 2013 21:45:26 GMT

I have some StringItems buttons(with actionCommand for items) which all switch to the one same form.And the switched form showed the string which item(button) I clicked.If I go back to the previous frame through another StringItem(button) and click any different button, the switched form showed the old string I clicked.

Code:

else if (item == stringItem3) {

            if (command == aCommand) {

                // write pre-action user code here

                result="a";

                switchDisplayable(null, getResultForm());

                // write post-action user code here

               

            }

        } else if (item == stringItem4) {

            if (command == bCommand) {

                // write pre-action user code here

              result="b";

                switchDisplayable(null, getResultForm());

                // write post-action user code here

                 

            }

        } else if (item == stringItem5) {

            if (command == cCommand) {

                // write pre-action user code here

               result="c";

                switchDisplayable(null, getResultForm());

                // write post-action user code here

                

            }

        } else if (item == stringItem6) {

            if (command == dCommand) {

               result= "d";

                // write pre-action user code here

                switchDisplayable(null, getResultForm());

                // write post-action user code here

                

            }

        } else if (item == stringItem7) {

            if (command == eCommand) {

                // write pre-action user code here

               result="e";

                switchDisplayable(null, getResultForm());

                // write post-action user code here

                 

            }

so basically ,first time my result(global variable) changes,but after getting back to the previous form it won't take the value given here.
I think I explained my problem clearly.Waiting for reply.

DeviceControl Backlight

Matthias.Bay — Thu, 25 Apr 2013 19:41:29 GMT

Hi,

DeviceControl.setLights(0,100); works well, but how can you change the light back to the users default value (in the settings)?
I could not find a method like DeviceControl.getLight() or something like that.

Is there a good solution for the problem?

Media-rich JAR too large?

grift — Wed, 24 Apr 2013 09:08:10 GMT

I am currently developing a Java application that makes use of quite a lot of small graphics and sounds. Unfortunately, because of this, the size of my JAR exceeds the 2MB limit. I have already followed some of the steps to reduce the size of my images with this link. I have also been using the obfuscator, which has helped too. The problem that I have is that the bulk of the JAR is being taken up by my sound files. The sound files themselves are already at the lowest possible settings I can have them at without compromising the quality and I've already tried experimenting between some of the different formats MP3 and WAV with little difference to the JAR size.

Has anyone got any ideas on how to get around this issue?

Development environment clarification for S40 touch

strelamcqueen — Tue, 23 Apr 2013 11:08:52 GMT

Hi all,

I've done a couple of apps with Qt C++ for S60 and earned for a new PC with them ( ;-) ) and I'd like to move to S40 due to larger pool of users. There's great support on the Nokia developer site but despite many (too many?) instructions I got lost how to put together a simple app that would do a+b=c for the beginning.

My question is: I use SDK 2.0 and my target phones are S40 touch. What is the structure of files (which files, projects, etc.) that must be put together to make an app? Where (which file) is the code that does the function (e.g. a+b) located? I realize I may sound stupid but I better ask one time than be a fool forever. I don't know Java but I guess I can learn step by step.

Thanks. I am still one of those sticking with Nokia and avoid more fancy (expensive) devices and I'd like to stay here.

Add list after showing form (hack for lwuit s40 list bug)

xuanphung001 — Tue, 23 Apr 2013 07:21:38 GMT

Hi all,

I'm using Tourist Attractions source code at link https://projects.developer.nokia.com...istAttractions
Showing the main View(extend Form) AttractionView with function:

Code:

public void show(Guide guide) {

        this.guide = guide;

        attractionList.setGuide(guide);

        this.setTitle(guide.getCity());

        super.show(); //Form.show()



        // Add list after showing form (hack for lwuit s40 list bug)

        if (!this.contains(attractionList)) {

            addComponent(attractionList);

        }

        repaint();

    }

Note that the form showed before attractionList(lwuit.List) was added.
Above code work fine with nokia phone SDK but fail on other devices(not nokia phone, such as sun java wireless toolkit(WTK)).

When using WTK, i add Thread.sleep(100000) before repaint();

Code:

public void show(Guide guide) {

        this.guide = guide;

        attractionList.setGuide(guide);

        this.setTitle(guide.getCity());

        super.show(); //Form.show()



        // Add list after showing form (hack for lwuit s40 list bug)

        if (!this.contains(attractionList)) {

            addComponent(attractionList);

        }

        try {

                        Thread.sleep(100000);

                } catch (InterruptedException e) {

                        // TODO Auto-generated catch block

                        e.printStackTrace();

                }

        repaint();

    }

then it work fine in 100 seconds, i can increase this param but it is a bad ideal.

So how can i fix it with WTK?

Thanks & Best Regards
Phung
