Is there an event when the mobile connections are changed

Hi, expert,

I'm looking for an auditor check the following:

1. when the phone is connected to a mobile network not connected

2. when the phone is connected to another mobile network (another carrier or wifi) from current network

3. the current mobile network connection is dropped.

I found of initailly than ConnectionAttemptLIstener (http://www.blackberry.com/developers/docs/5.0.0api/net/rim/device/api/io/transport/ConnectionAttempt...). I thought I could use it to change mobile network connection. It turns out that I just couldn't. He listens to the event on ConnectionFactory which really is a connection on the connected mobile network.

Did some research and I could not find any related information.

So is it possible for me to achieve what I said at the outset?

You can use a combination of CoverageStatusListener and RadioStatusListener to have access to these events.

CoverageStatusListener will let you know what type of network access you have access from your coverage (by cell phone connectivity, etc.) WLAN network and which network transports are available).

RadioStatusListener will let you know when the changes on the cellular network occur as signal changes, changes the base station etc.

RadioInfo class can also be used to receive information on the current mobile network too.

Kind regards

  • Is there an event when the model color depth/pixel format is changed?

    Is there a way I can detect the change in depth of color in a composition?
    I know that I can react differently by calling PF_GetPixelFormat() on render for the format/bit depth of current, but I was wondering if there is a way to detect and react to the event when a user changes the number of colors in the publication manual?
    Basically, what I want to do is hide/change settings in the ECW according to the bit depth.

    Any help appreciated :-)

    You can use PF_UpdateParamUI during the call to render to force AE to refresh the user interface.

    You can also hide/show params at any time using AEGP_SetDynamicStreamFlag and AEGP_DynStreamFlag_HIDDEN.

    I saw blackberry webworks API

    public static Boolean blackberry.system.isMassStorageActive)

    who says if massstorage is active or not.

    But I can't keep on request this API every time. I'm looking for an API that gives me the reminder.

    Can you please help.

    On the side of Java, this can be done by implementing a FileSystemListener and the rootChanged method:

    public void rootChanged(final int state, String rootName) {
        if (rootName.equalsIgnoreCase("sdcard/")) {
            if (state == FileSystemListener.ROOT_ADDED) {
                /* SD Card is available. */
            } else if (state == FileSystemListener.ROOT_REMOVED) {
                /* SD Card is not available. */
            }
        }
    }
    

    I was not able to find a corresponding WebWorks API or API community well, so I think you need to create your own custom extension to implement this feature of the listener.

  • Intercept touch green application event when the device is locked

    Hi, I'm new to blackberry. What I want is I want to take a key event (green or red button) when the device is locked and do specific tasks in my application that runs in the background if this button is pressed. Is this possible? How can I do?

    Just to be 100% accurate, it is possible for a keyListener (look to the top of the class) to pick up some events even when running in the background.  It can be different events when the device is locked.  Indeed, the events may be different depending on whether the "locked" screen is currently displayed or not. And the entire lot is dependent on operating system level, in other words, the same device running two different levels of OS will possess differently in terms of what keys can detect a listener in the background.

    So if you have a BONE and a specific device, so it might be something you can do, especially if it is an older operating system.  However if you try to create something that works generically, then know that I've tried and failed!.

  • display the text in the navigation bar when the user connects

    Hi all

    I'm (still ) on Apex 4.2.6.

    Currently, I have in my page templates, the following code snippet:

          <div class="logoBar">

              <img src="#IMAGE_PREFIX#themes/theme_125/images/logo_.png" />

              <h1><a href="#HOME_LINK#" id="uLogo">#LOGO#</a></h1>

            <div class="userBlock">

              <span>Username: &APP_USER.</span>

              #NAVIGATION_BAR#

            </div>

          </div>

    I have an obligation to display the user name (APP_USER) and of the company the user works for point Application AI_COMPANY, only when the user is connected. When the user is not connected; instead of these elements, I must show a connection link. Well, I know how to display a link to the login page, only when the user is not authenticated, using the navigation bar. Currently, when a user is not authenticated; the page shows: username: person. It's because he's in my page template. How can I show only the user name when the user connects? And then only display the name of the company?

    My first thought was to add an item in the navigation bar. But these elements comes in the form of links. Is it possible to add a navigation bar element and let it display as text? Of course, I could write a dynamic action on page 0 to remove the link, but I'm looking for a nicer sollution or better.

    I have apreciate your help!

    I take it, you use the same model of your home page and login page.

    You could use 2 different models or get out your elements in your model and put them in page 0.

    You can then make them conditional based on the number of page

Your application has problems running when daylight saving time to save changes?

  • Portege M500 cannot start when the USB ports are loaded

    We have a M500 that recently seems to be affected by start-up problems when the USB ports are loaded with things like KB and Wireless Mouse USB external adapter.

    When these ports are occupied at the start, all the usual tools seem do not load and the associated icons do not appear in the toolbar at the bottom of the screen. The machine in question XP Professional and has 2 GB of RAM. The machine software is generally updated. Machine seems to start normally when the USB ports are empty.

    Once completed a successful boot USB ports can be occupied and the machine will then seem to operate normally.

    Any thoughts?

    Thank you.

  • HP Color Laserjet M277n MFP: How to use the black cartridges only when the color toners are empty

    Hello team HP,

    I recently bought a HP Color Laserjet MFP M277n I printer I print black & white user only and really don't need color prints. How to set the printer options to print only black & white? How can I replace only the black cartridge when the color cartridges are empty? How many prints (approximate), we can take by toner?

    Kind regards

    Christèle

    Hi @Pavumba,

    Welcome to the Forums of HP Support!

    I understand you're wondering how to use black ink only on your HP Color Laserjet M277n MFP printer. I would be glad to help and don't forget to come back to this thread and check "Accept as Solution", if I have successfully helped solve you the problem. If you want to say 'Thank you' to my effort to help, click on the "thumbs up" to give me a Kudos.

    I see that you wonder if you need to replace the color cartridge when it is low. This printer is a printer AIO, therefore, you need to replace the ink cartridge when it becomes too weak to be able to resume printing. However, if you print mostly in black, you can configure a preset black only to print in black and white. This would help reduce the use of the color cartridges.

    NOTE: Composite black - for black and white images and photos, a mix of colors called 'composite black' can be used to achieve the quality significantly improved picture and soft gray tones that can be achieved with only black toner. For users who want to print images using just black toner, many HP printers color customer offer configurable options allowing the client to print using only black toner. For example, by selecting "print in grayscale" in the printer driver Specifies print using black ink only. For more information about the use of the toner cartridges, please see this article: how the Toner is used.
