Add SystemListener in any application related to the foreground?

Can we add SystemListener as soon as any application, in blackberry, comes to foregound? I mean, how can I check when ANY application comes to the foreground and SystemListener add?

Thanks in advance.

You cannot add a listener for another application.

You might be able to consider applications "active" and figure that it has the focus. You can also detect when it starts or stops using the ApplicationManager.getVisibleApplications

  • How add us shortcuts of applications downloaded from the app Store? (RT surface)

    Original title: App shortcuts

    Hello

    How add us shortcuts of applications downloaded from the app Store? (RT surface)

    For example: Skype shortcut on desktop

    Hello k0mrade,

    You can create shortcuts on the desktop for versions of the apps Web page, but not applications, in the strict sense. The version of the app Web page often has more features and options.

    The example you give is a good thing. If you go to the Skype Web page, you can do this Web page a favorite in user IE10 or IE10 Desktop interface. It also works with SkyDrive, Hotmail, Outlook.com, or any Microsoft service available on the internet.

    Once the favorite is created, open the Desktop IE10, then open Favorites and drag the symbol from the Web page Favorites and on the desktop. It becomes a shortcut on the desktop to this Web site (but will most likely open on the side of the user interface).

    In addition, if you use the same Microsoft account to connect to Windows RT, that you will use to connect to the Microsoft Web pages, when you open the shortcut that you'll already be connected.

  • Check if the application is in the foreground

    Hello everyone. My application runs in the background and has a GPS receiver and phonelistener. I created an eventinjector to ignore calls entrants (supposed to ignore calls only when the application is in the foreground), but it also ignores the call when the application is in the background. I tried

    {if (this.isDisplayed ())}
    Code number
    } else {}
    Do nothing
    }

    But this isn't working, the application continues to ignore all incoming calls, even when he is in the background.

    Hello

    This morning, I wad able to download podcasts on Wi - Fi using an application called PodTrapper. Since his return from work and Wi - Fi connection, I can't use any application to access the internet. Twitter, Podtrapper, BlackBerry App World, Evernote, DropBox, all indicate, I can't connect to the internet. However, the browser works very well and I'm typing this message forum about this.

    When I turn on Wi - Fi, I turn off my cell radio, but I enable data and also roaming Services. I don't have a data plan. I did not go to software update on my phone today (I have experience on my Torch 9860)

    Would be great if someone could point me in the right direction to solve this problem.

    He did not work at first, then I started to do a battery pull and it seems to work. I can download podcasts via PodTrapper and connection via Evernote.

  • Records related to the network

    No one knows what would be the best newspaper to investigate if a virtual machine has lost (intermittently) connectivity to the network? Someone is pointing out a problem that I'm fairly certain that's not my problem (relative to vm, a standard switch, host, etc.), but I would still do my part before I transmit to the network team. Thank you.

    Note the exact time of the question when noticed. Secret time frame in universal time, because on ESXi saves its logs in the UTC time zone. After the converted in time UTC, check the following logs for any question related to the network connected at this time.

    1 hostd.log - of the ESXi host

    2 vmware.log - the VM problem

    3 vmkernel.log - of the same host ESXi

    If you don't see anything relevant to networking... you can conclude this isn't VMware network related issue.
