Application does not and the condition to satisfy.

I have code for this method. Its not not run even a single line run here method. Please explain why its kind.

public static synchronized void pushGlobalLockScreen() {}
UiApplication.getUiApplication () .invokeLater (new Runnable() {}

public void run() {}
GlobalVars.currentLockScreen = new LockScreen();
GlobalVars.currentLockScreen = new LockScreen();
GlobalVars.lockStatus = GlobalVars.STATUS_LOCKED;
try {}
LocalStorage.setSmartFuzzLock (true);
} catch (MySystemException e) {}
MySystemException.addLog (e.getError ());
}
UiApplication.getUiApplication () .pushGlobalScreen (GlobalVars.currentLockScreen, 1, UiEngine.GLOBAL_MODAL);
UiApplication.getUiApplication () .requestForeground ();
UiApplication.getUiApplication () .pushScreen (GlobalVars.currentLockScreen);

}
});
}

If you have used the debugger and strengthened through this code and it's actually executing the invokeLater, then the reason is that the code runs this is running on the event Thread and does not give up it.  You code probably some 'wait' rather than relinquish control.  Step through the code that runs after it and see what happens - I think it is this code that causes the problem, not the code that you have demonstrated.

If you have debugged not this code, then please do.

That said, there are some things that you might consider encoding differently in the code provided:

public static synchronized void pushGlobalLockScreen() {}

-Why sync?

GlobalVars.currentLockScreen = new LockScreen();
GlobalVars.lockStatus = GlobalVars.STATUS_LOCKED;
try {}
LocalStorage.setSmartFuzzLock (true);
} catch (MySystemException e) {}
MySystemException.addLog (e.getError ());
}

This code probably didn't run on the event Thread.  I consider running before you start the code that must be on the thread of events.

UiApplication.getUiApplication () .pushGlobalScreen (GlobalVars.currentLockScreen, 1, UiEngine.GLOBAL_MODAL);

I could be wrong, but from memory, this code cannot run on the event either Thread.  And it does not block, then you code must run past it very well.

Be aware that will push a screen that runs across all screens (other than all the other global screens).  This global screen is not really part of your application.

  • The Inbox in the mail application does not all the messages that I can see through the Web browser

    I have a similar problem with the Mail application on Surface 2. Inbox does not all the messages that I can see through the Web browser. I chose E-mail download of any time in the account settings. But when it sync randomly takes messages in the Inbox to display. I uninstalled the app, restarted the Surface and again installed in the Windows store. But the problem remains. It's frustrating. I think the app is not fully developed.

    His works now. I did the sync and other things with no results. Then I noticed that my missing messages are somehow appearing in the file of the Newsletter. Then, I moved all the messages in the Newsletter folder in Inbox and unchecked it parameters. It's working now. There are apparently some bugs in the software that allows for the Newsletter to divert messages. In any case thanks for checking.

    Even if I'm not listening to music and I closed the app, why he has begun to show that if it plays on my lock screen, this also happens intermittently and not all the time.  Also, I noticed on my lock screen when music does not appear I have the music symbol in the lower left corner of the screen and the camera symbol at the bottom right shows that I never noticed before, normally only the symbol of the camera?

  • Script errors often slow Firefox, does not and the display no longer responds.

    In recent weeks, firefox has often been insensitive, usually represented as "does not. It lasts anywhere from a few seconds to several minutes (maybe more, but by this amount of time, I lose patience and "end task" in the Task Manager.) It is usually followed by an error "the script is not responding. What script it's varies. I answered by clicking on "stop script" which usually fixes the problem temporarily.

    The problem seems to occur more often at random, but happen always predictable on site with videos like youtube. Here, it's also worse, take much longer to solve if we do at all. I have active flashblock, and sometimes the error occurs before I got the chance to activate the video and sometimes after, but occurs systematically. In addition, on this kind of site, the error "the script is not responding" will also go on which most of the time, which I have not seen anywhere else, which means that the only solution, after a certain time must end the process in the Task Manager. Sometimes, I tried to play the same video for half an hour without success.

    As I have spent some time in the Task Manager, I noticed that I find myself with many processes running for FlashPlayerPlugin_15_0_0_152.exe * 32 (Description: Adobe Flash Player 15.0 r0.) They accumulate more I use firefox, but disappear when I restart my computer. I'm away until at least 50 at any given time. Most use 128 or 124 K of memory, but about 1 in 7 uses between 1-5000 K. I don't know if it is related to these issues, but I only noticed it since it was started.

    I tried to reset firefox and it changed nothing of the above.
    If it helps, I've used Windows 7. Do not hesitate to ask for more details on my system and I will do my best to answer, although I'm not a computer expert. Thank you very much in advance for your help.

    Please update to version 32 and make sure that it also does not happen with the disabled extensions/addons.

    Vista and Windows 7 updated drivers love then here's how update the most important.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now, click on update
    Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
    Uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    Updates, that leaves about Windows updates but it will not install the drivers that will be generally
    older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then

  • Mobile data does not and the name of the Access Point settings are not available

    I don't have a mobile data, not even the small up and down arrows or letters beside the sims signal bars appear.

    I tried all the troubleshooting settings and different type of network, the airplane mode is off, mobile data are no limit, no power save modes are on. Phone is dual sim so I tried on the two sims and tried to disable the other sim and changing the sim slots, both sims are loaded with a credit of data that works in other android devices. WiFi works fine. Factory reset does not help.

    There is that one thing that I can't not try troubleshooting. When I select settings > more > mobile networks > access point names, it says

    "Access Point name settings are not available for this user.

    Maybe if I could put APN I could get mobile data. How can I do or how I can try to get mobile data to work?

    This text is a bit misleading, which is something that I have forwarded internally as your comments.

    If you have no NPP stored the phone displays the text "the name of the Access Point settings are not available for this user" even if you use the owner account and have access to the settings.

    Try to download the automatic settings from settings-> more-> Internet settings and see if that helps.

  • HP Envy 15 "touch screen power LED appears, but the fans does not and the screen does not light

    Hello!

    I'm a student in computer engineering at the University of Waterloo 1A, and I run a very serious problem with my HP Envy 15 "TouchSmart laptop computer running Windows 8.1. It is a problem that just started today, and I'd rather have a first support here before going to see the technical support Office sometimes tomorrow. It has to do with the screen and the fans where the Power LED lights in white, just as when the laptop works properly.

    (I have warranty on the laptop when it was purchased last June, except that if I find that I need to get a replacement, I'll lose all my work, I did on that since I started my semester.) It's so silly of me not to have all my work saved on a backup, because I have an external hard drive. Problem is, I've had too many problems in getting myself organized, I'm not being open-minded as I should, and worse, I'm not a balance between life and work at home.)

    Before I had my MATH 117 conference (Calculus 1 Engineering), I was in a nearby lab where my laptop was open and turned, works correctly. I've had NetBeans IDE running since I wanted to work on the second part of my current assignment of CS 137 (principles of programming). Because it was almost time for my presentation, I closed the laptop by simply moving the screen down on the keyboard, where it goes into mode 'sleep'. (Whenever I flip to the top of the screen, the laptop is supposed to return, and the sliding screen of Windows 8.1 connection will appear.)

    When I took my seat for reading, I wanted to spend a little time to work on my programming assignment. However, after the reversal of the screen to the top, instead of having the login screen appears, I encountered the problem: the power supply light is showing a white light, but I don't hear the fans between the ventilation openings on the left side of the laptop and the screen does not light. I tried to take the power for several seconds and once button at least 10 seconds, except that the power light continues to display on a white light. The Commission of the Wi - Fi light is not displayed.

    Whatever it is, I don't want to take out the battery because I have that on my last laptop, and it's from there that I couldn't turn to the former, a new market. If I leave the Envy laptop battery, it will short-circuit the connections between the battery and the computer, and so several components will FRY. For now, what I do let the laptop is to empty the load on the battery. Then, once I noticed that the power light does not project a white light, or plug in the AC adapter and try turning the laptop on the power button.

    It will take a little while for the circuit drain the load on my battery but...

    Anyway, please would you be kind enough to help me with this problem? I would really appreciate if you can give me several recommendations. Thank you!

  • Keypad does not and the volume keys not working not

    I had this problem since I got this laptop, the pad and the volume keys don't work.

    I tried to uncheck keys mouse in Control Panel, but they still do not work, I put on a frame, so it makes a noise whenever you click on capslock and numeric keypad. However when I press numlock that noise does not turn on, I just wanted to make sure that there is a way out maybe solve this before I take it to the store.

    Looks like a defective keyboard that should have been replaced under warranty.  It won't be cheap to replace.  You will need a technician because it involves a lot of disassemble very delicate pieces.  Make sure that the technician replaces with the correct part.  There are a lot of almost the same thing available.

  • WiFi radio adapter off, the USB ports does not and the Bluetooth adapter is no longer visible... Please help!

    I had my laptop Dell Vostro repaired under insurance in January 2013 after a spill of liquid.  HAAC Ltd. has replaced most of the laptop - but the return, the SD card did not work.  This seems to be due to the engineer he connects not properly and the company recommended it and returned it to me again.  A couple of months, I found my USB was temperamental - so is my built in Bluetooth adapter.   Last month - the wifi does not work for most of the time either so I have to connect to my router by wire.

    This could be a problem in windows 7 - all my problems seem to be related to network adapters.  If it's a hardware problem - does anyone know if it could be another loose connection?  HAAC Ltd. only give a 3 month warranty on parts that seems just a little.  But if this anomaly is due to the production of poor quality - that is not properly connect the laptop then I'll go back their again if they are responsible.

    By the way – there's a switch wifi on the front of the laptop - but is not currently be recognized.

    If anyone has settings that I could check that can help - especially if some inhibit the use of wifi.

    Thank you very much

    Hello

    Your wifi switch not recognized is probably a hardware problem. The rest could be a hardware or software problem.

    Method 1:

    Lets start by doing a reset to coercive. Follow these steps:

    1. Unplug the notebook (remove power cord), then remove the battery.
    2. Disconnect all USB devices and the connections between the USB ports.
    3. Let the laptop only for several minutes.
    4. Then plug the power cord without connecting the USB devices. Then replace the battery.
    5. Plug each device in turn, allowing them to load the drivers of devices one at a time (plug in the appliance and wait its loading all its drivers before installing the next USB).

    The computer recognizes the USB ports? All of them or none of them?

    Method 2:

    Open Control Panel, Manager of design. Click the view tab, and then click Show all devices. From there, you can remove all instances of USB devices and restart the computer to see if the problem resolves. Repeat this procedure with the wireless adapter (uninstall and reinstall, ensuring that there is only one instance of the wireless adapter).

    Method 3:

    Create a new user account by following the instructions in this article:   http://windows.microsoft.com/en-US/Windows7/Create-a-user-account . Does this solve the problem?  If the problem is resolved in a new user account, this means that the old user profile is damaged. Here is the link to repair a damaged user account: http://windows.microsoft.com/en-us/windows7/Fix-a-corrupted-user-profile.

    Try these methods and post your results here. I'll be here waiting for the results!

    Kind regards
