Stop the screen turn on mobile devices

• App background stops when the screen turns off

  I wrote an Android app with a Service that receives events from the LocationService and the accelerometer and always try now to wear 10 BlackBerry. Tests on a Z10 STL100-2 10.1.0.4181

  Once the unit has remained unchanged for some time, the location listener is not registered, in order to save energy, and re-recorded a trip again.

  Don't worry, this can be disabled via the visible activity. But it must continue with the last State (start/stop) after the reboot.

  I even magically figured out how to add additional permissions for the manifest of BAR: "_sys_android_autostart_service" and "run_when_backgrounded".

  But as soon as the screen turns off, my application stops working. No location or accelerometer case being received. Turn on the display again, everything back to normal.

  It is meant to be a question about the accelerometer, but I could not find in the tracker.

  So my questions are:

  -Is it possible to port Android continue to receive events location when the screen is off?

  -Is it possible to port Android continue to receive events of accelerometer when the screen is off?

  -Will my service to continue to operate if more than 8 Apps began after mine? (And the user did not hit the close button)

  -The "headless" 10.2 mode help? (I currently only test with 10.1, because my service provider has not yet unlocked 10.2)

  -Finally, this would be possible with a native application? (I could port the port iOS... lots of fun...)

  Thank you very much for your help!

  PS: If it's of any interest: I use the plugin V1.6.1 Eclipse/ADT to package and install the bar.

  As reported here as well (and I'm sure in other places)

  I'm working on a deal in the next version, similar to what we're doing with location requests (in other words, activate us the background mode if your app acquires a partial wake lock).

  Edit:

  So my questions are:

  -Is it possible to port Android continue to receive events location when the screen is off?

  (Yes, but you must hold a wake lock).

  -Is it possible to port Android continue to receive events of accelerometer when the screen is off?

  (For the moment, no, but I'll change that, so it behaves like location.)  Mind you, this could be used to work on old revisions of the software until the native sensors team added a background of sensor mode which is disabled by default and must be explicitly enabled).

  -Will my service to continue to operate if more than 8 Apps began after mine? (And the user did not hit the close button)

  (There are a lot of thing that matters if your Services happens to run or not, which is not limited to, but includes the number of applications already running and the status of the device memory).

  -The "headless" 10.2 mode help? (I currently only test with 10.1, because my service provider has not yet unlocked 10.2)

  (No, it's a native thing.  Your application is already technically without head)

• Prevents the screen turn off (locked)

  The screen turns off after a short period, as configured in the settings. But sometimes this must be disabled by software, for example the navigation software should not leave the screen get black. (BlackBerry Maps seem to handle this...)

  There are other situations where it might be a good idea to leave the screen in Active mode, perhaps the media players (watch the video) and so on.

  The page settings of the device even informs me in the operative part of security/password on the fact, that applications could extend the time until that the device will be locked with password.

  But I can't find any documentation on how the two that can be made from code.

  What permission is needed and I have to call?

  Hello

  Copy the following code prevents the lock screen:

  #include 
  ...
  Application::instance()->mainWindow()->setScreenIdleMode(ScreenIdleMode::KeepAwake);
  

• What signal is emitted in the ListView, when one of its cells appears in or from the screen turns off?

  What signal is emitted in the ListView, when one of its cells appears in or from the screen turns off?

  I created listView with custom listItemComponents

  Is there any signal when listItemComponent go to the screen?

  Currently, it is not possible to detect if the cells turns off the screen. Even if you join LayoutUpdateHandler them they will just stop send updates when you go off the screen. I managed to hack a solution using a timer, but I guess that a cleaner approach would more use a ScrollView with CustomControls instead:

  1. get the dimensions of the ScrollView joining ScrollView LayoutUpdateHandler.

  2. attach the LayoutUpdateHandlers to the CustomControls.

  UPD: It is also viewableArea & viewableAreaChanged event scrollView property.

  3. If the controls that were inside the visible area of the ScrollView went outside, raises the event.

  Of course re-use of cell works that way.

  It's so easy to grab the cell on the screen:

  If you use ListItemProvider, updateItem() function is called when the element appears on the screen:

  https://developer.BlackBerry.com/Cascades/reference/bb__cascades__listitemprovider.html

  It will also be called if the data item are updated in the model.

  When the item is created for the first time, createItem() is called.

• Access code is lost as soon as the screen turns off

  When I turn my wrist after that my Apple Watch screen exploded, I need to enter the access code. I turn on the wrist, the screen turns off, I turn back, screen lights up, I need to re-enter the password. And so on and so forth. The watch does not maintain the code.

  I am white white, is not dense hairs on my wrist, no tattoos and I wear the watch very well on my skin.

  The funny thing is: it is a replacement watch, I got today. The other had the same problem, but this is probably because the bottom of the watch with the sensors fell, must have damaged the sensor cable. But this one is brand new.

  Hello

  Make sure the wrist detection is enabled:

  • On your iPhone, in the application of the watch, go to: My Watch (tab) > General > detection of wrist - turn on.

• Equium A20 fell and the screen turns off always

  Hi, I was using my satellite A20 long (4 years). Never had any problems. Recently he fell and the screen turns off always.

  I can see the toshiba logo and the windows logo also when starting, and even I can enter the BIOS and change the boot order too... but as soon as windows load screen is black. I don't understand

  Anyone with the solution?

  Thanks in advance...

  Hello

  > but as soon as windows load screen is black. I can t understand
  This means that the display output has accidentally changed to an external.

  Have you checked if something would be visible on the second external monitor?
  Select this check box.

  In addition I advise to use the FN + F5 keys to check if you can switch the output back to the internal display.

• Satellite 1800 - 752S - the screen turns off

  Hello world.
  I have a satellite 1800 - 752S.
  Since an ew months ithas a weird problem: the screen turns off. If I press and release the button the lid on what it is, but after that turns off again quickly. OT goes off sometimes immediately, sometimes after a few minutes, or even hours. Sometimes it provides be when I run out of battery and bothers me on AC, sometimes against. It works fine, after I turn sleep or hibernation several times, and after a reboot, it bothers me. I've updated his BIOS for the lates on this site, which would not help. I guess it's a hardware problem, because it's the same problem under Linux, and I tried to install different versions of drivers and windows (not only the one of the recovery CD). Anyone have the same problem before. Any help will be appreciated.
  Thank you very much
  Roman

  Hello

  I think you're right, it's a hardware problem. But to be sure, try connecting an external monitor. If it works without problem while laptops, screen turns off, then it must be a hardware failure.

  I guess it's a problem with the FL inverter. You have to give your machine a service partner Toshiba for repair.

  Good bye

• Anyway continue Voiceover if the screen turns off?

  Hello world

  I use Voiceover to read eBooks for me, but the voice-over goes out once the auto lock turns off the display.

  Is it possible to do the Voiceover to continue even if the screen turns off?

  Thanks for your help!

  Hi Dionysus17,

  AFAIK the only way to solve this problem is to disable the auto-lock on your iPad. To do this, go to settings > General > lock and from here you can choose when you want to stay for before your locks iPad screen.

  Hope this helps,
