• Using C++ in QML classes in app without head: refers to 'bb::device:VibrationController:staticMetaObject' the undefined

  Hi, I've been weeks of work on the BB and had a lot of problems. Some of them have been resolved, some were not without the support of the forum.

  Now I have a great difficulty that I can't find answer by Googling.

  I am grateful to some body can help.

  Here's a simple case that make the big problem for me:

  1. create an app without head with Momentics. 2 project will be generated HeadlessApp and HeadlessAppService.

  Without modification, this code works well.

  2. I'm link below to use VibrationController in HeadlessAppService: https://developer.blackberry.com/native/documentation/dev/integrating_cpp_qml/index.html#usingcclass...

  below the code has been added:

  -Add codes below to main.cpp HeadlessAppService

  #include 
  using namespace bb::device;
  

  then add qmlRegisterType as below

  Q_DECL_EXPORT int main(int argc, char **argv)
  {
  
     Application app(argc, argv);
  
     qmlRegisterType("bb.vibrationController", 1, 0, "VibrationController");
     ApplicationUI appui;
     return Application::exec();
  }
  

  3. to confirm the new code, I just right click on the project and select build project.

  Bang! I got several error I don't understand. (red lines are errors)

  Why adding simple code can be a problem? Please help me!

  Thank you very much!

  You must add this code into main.cpp to your HeadlessApp, not HeadlessAppService. Your spare part cannot run any UI stuff, trying to save an object any for QML is part of the things in the user interface.

  But anyway, reading your newspaper from the console, you seem to put in the right place anyway. Did you add this to your headlessTest.pro file:
  LIBS +=-lbbdevice

• App without head

  Hello guys what changes do I need to change in the CPC or hpp files to convert my simple app in app without head
  I have already added

  LIBS += -lbbplatform
  

  in my .pro file and take a permission to Run in backround (_sys_run_headless) & (sys_headless_nonstop) also... bar - descriptor.xml

  I suggest that you either look at the example app without head or just start with that and add your own code.

• App without head: how to check the status

  1. I read this on the BB site:

  Criticism	Process that must be running at all times (for example, system processes)
  In the foreground	Processes that are running in the foreground
  Background	Processes that run in the background
  Stop	Process involved in RAM without running

  The question is can we write the code to check the States of the app to trigger certain activities?

  I also want to know the other possible States of the life cycle such as: "application started", "closed app"...

  A problem critical of the app without head is memory management, and we can only until BB have a better explanation on the life cycle of the app without a head.

  2. for an application in the short-term, event after 20 years, the app is still listed on memory and CPU usage. That seems abnormal, because I guess that after 20 years, the application will be stopped and not be able to use the memory and CPU more.

  Can someone explain?

  Thank you very much!

  Would you like to take a look at this app, I wrote that has a component without head and uses QLocalSocket to communicate between the headless and the (https://github.com/blackberry/Cascades-Community-Samples/tree/master/wakemebybeacon) user interface process. There is also a blog explaining how it works here: http://devblog.blackberry.com/2014/07/wake-my-beacon/.

  You can detect changes in status of process on the part without head like this (https://github.com/blackberry/Cascades-Community-Samples/blob/master/wakemebybeacon/WakeMeByBeaconSe...) and manipulate them like this (https://github.com/blackberry/Cascades-Community-Samples/blob/master/wakemebybeacon/WakeMeByBeaconSe...).

  When a component without a head (process) is distributed will be passable for 20 seconds, after which it is moved to a queue where it receives no processor, but can be awakened (marked as executable) of certain classes of events. While stopped the headless process always retains a memory footprint, but is not available.

• Citing the part of the user interface of the game without head in an app without head

  Hello

  I try to call my interface section user app without head of service class (part long term without a head), as shown below:

  If you have the NoScript extension or other blocking JavaScript extensions (addons > Extensions), you must allow (or temporarily allow) the IP address of your router. Any particular setting should be held in Firefox itself.

• Problem with connecting to Windows normally

  OK, so I'm having a problem with a record in my laptop normally and the only way I can get to it is by going to safe mode.

  Basically what happens is that whenever I try to connect my computer normally (not in safe mode) I'll type in my password press enter it will come with the welcome sign and this small circle that tells it to load but it never is as if this drive does not work because the lamp flashes not or anything like that. However, it is very well whenever I login in safe mode and that the laptop came with windows vista on it that I don't have a copy of windows vista to try and slove the problem. This problem acerd after I restarted my laptop because it was slow and contributing generally to make it work properly again, but now this has happened and I don't know what to do.

  If someone could help me? I really need my laptop back to normal because right now, it's my only access to internet that not working I really on heavly for my college.

  Thank you for taking the time to read this and thanks for teying to help me.

  Hi Lexiey,

  A. recent changes made on your computer?

  B. you get any error message?

  You can start in safe mode, and then you put a computer to boot and then restart the computer in normal mode controls whether the issue persits.

  A clean boot helps eliminate software conflicts.  Let us check if software is causing the problem by following the clean boot procedure.  To perform the clean boot procedure, follow the instructions in the link below.

  Step 1: Perform a clean boot
  Step 2: Enable half the services
  Step 3: Determine whether the problem returns
  Step 4: Enable half of the startup items
  Step 5: Determine whether the problem returns
  Step 6: Resolve the problem
  Step 7: Reset the computer in normal mode and check if the problem persists.

• Problem with app without head

  I have an app without very simple head with a spare part which can be summed up like this:

  int main()

  {

  While (true)

  {

  appendToLogFile();

  Sleep (5);

  }

  }

  He manages to write twice in the logfile on Simulator 10.3 after the system starts and then it dies (nothing is printed, process went from "pidin").

  Is there something I need to do to ensure that the system does not not kill us after a few seconds?

  I have the following 2 lines in bar - descriptor.xml:

  _sys_run_headless

  _sys_headless_nostop

  I can zip from the project and set up somewhere if anyone wants. It is based on the project template that Momentics puts apps headless.

  TIA.

  I did some experiments. It seems that headless apps work pretty much as advertised during the development of a device but not very well at all in the development on the Simulator.

  Use a device to develop applications without head, not the Simulator.

  Perhaps future simulators will correct the current problems.

• Problem with the EMU 9 and App volume 2.10

  I'm surprised that no one else has made the experience... but if you have 9 EMU with App volume 2.10 any stacked application that connects to an external system like vsphere client, Remote Desktop Manager, xming or similar opens but you get what looks like a firewall, dns on winsock error.   I tried the following while Troubleshooting which lead me to discover the EMU 9 > 2.10 AppVolumes question.  Do not forget that all the problems described were nonexistent before the upgrade to the EMU 9.

  1. create new vm of capture for the volumes of the app
  2. created piles of individual application for customer xming, DRC, termnals, vpshere
  3. created a desire unique appstack applications
  4. installed applications on the write-able volume with the same results
  5. remove all agents and install them in the correct order
  6. 9 removing MEU... Bingo appstacks work
  7. tested all combinations of the appstacks and they work all all users as EMU 9.0 is not installed.

  I don't have app blocking (its off by default) and I don't think that there are other settings in EMU who wanted to have that effect.  I also looked around and found no problem of compatibility between the EMU 9 and volume 2.10 on any doc App.

  I'm going to downgrade the agent of EMU on the endpoints to 8.7 and test

  finally found the issue...   KB https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2145681
