I tried to port Qt app to BB10 using Qnx Ide V 10.2.1.The application is purely in Qt not cascades.But i create my project in the ide as blackberry cascades project.The application runs successfully in Device Debug Mode for the target device.I use Z10 as target but after signing the app using export release bulid in bar descriptor.xml .
The signed bar is generated in arm/o.le-v7.I installed that bar file into my device.After installation i tried to launch the app,but it failed to launch.So please help in this regard.
Solved! Go to Solution.

Look at your processes using the Momentics - QNX System Information perspective and see if the process is still running. If it is then right click on the process and send a kill signal.
Just to clarify there is a difference between 'Running' a release on your device and sideloading a signed exported app, mainly the former is easier to debug.
Have you tried the Run option in Momentics and does it crash?

Ok but are you saying the app only runs properly for a debug build, in which case you have a memory leak or memory access problem and there may be something you can see in the log file explaining why when running the release build.
Alternatively you can look at the backtrace.
If the crash only happens in the export build this is a lot harder problem to diagnose.

Feel free to write more words than you are currently doing so this doesn't turn in to a 100 post thread.
Explain exactly the point at which it crashes, app window, splash screen, blank screen, further on.
Explain what you have looked at in the way of debugging so far.
Let me know if you've checked all the right permissions for anything you might access.

I use QNX Momentics IDE for BlackBerry 10 Native SDK Version: 10.2.1 for development.
I create my project in IDE as New/ Blackberry project/ New Blackberry project/Application/cascades/standard empty project.My app is Qt based and not cascades so my app don't have qml file for UI.The app is a game application so no specific permission is added.
The app ,loads and runs for Build configuration ->setactive->Device-Debug and Run configuration->Device-Debug.
The app fails to load with problem occurred " Unable to release application on target" for Build configuration ->setactive->Device-Release and Run configuration->Device-Release.
When i tried to export release build the signed bar file is generated in arm/o.le-v7/appname.bar,which i installed in my target device.After installing i tried to launch the app but it crashes immediately with a blank screen.
I don't have splash screen in my app.
