c# - SensorCore with CameraCaptureTask -

in our wp 8.1 application, we're using sensorcore sdk collect information movements of user, , use cameracapturetask too. when launch task cameracapturetask.show(), application crashes, before capture, after, , after event completed, , message in vs 2013 : 'the program '[2512] aghost.exe' has exited code -1073741819 (0xc0000005) 'access violation'.' however, capabilities activated, , exact same piece of code work without sensorcore activated. use lumia 635.

any ideas ?​

are deactivating sensorcore related stuff before navigating away/showing task? need that, otherwise app crashes.

read sensorcore essential practices. there code samples both silverlight , winrt on how deactivate sensors.

for example:

protected override async void onnavigatingfrom(navigatingcanceleventargs e)  {     await _stepcounter.deactivateasync();  }
