I want to start camera from my python application. It works well when I run app as a script (Choose->Run script), but if I make a sis-package, running this test program generates System error (-2) (in N70) or no error at all (6630).

Here is the simpliest example to reproduce the problem:

# default.py
import e32
try:
    # 6630, 6680
    # campath = u'z:\\system\\apps\\camcorder\\camcorder.app'
    # N70
    campath = u'z:\\system\\apps\\CamMojave\\CamMojave.app'
    appuifw.note(u"Starting camera")
    e32.start_exe(u'z:\\system\\programs\\apprun.exe', campath, 1)
    appuifw.note(u"Camera finished")
except:
    appuifw.note(u"Could not start camera")

I made sis-package with command
py2sisng.py --version=0.02 --uid=0x01361999 --appname=CamTest --lang=EN --verbose default.py camtest.sis

The real app I am coding works with out any other problems but this (as sis-packaged). Sis-packaged version produces System error (-50). (Not -2!)

Mysterious. Does somebody know the solution?

You forgot "import appuifw". The script environment has it already imported, but stand-alone apps do not. There are subtle differences like this that can bite you when packaging apps.

I tested the packaged version in my 6600 and it worked after adding the missing import (and changing campath to u'z:\\system\\apps\\camera\\camera.app').

You're right, I got the test program working also after adding this missing import.

Unfortunately my "real app" had already import appuif and your solution did not help in that case.

I'll keep debugging...

...but this import stuff lead me to the solution. Problem was not start_exe-related but import-related. It seems that script environment sees more modules than sis-packaged version. I added import sys and import os.path (used just before start_exe-part) and then sis-version started camera successfully.
