Problem launching app CAknKeySoundSystem->iKeySounds->AddAppSoundInfoListL(R_MYAPP_S

[david.2.sanchez@nokia.com]

When launching my app I get the message "Unable to execute file for security reasons." I thought getting a developer certificate and UID in the protected range would fix it but it didn't code is below.

XXAppUi.h
CAknKeySoundSystem* iKeySounds;

XXAppUi.cpp
iKeySounds = KeySounds();
iKeySounds->AddAppSoundInfoListL(R_MYAPP_SOUND_LIST);

XX.rss
RESOURCE AVKON_SOUND_INFO_LIST r_myapp_sound_list
{
list =
{
AVKON_SOUND_INFO
{
sid = ERoshamboSoundWin;
file = "\\private\\20025B5B\\whoopy.au";
volume = 5;
},
AVKON_SOUND_INFO
{
sid = ERoshamboSoundLose;
file = "\\private\\20025B5B\\yeowch.au";
volume = 5;
},
AVKON_SOUND_INFO
{
sid = ERoshamboSoundDraw;
file = "\\private\\20025B5B\\boing_1.wav";
volume = 5;
}
};

XX.pkg
"C:\Symbian\Carbide\workspace\RockPaper\gfx\whoopy.au"
-"!:\private\20025B5B\whoopy.au"
"C:\Symbian\Carbide\workspace\RockPaper\gfx\yeoch.au"
-"!:\private\20025B5B\yeowch.au"
"C:\Symbian\Carbide\workspace\RockPaper\gfx\boing_1.wav"
-"!:\private\20025B5B\boing.wav"

I also tried using \resource\apps\<soundfile> location, no luck.
Thanks!!

You'll get that error when you don't have correct capabilities defined, thus check the epocwind.out in the emulator for missing capabilities and add them into your project.

also SDK docs often do specify what capabilities are required by the APIs and their functions.

Thanks for the help. I didn't check that before. In this case, the API says "Required Capabilities None"

I'm really just trying to play a custom sound. It plays System sounds fine. Do you know of any sample projects to implement the simple playing of a custom sound? I've actually been at this for a couple of weeks with no resolution.

In this case, the API says "Required Capabilities None"

Which API? Have you identified which API call fails?

"Unable to execute file for security reasons" says that your application can not be executed at all. So the problem is not about using the API, since usage of any API would happen after the application starts.
Make sure that the capabilities specified in your .mmp file are covered by your developer certificate. If you happen to use an own .dll, remember to the rule: a process can not load a .dll having less capabilities than the process itself.

And a side-note: private folder is private because other processes can not access it. The media server is considered as "other process" in this context, and it will not be able to access the audio files from your private folder.
