N95 Camera issue

[sandy_zeng]

Hi:

I am using the Camera example (S60_Platform_Camera_Example_with_AutoFocus_Support_v2_1_en.zip)for my application. the example runs fine on N95, but when I embed this software in my application, it gives me the following information when I try to access the camera:

unable to execute file for security reason:

this is my setting in the mmp file


TARGET OcrExample.exe
TARGETTYPE exe
UID 0x0 0xA00001F3
VENDORID 0x0
//EPOCSTACKSIZE 0x5000
//EPOCHEAPSIZE 0x5000


CAPABILITY UserEnvironment // SwEvent required to capture
// events from camera shutter key

START RESOURCE OcrExample.rss
HEADER
TARGETPATH resource\apps
END

START RESOURCE OcrExample_reg.rss
#ifdef WINSCW
TARGETPATH \private\10003a3f\apps

TARGETPATH \private\10003a3f\import\apps
#endif
END


#ifdef WINSCW

LIBRARY CamAutoFocus.lib

#else

STATICLIBRARY CamAutoFocus_s.lib
#endif

LANG SC

and this is the MMP file i got from the camera example


TARGET CameraApp.exe
TARGETTYPE exe

// End of file

the different is that in the camera example, it specifies the security id (identical to the UID3), also know that it specify the UID3 as 0xExxxxxxxx, while my application starts with 0x1xxxxxxxxxxx...is this the reason I get the security check fail?
what can I do to remove this security check? I try to apply for the Symbian signed key, but it seems to be no response


Thank you very much for your answering

[mopa]

have you certificated your app with a developer certificate?

[sandy_zeng]

currently I can only get the self sign certificate..

I am new to Symbian and I just send the email according to the following website

https://www.symbiansigned.com/app/page

but so far, i have not got any reply...is there any solution to this?

[kkrish]

for the following capability symbian signing or developer certificate is not mandatory

LocalServices
ReadUserData
WriteUserData
UserEnvironment
NetworkServices
Location

[sandy_zeng]

yeah, i also see this in the Symbian document.

The problem is that I uses the UserEnvironment but it gives me the stated error (secuirity reasons)....do you have any hint on this or any solution to this?

...this is my setting in the mmp file


...CAPABILITY UserEnvironment // SwEvent required to capture

...

you need a developer certificate to have SwEvent granted for your application.Self-signing isn't enough


best regards

[sandy_zeng]

any other solution?

according to the document,

2.20 What certifications do the capabilities require?
The capabilities that require Symbian Signed are listed below (for capabilities marked with an asterisk Symbian Signed certification is preferred but not mandatory, as the user can grant the capability at the installation time):
Version 2.0 | April 13, 2006
S60 Platform: Symbian Platform Security FAQ | 14

...

For SwEvent, SymbianSigned is mandatory, as user can't grant it


best regards

[sandy_zeng]

does that mean if I don't handle any HandleKeyEventL(const TKeyEvent& aKeyEvent, TEventCode aType) (i.e. always return EKeyWasNotConsumed), then I am ok to use the camera without using the Symbian signed certification?

[wizard_hu_]

CAPABILITY UserEnvironment // SwEvent required to capture
// events from camera shutter key

It is not that hard to read: SwEvent required to capture events from camera shutter key. Camera shutter key is the camera shutter key, you might consider living without it as a first try.
Related portions of code:

// try to capture events from the camera shutter key
// (SwEvent capability required)
iCameraKeyHandle = iCoeEnv->RootWin().CaptureKey( EKeyCameraShutter, 0, 0 );

and

case EKeyOK:
case EKeyCamera:
case EKeyCameraShutter:
{
DoSnapL();
return EKeyWasConsumed;
}

If you can live with pressing the OK key instead of the dedicated shutter key, you do not need SwEvent capability, and self-signing is enough (UserEnvironment is user grantable).
If the application refuses to run, you might want to comment the CaptureKey-line. However it should fail silently, I think.

[sandy_zeng]

problem solved..I just disable it and it works ..


another problem is how to adjust the resolution of the camera? currently it is on;y 0.8 mega pixel...how to adjust the parameter so that I can get the resolution as large as possible?

for the following capability symbian signing or developer certificate is not mandatory

LocalServices
ReadUserData
WriteUserData
UserEnvironment
NetworkServices
Location

On S60 Symbian Signing or a developer certificate is compulsory for Location. It seems to be this that has brought the Symbian Signed web site to its knees since the launch of the N95 with many people trying to get developer certificates to sign pirated location-using applications.

[sandy_zeng]

how this relate to adjust the resolution?

Switch to threaded mode to display the posts and you'll see my reply was to a post earlier in this discussion, not to your question about resolution. I quoted the earlier reply too.
