Symbian sis file installation failed

Question

Im developing a QT application which includes QTMobility and QContacts, QMessaging and QSystemInfo.

Following this documentation.

my .pro file has following capabilities

symbian::TARGET.CAPABILITY = LocalServices ReadUserData WriteUserData NetworkServices UserEnvironment ReadDeviceData WriteDeviceData Location

However while installing the sis file, I get the error "Requested application access not granted"

Am I missing some capabilities or are there too many of them

Answer 1

You have to sign you sis file with a valid certificate in order to install it. I assume that you use QT Creator IDE. It self-signs sis files by default. Self-signing can be used for the set of basic capabilities which include only:

ReadUserData WriteUserData NetworkServices LocalServices UserEnvironment

If you really need your application to use ReadDeviceData WriteDeviceData Location you must sign your sis file with a developer certificate. This is how you can get your certificate. You have several options here:

1. If you have a Publisher ID you can get a certificate at symbiansigned.com. To get a Publisher ID for 1 year will cost you $200 and to apply you must represent a registered organization. Individual developers can not apply for a Publisher ID.
2. Sign your sis file with Open Signed Online. It's free and anyone can use it. But you will have to go there and sign your sis each time you rebuild your application.
3. For a mere €1 you can become an Ovi Publisher. Registration is available for both companies and individual developers. After you register Ovi will provide you a developer certificate for up to 5 IMEI numbers of your test devices.

Hope this was helpful. Good luck!
