Symbian sis文件安装失败

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!
