I try to set the lock screen wallpaper from my application but i have a problem.
I use below code
//set the lock screen background image
String filepath = App::GetInstance()->GetAppResourcePath() + L"screen-density-xhigh/back.jpg";
String key(L"http://tizen.org/setting/screen.wallpaper.lock");
SettingInfo::SetValue(key,filepath);
but the result is not the expected. The lock screen wallpaper changes but with a black one and not the specified wallpaper.
I have the privilege http://tizen.org/privilege/setting in the config.xml
