Lockscreen with code - maemo.org

Is my day today

I open the second topic

I just started to use the code request to unlock my device.

But if i have the phone in this mode, i don't use the camera app if i don't insert the code after i open the lens cover.

I think is very useful if some developers allows to open only this app in this mode (with the open of the lens cover). Obviously, if you would to access at other apps, you must insert the request code.

What do you think?

the problem is that the camera app is an app such as everyone else. so you could bypass entering the code, if you open the camera and then end the program.

i thought about it yesterday. i had the same problem and thought about how this could be solved... but no proper solution :-(

i think that could possible insert the request code if we click on the X to close the app. Or not?

Code:

dbus-send --print-reply --system --type=method_call --dest=com.nokia.system_ui /com/nokia/system_ui/request com.nokia.system_ui.request.devlock_close string:'com.nokia.mce' string:'/com/nokia/mce/request' string:'com.nokia.mce.request' string:'devlock_callback' uint32:'0'

That should unlock the device without a code (yes, without a code).
It can be added to the app that's responsible for opening the camera when the lens is open, and when the lens is closed:

Code:

dbus-send --print-reply --system --type=method_call --dest=com.nokia.system_ui /com/nokia/system_ui/request com.nokia.system_ui.request.devlock_open string:'com.nokia.mce' string:'/com/nokia/mce/request' string:'com.nokia.mce.request' string:'devlock_callback' uint32:'3'

can be sent to lock it back.
Of course this has to be properly implemented otherwise it'd be a big security hole.

hmm yepp but what happens if the kammera app crashes somehow? you would need a daemon in the background that wait for closing the kamera application.
