how to trigger a launch of a .sis/.sisx via call status

**vj018** · 2009-11-13, 09:51

Hi to forum nokia experts and users. Is there a way on how to launch a .sis/.sisx if the triggering event is when the mobile phone user calls? and also, if that's possible, how could I integrate that code on carbide c++? We are new to the IDE and we are still learning on that. Our project is about mobile security wherein a mobile phone is connected via bluetooth to our prototype(bluetooth bracelet). If the mobile phone(or the bracelet) goes out of range within the other device, automatic the mobile phone cannot do outbound calls. Hope that someone can help. Thank you so much in advance for helping us.

I think the phone must app/exe running on it and lt will listen for incoming/outgoing call.

When you dial a call you can install your sis file using SW_Installer_Launcher_API

First of all, clarify your requirements to yourself. Installing a .sisx file on every phone call is hardly something that you could benefit from.
Then you can find various examples/documentation about detecting and tracking phone calls, just check the SDK Help and the Wiki. The related API is CTelephony
Examples for BT communication also exist, Bluetooth is a good keyword for locating them. For a simple present/not present level of detection you may want to combine RHostResolver into the search, since that is an API which is able to scan for nearby BT devices.
For breaking unauthorized call attempts, you can go for hacks based on simulating a keypress for the red button, or you can also go for the internal telephony API-s via API partnering.
When you are ready, search for autostart in the Wiki, in order to have your code always running on the devices.
