detect power interruption in Symbian OS

Question

Help , How can you detect whenever the power cord is unplugged from electrical socket through Symbian OS ?

Answer 1

The CTelephony API has a GetIndicator() method, which gives you flags including KIndChargerConnected. There's one set to tell you whether detecting charger connection is supported, and then if it is you check the other to tell you whether a charger is connected. Like HAL, you never know exactly what's supported. I've never used it so I can't give you examples of handsets which do or don't implement it.

You can register for notification of changes with the NotifyChange() method, using EIndicatorChange.

Answer 2

Duplicating the Symbian part of the answer from your jsr-256 question:

The Symbian OS C++ API to check battery status is:

CTelephony::TBatteryInfo
