Overview

How to get a notification of user activity when the device has been idle?

Description

How to implement a mechanism that gives an application a notification of user activity when the device has been idle?

Solution

Write an "Activity Manager" CTimer that monitors InactivityTime. When the CTimer launches, do
TTimeIntervalSeconds inactiveTime = User::InactivityTime();
if (inactiveTime < KMyActivityManagerTimerInterval)
    {
    CTimer::Cancel();
    NotifyApplicationOfUserActivityL();
    }

Summary

You can implement an "Activity Manager" by using CTimer. When the timer launches, compare the timer interval to Inactivity Time. If the Inactivity Time is smaller than the timer interval, you know that there has been activity while the timer was counting.
