How to measure how much time all users spend in the app with Google Analytics

Question

We have successfully implemented GA but one thing is still a riddle.

What I'm looking for is how much time (sum) users spend using the app. I need simple report with time period on the X axis and sum of minutes on the Y axis. This can help to measure user engagement in minutes during the time.

Did anyone figure how to implement it on Android and iOS?

Answer 1

Get it the start time and store it somewhere when the app starts.

long startTime = Calendar.getInstance().getTimeInMillis();

Also get the end time after the user logged in to the app.

long endTime = Calendar.getInstance().getTimeInMillis();

Get the time spent by the user.

long timeSpent = endTime - startTime;

Then use the 'GoogleAnalyticsTracker.getInstance().setCustomVar()' method to set this data inside your track event.
