Google Analytics Screen Time Incorrect when using Measurement Protocol

I am using the measurement protocol for my Tizen TV application since I cannot use the JS (requires a domain name) nor Android/iOS SDKs.

I am sending

{         v: 1,         tid: GA_TRACKING_ID,         cid: data.deviceId,         t: 'screenview',         dh: 'something.com',         dp: encodeURIComponent($location.path()),         cd: transition.to().title + ($stateParams.gaTitle ? ' (' + $stateParams.gaTitle + ')' : '') || 'Unknown',         an: 'XXX',         'ga:mobileDeviceModel': data.deviceModel } 

To https://www.google-analytics.com/collect

But the screen times seem off its always in the seconds eg. 30s etc. I tested staying on page for a long time but it does not seem correctly reflected. I guess its because I only send this hit once and theres no way for Google to know when it stopped? Is there a way to fix this?

First you need to decide on the session timeout (Admin->property->tracking.js) the default of 30 minutes means you will need to generate hits at intervals bellow 30 minutes to prevent new hits from being in a new session.

Then you need to make sure hits are frequent enough and include their current page/screen names, for example:

{ // start video         v: 1,         tid: GA_TRACKING_ID,         cid: data.deviceId,         t: 'screenview',         dh: 'something.com',         dp: encodeURIComponent($location.path()),         cd: transition.to().title + ($stateParams.gaTitle ? ' (' + $stateParams.gaTitle + ')' : '') || 'Unknown',         an: 'XXX',         'ga:mobileDeviceModel': data.deviceModel } { // < 30 minutes later         v: 1,         tid: GA_TRACKING_ID,         cid: data.deviceId,         t: 'event',         ec: 'Inactivity',         ea: 'Watching Video',         el: ..video name..,         ev: 28,         ni: 1,  // doesn't count as interaction          dh: 'something.com',         dp: encodeURIComponent($location.path()),         cd: transition.to().title + ($stateParams.gaTitle ? ' (' + $stateParams.gaTitle + ')' : '') || 'Unknown',         an: 'XXX',         'ga:mobileDeviceModel': data.deviceModel } {  // user does something (can wait 30 minutes more before a new ni event)         v: 1,         tid: GA_TRACKING_ID,         cid: data.deviceId,         t: 'event',         ec: 'Activity',         ea: 'Volume Adjustment Down',         el: ..video name..,         ev: 5,         ni: 0,         dh: 'something.com',         dp: encodeURIComponent($location.path()),         cd: transition.to().title + ($stateParams.gaTitle ? ' (' + $stateParams.gaTitle + ')' : '') || 'Unknown',         an: 'XXX',         'ga:mobileDeviceModel': data.deviceModel } {  // user goes to new screen (also calculated as the end of screen time)         v: 1,         tid: GA_TRACKING_ID,         cid: data.deviceId,         t: 'screenview',         dh: 'something.com',         dp: encodeURIComponent($location.path()),         cd: 'somewhere else',         an: 'XXX',         'ga:mobileDeviceModel': data.deviceModel } 

If you have the ability to send on all exit events then you may want to use queue time on exit (or every 4 hours) to calculate for the session after all the data for the period is in.

Google Analytics' session calculating is based on interaction from the user. If the user clicks, the session gets a heartbeat. If the user is watching a movie (TV e.g.) it wont be interacting with your application and the session stops
