Piwik for Android SDK - Battery Usage #91

Closed bmorrisidm closed 8 years ago

bmorrisidm commented 8 years ago

Hi there,

As per this thread I am posting here

https://forum.piwik.org/t/piwik-for-android-sdk-battery-usage/18623

We've looked at this a bit more and it looks like Piwik does do dispatching, every 2 minutes we think. However the question still stands regarding battery usage and addressing the points in this article which seems to indicate app tracking is very difficult.

Also if it uses dispatching is it impossible to gather all hits or is that a Google Play Services issue and Piwik doesn't use that.

Thanks for any feedback.

The manual dispatch on minimize/close app seems to be a reasonable solution in this case. For now I can recommend You to reduce dispatching interval: it shouldn't affect battery usage, but it wouldn't give You 100% tracking accuracy.

The client-side app tracking part is not computationally difficult and unless mistakes were made the impact on batterylife is neglible.

Piwik is more like Google Analytics, not Google Tag Manager. http://stackoverflow.com/questions/23640645/what-is-the-difference-between-google-tag-manager-and-google-analytics

The impact of a few misses on ccuracy is also minor in larger products due to the volume of hits. The SDK's prevalent reason for missing hits is currently loss of network connectivity (#16).

Seems solved.
