Off line Usage

[thanasio]

Hi,

assume that we have a simple app with a button and a page and we have written code t track the button click event and page view. What happens if a user visits the page and clicks the button off-line?

Does CPA cache the request? If yes how long does the request stay live? When and how CPA attempts to resend the collection request?

Cheers,
T

CPA does not cache the request. Hits sent while a device is not connected will never be delivered to Google Analytics.

That's not to say we don't think offline support is a good idea. It is. And we want to add it. But we don't want to cache a zillion hits then bog down a connection with that thar zillion hits when a device comes back online. Once a reasonable batch delivery mechanism is available to us, we can talk about getting this implemented.

Is such a mechanism now available now?

Batch requests can be made using measurement protocol:
https://developers.google.com/analytics/devguides/collection/protocol/v1/devguide#batch

The app could cache data and when comes back online process the data and send the data to GA. There are however limitations. Only 20 hits per request and payload size limits apply. So it may require more than one request to send data but it can be done in idle state.

Anyway it would be a great feature.
