[jira] [Resolved] (CB-1250) Speed up fetching of contacts on Android

Braden Shepherdson resolved CB-1250.
------------------------------------

    Resolution: Fixed

I submitted a change, which has been committed, to select only the columns we need. This has resulted, in my testing with 1400+ contacts, in a 4x speedup (from just over 40 seconds to just under 10 seconds).

It could still be better, but now around half the time is spent constructing JSON objects and shipping them through the bridge, which I can't see any way to streamline. The efforts to build a faster Android bridge should help this and any other operations with a large payload.

> Fetching all contacts on Android takes a long time when the user has many contacts (I have ~1450 and it takes 20-30 seconds). The Contacts app can load in less than a second, so what are we doing that's causing it to slow down?
> As an alternative or additional enhancement, add "limit" and "offset" functionality to the ContactFindOptions, to retrieve smaller subsets of the contacts more quickly.
