Subject [jira] [Updated] (CB-2637) Speed up contacts find by ignoring entries with specified null fields
Date Mon, 22 Apr 2013 23:59:16 GMT


Joe Bowser updated CB-2637:

    Component/s: Android
    Environment:     (was: Android)
> Speed up contacts find by ignoring entries with specified null fields
> ---------------------------------------------------------------------
>                 Key: CB-2637
>                 URL:
>             Project: Apache Cordova
>          Issue Type: Improvement
>          Components: Android
>            Reporter: Nestor Soign
>              Labels: contacts
> Finding contacts is very slow: roughly 1 second per 100 contacts on recent hardware.
According to the current major speed limitation
is the number of contacts returned by find. 
> I have noticed that a large percentage of contacts appear to be either incomplete or
lack email addresses or phone numbers, since Google combines phone and email contacts into
a single list. 
> Many applications may be interested only in contacts which have phone numbers or which
have email, or which have either. By allowing specification of fields which are required to
be non-null, contacts.find calls could be sped up significantly for those cases. 
> For example, I have a contacts list with 2641 contacts in it. Of those, 614 have telephone
numbers but no emails. 1134 have emails but no telephone numbers. 203 have both emails and
telephone numbers, and the remainder appear to be malformed and useless. 
> A contacts.find call on my phone (HTC EVO 4G LTE running Android 4.1.1) takes about 13
seconds to complete, but if it could be limited to only contacts with telephone numbers, it
would probably take about 3-4 seconds. Even if it were limited to contacts with either a telephone
number or an email, it would probably take about 9-10 seconds, still a substantial improvement.

> If this is easy to implement it would be very helpful in many applications.
