update lookup_uri in CallLog.Calls
<p>this is my first post here and i hope i follow the stackoverflow guidelines in a correct way. btw. english is not my native language, so if i express some certain questions or information in a  strange way, it might be because of the language.</p>

<p>anyway, i started to learn android only since a 1-2 months, so i don't know if my question is banal or not. so here it is:</p>

<p>i want to create a list of all recent calls by using the CallLog.Calls class. everything worked fine so far, but i realised that the lookup_uri column is always empty if the call is a new one. it seems that whenever i call the native call history app, this column gets updated. so my question is, how can i set that lookup_uri (or generally update that list) on my own, so that my app behaves the same as the native one? i had the same problem with the missing photo_id but i was able to set it by querying the contacs by the phone number, but i failed doing the same with the lookup column,</p>

<p>and another question. normally i can use constants for the columns i want to query, but i could not find a suiting constant for the property "lookup_uri" when i try to access it directly</p>

<pre><code>Cursor queryHistory = getActivity().getContentResolver().query(Calls.CONTENT_URI, null, null,
            null, Calls.DATE + " DESC LIMIT 10");
</code></pre>

<p>thanks in advance
