Again,the requested columns are defined, the query is made, and

the cursor iterates through the results.

Note that the managedQuery() call has become substantially more

complex. Let’s take a look at the parameters to this method in

more detail. The first parameter, Browser .BOOKMARKS_URI, is a

URI for all browser history, not only the Bookmarked items. The

second parameter defines the requested columns for the query

results. The third parameter specifies that the bookmark property

must be true. This parameter is needed in order to filter within the

query. Now the results are only browser history entries that have

been bookmarked. The fourth parameter, selection arguments, is

used only when replacement values are used, which is not used in

this case, so the value is set to null. Lastly, the fifth parameter

specifies an order to the results (most visited in descending order).

Retrieving browser history information requires setting the READ_

HISTORY_ BOOKMARKS permission.

Using the Contacts Content Provider

The Contacts database is one of the most commonly used

applications on the mobile phone. People always want phone

numbers handy for calling friends, family, coworkers, and

clients.Additionally, most phones show the identity of the caller

based on the contacts application, including nicknames, photos, or

icons.
