You can see exactly how the data is stored by querying the contacts database. See chapter 5 if you need a review of using the sqlite3 tool, with which we’ll query the tables that were created when adding the initial three contacts. In figure 15.4, we connect to the sqlite database stored at /data/data/com.android.providers.contacts/databases/contacts2.db. Querying the data table returns the individual pieces of contact information on the device. The contacts table includes individual contact entities. Joining these two tables results in the information visible in the Contacts application.
