/**
 * <p>
 * The contract between the contacts provider and applications. Contains
 * definitions for the supported URIs and columns. These APIs supersede
 * {@link Contacts}.
 * </p>
 * <h3>Overview</h3>
 * <p>
 * ContactsContract defines an extensible database of contact-related
 * information. Contact information is stored in a three-tier data model:
 * </p>
 * <ul>
 * <li>
 * A row in the {@link Data} table can store any kind of personal data, such
 * as a phone number or email addresses.  The set of data kinds that can be
 * stored in this table is open-ended. There is a predefined set of common
 * kinds, but any application can add its own data kinds.
 * </li>
 * <li>
 * A row in the {@link RawContacts} table represents a set of data describing a
 * person and associated with a single account (for example, one of the user's
 * Gmail accounts).
 * </li>
 * <li>
 * A row in the {@link Contacts} table represents an aggregate of one or more
 * RawContacts presumably describing the same person.  When data in or associated with
 * the RawContacts table is changed, the affected aggregate contacts are updated as
 * necessary.
 * </li>
 * </ul>
 * <p>
 * Other tables include:
 * </p>
 * <ul>
 * <li>
 * {@link Groups}, which contains information about raw contact groups
 * such as Gmail contact groups.  The
 * current API does not support the notion of groups spanning multiple accounts.
 * </li>
 * <li>
 * {@link StatusUpdates}, which contains social status updates including IM
 * availability.
 * </li>
 * <li>
 * {@link AggregationExceptions}, which is used for manual aggregation and
 * disaggregation of raw contacts
 * </li>
 * <li>
 * {@link Settings}, which contains visibility and sync settings for accounts
 * and groups.
 * </li>
 * <li>
 * {@link SyncState}, which contains free-form data maintained on behalf of sync
 * adapters
 * </li>
 * <li>
 * {@link PhoneLookup}, which is used for quick caller-ID lookup</li>
 * </ul>

    /**
     * A Directory represents a contacts corpus, e.g. Local contacts,

     * <p>
     * A Directory is implemented as a content provider with its unique authority and
     * the same API as the main Contacts Provider.  However, there is no expectation that
     * every directory provider will implement this Contract in its entirety.  If a
     * directory provider does not have an implementation for a specific request, it
     * should throw an UnsupportedOperationException.
     * </p>
     * <p>
     * The most important use case for Directories is search.  A Directory provider is
     * expected to support at least {@link ContactsContract.Contacts#CONTENT_FILTER_URI
     * Contacts.CONTENT_FILTER_URI}.  If a Directory provider wants to participate
     * in email and phone lookup functionalities, it should also implement
     * {@link CommonDataKinds.Email#CONTENT_FILTER_URI CommonDataKinds.Email.CONTENT_FILTER_URI}
     * and
     * {@link CommonDataKinds.Phone#CONTENT_FILTER_URI CommonDataKinds.Phone.CONTENT_FILTER_URI}.
     * </p>
     * <p>
     * A directory provider should return NULL for every projection field it does not
     * recognize, rather than throwing an exception.  This way it will not be broken
     * if ContactsContract is extended with new fields in the future.
     * </p>
     * <p>
     * The client interacts with a directory via Contacts Provider by supplying an
     * optional {@code directory=} query parameter.
     * <p>
     * <p>
     * When the Contacts Provider receives the request, it transforms the URI and forwards
     * the request to the corresponding directory content provider.
     * The URI is transformed in the following fashion:
     * <ul>
     * <li>The URI authority is replaced with the corresponding {@link #DIRECTORY_AUTHORITY}.</li>
     * <li>The {@code accountName=} and {@code accountType=} parameters are added or
     * replaced using the corresponding {@link #ACCOUNT_TYPE} and {@link #ACCOUNT_NAME} values.</li>
     * </ul>
     * </p>
     * <p>
     * Clients should send directory requests to Contacts Provider and let it
     * forward them to the respective providers rather than constructing
     * directory provider URIs by themselves. This level of indirection allows
     * Contacts Provider to implement additional system-level features and
     * optimizations. Access to Contacts Provider is protected by the
     * READ_CONTACTS permission, but access to the directory provider is protected by
     * BIND_DIRECTORY_SEARCH. This permission was introduced at the API level 17, for previous
     * platform versions the provider should perform the following check to make sure the call
     * is coming from the ContactsProvider:
     * <pre>
     * private boolean isCallerAllowed() {
     *   PackageManager pm = getContext().getPackageManager();
     *   for (String packageName: pm.getPackagesForUid(Binder.getCallingUid())) {
     *     if (packageName.equals("com.android.providers.contacts")) {
     *       return true;
     *     }
     *   }
     *   return false;
     * }
     * </pre>
     * </p>
     * <p>
     * The Directory table is read-only and is maintained by the Contacts Provider
     * automatically.
     * </p>
     * <p>It always has at least these two rows:
     * <ul>
     * <li>
     * The local directory. It has {@link Directory#_ID Directory._ID} =
     * {@link Directory#DEFAULT Directory.DEFAULT}. This directory can be used to access locally
     * stored contacts. The same can be achieved by omitting the {@code directory=}
     * parameter altogether.
     * </li>
     * <li>
     * The local invisible contacts. The corresponding directory ID is
     * {@link Directory#LOCAL_INVISIBLE Directory.LOCAL_INVISIBLE}.
     * </li>
     * </ul>
     * </p>
     * <p>Custom Directories are discovered by the Contacts Provider following this procedure:
     * <ul>
     * <li>It finds all installed content providers with meta data identifying them
     * as directory providers in AndroidManifest.xml:
     * <code>
     * &lt;meta-data android:name="android.content.ContactDirectory"
     *               android:value="true" /&gt;
     * </code>
     * <p>
     * This tag should be placed inside the corresponding content provider declaration.
     * </p>
     * </li>
     * <li>
     * Then Contacts Provider sends a {@link Directory#CONTENT_URI Directory.CONTENT_URI}
     * query to each of the directory authorities.  A directory provider must implement
     * this query and return a list of directories.  Each directory returned by
     * the provider must have a unique combination for the {@link #ACCOUNT_NAME} and
     * {@link #ACCOUNT_TYPE} columns (nulls are allowed).  Since directory IDs are assigned
     * automatically, the _ID field will not be part of the query projection.
     * </li>
     * <li>Contacts Provider compiles directory lists received from all directory
     * providers into one, assigns each individual directory a globally unique ID and
     * stores all directory records in the Directory table.
     * </li>
     * </ul>
     * </p>
     * <p>Contacts Provider automatically interrogates newly installed or replaced packages.
     * Thus simply installing a package containing a directory provider is sufficient
     * to have that provider registered.  A package supplying a directory provider does
     * not have to contain launchable activities.
     * </p>
     * <p>
     * Every row in the Directory table is automatically associated with the corresponding package
     * (apk).  If the package is later uninstalled, all corresponding directory rows
     * are automatically removed from the Contacts Provider.
     * </p>
     * <p>
     * When the list of directories handled by a directory provider changes
     * (for instance when the user adds a new Directory account), the directory provider
     * should call {@link #notifyDirectoryChange} to notify the Contacts Provider of the change.
     * In response, the Contacts Provider will requery the directory provider to obtain the
     * new list of directories.
     * </p>
     * <p>
     * A directory row can be optionally associated with an existing account
     * (see {@link android.accounts.AccountManager}). If the account is later removed,
     * the corresponding directory rows are automatically removed from the Contacts Provider.

     * <h3>Aggregation</h3>
     * <p>
     * As soon as a raw contact is inserted or whenever its constituent data

     * </p>
     * <p>
     * Changes to the structured name, organization, phone number, email address,
     * or nickname trigger a re-aggregation.
     * </p>
     * <p>
     * See also {@link AggregationExceptions} for a mechanism to control
     * aggregation programmatically.
     * </p>
     *
     * <h3>Operations</h3>
     * <dl>
     * <dt><b>Insert</b></dt>
     * <dd>
     * <p>
     * Raw contacts can be inserted incrementally or in a batch.
     * The incremental method is more traditional but less efficient.
     * It should be used
     * only if no {@link Data} values are available at the time the raw contact is created:
     * <pre>
     * ContentValues values = new ContentValues();
     * values.put(RawContacts.ACCOUNT_TYPE, accountType);
     * values.put(RawContacts.ACCOUNT_NAME, accountName);
     * Uri rawContactUri = getContentResolver().insert(RawContacts.CONTENT_URI, values);
     * long rawContactId = ContentUris.parseId(rawContactUri);
     * </pre>
     * </p>
     * <p>
     * Once {@link Data} values become available, insert those.
     * For example, here's how you would insert a name:
     *
     * <pre>
     * values.clear();
     * values.put(Data.RAW_CONTACT_ID, rawContactId);
     * values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
     * values.put(StructuredName.DISPLAY_NAME, &quot;Mike Sullivan&quot;);
     * getContentResolver().insert(Data.CONTENT_URI, values);
     * </pre>
     * </p>
     * <p>
     * The batch method is by far preferred.  It inserts the raw contact and its
     * constituent data rows in a single database transaction
     * and causes at most one aggregation pass.
     * <pre>
     * ArrayList&lt;ContentProviderOperation&gt; ops =
     *          new ArrayList&lt;ContentProviderOperation&gt;();
     * ...
     * int rawContactInsertIndex = ops.size();
     * ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
     *          .withValue(RawContacts.ACCOUNT_TYPE, accountType)
     *          .withValue(RawContacts.ACCOUNT_NAME, accountName)
     *          .build());
     *
     * ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
     *          .withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex)
     *          .withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE)
     *          .withValue(StructuredName.DISPLAY_NAME, &quot;Mike Sullivan&quot;)
     *          .build());
     *
     * getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
     * </pre>
     * </p>
     * <p>
     * Note the use of {@link ContentProviderOperation.Builder#withValueBackReference(String, int)}
     * to refer to the as-yet-unknown index value of the raw contact inserted in the
     * first operation.
     * </p>
     *
     * <dt><b>Update</b></dt>
     * <dd><p>
     * Raw contacts can be updated incrementally or in a batch.
     * Batch mode should be used whenever possible.
     * The procedures and considerations are analogous to those documented above for inserts.
     * </p></dd>
     * <dt><b>Delete</b></dt>
     * <dd><p>When a raw contact is deleted, all of its Data rows as well as StatusUpdates,
     * AggregationExceptions, PhoneLookup rows are deleted automatically. When all raw
     * contacts associated with a {@link Contacts} row are deleted, the {@link Contacts} row
     * itself is also deleted automatically.
     * </p>
     * <p>
     * The invocation of {@code resolver.delete(...)}, does not immediately delete
     * a raw contacts row.
     * Instead, it sets the {@link #DELETED} flag on the raw contact and
     * removes the raw contact from its aggregate contact.
     * The sync adapter then deletes the raw contact from the server and
     * finalizes phone-side deletion by calling {@code resolver.delete(...)}
     * again and passing the {@link ContactsContract#CALLER_IS_SYNCADAPTER} query parameter.<p>
     * <p>Some sync adapters are read-only, meaning that they only sync server-side
     * changes to the phone, but not the reverse.  If one of those raw contacts
     * is marked for deletion, it will remain on the phone.  However it will be
     * effectively invisible, because it will not be part of any aggregate contact.
     * </dd>
     *
     * <dt><b>Query</b></dt>
     * <dd>
     * <p>
     * It is easy to find all raw contacts in a Contact:
     * <pre>
     * Cursor c = getContentResolver().query(RawContacts.CONTENT_URI,
     *          new String[]{RawContacts._ID},
     *          RawContacts.CONTACT_ID + "=?",
     *          new String[]{String.valueOf(contactId)}, null);
     * </pre>
     * </p>
     * <p>
     * To find raw contacts within a specific account,
     * you can either put the account name and type in the selection or pass them as query
     * parameters.  The latter approach is preferable, especially when you can reuse the
     * URI:
     * <pre>
     * Uri rawContactUri = RawContacts.CONTENT_URI.buildUpon()
     *          .appendQueryParameter(RawContacts.ACCOUNT_NAME, accountName)
     *          .appendQueryParameter(RawContacts.ACCOUNT_TYPE, accountType)
     *          .build();
     * Cursor c1 = getContentResolver().query(rawContactUri,
     *          RawContacts.STARRED + "&lt;&gt;0", null, null, null);
     * ...
     * Cursor c2 = getContentResolver().query(rawContactUri,
     *          RawContacts.DELETED + "&lt;&gt;0", null, null, null);
     * </pre>
     * </p>
     * <p>The best way to read a raw contact along with all the data associated with it is
     * by using the {@link Entity} directory. If the raw contact has data rows,
     * the Entity cursor will contain a row for each data row.  If the raw contact has no
     * data rows, the cursor will still contain one row with the raw contact-level information.
     * <pre>
     * Uri rawContactUri = ContentUris.withAppendedId(RawContacts.CONTENT_URI, rawContactId);
     * Uri entityUri = Uri.withAppendedPath(rawContactUri, Entity.CONTENT_DIRECTORY);
     * Cursor c = getContentResolver().query(entityUri,
     *          new String[]{RawContacts.SOURCE_ID, Entity.DATA_ID, Entity.MIMETYPE, Entity.DATA1},
     *          null, null, null);
     * try {
     *     while (c.moveToNext()) {
     *         String sourceId = c.getString(0);
     *         if (!c.isNull(1)) {
     *             String mimeType = c.getString(2);
     *             String data = c.getString(3);
     *             ...
     *         }

     * {@link CommonDataKinds.Email Email.CONTENT_ITEM_TYPE}, then {@link #DATA1}
     * stores the email address.
     * Sync adapters and applications can introduce their own data kinds.
     * </p>
     * <p>
     * ContactsContract defines a small number of pre-defined data kinds, e.g.
     * {@link CommonDataKinds.Phone}, {@link CommonDataKinds.Email} etc. As a
     * convenience, these classes define data kind specific aliases for DATA1 etc.
     * For example, {@link CommonDataKinds.Phone Phone.NUMBER} is the same as
     * {@link ContactsContract.Data Data.DATA1}.
     * </p>
     * <p>
     * {@link #DATA1} is an indexed column and should be used for the data element that is
     * expected to be most frequently used in query selections. For example, in the
     * case of a row representing email addresses {@link #DATA1} should probably
     * be used for the email address itself, while {@link #DATA2} etc can be
     * used for auxiliary information like type of email address.
     * <p>
     * <p>
     * By convention, {@link #DATA15} is used for storing BLOBs (binary data).
     * </p>
     * <p>
     * The sync adapter for a given account type must correctly handle every data type
     * used in the corresponding raw contacts.  Otherwise it could result in lost or
     * corrupted data.
     * </p>
     * <p>
     * Similarly, you should refrain from introducing new kinds of data for an other
     * party's account types. For example, if you add a data row for
     * "favorite song" to a raw contact owned by a Google account, it will not
     * get synced to the server, because the Google sync adapter does not know
     * how to handle this data kind. Thus new data kinds are typically
     * introduced along with new account types, i.e. new sync adapters.
     * </p>
     * <h3>Batch operations</h3>
     * <p>
     * Data rows can be inserted/updated/deleted using the traditional
     * {@link ContentResolver#insert}, {@link ContentResolver#update} and
     * {@link ContentResolver#delete} methods, however the newer mechanism based
     * on a batch of {@link ContentProviderOperation} will prove to be a better
     * choice in almost all cases. All operations in a batch are executed in a
     * single transaction, which ensures that the phone-side and server-side
     * state of a raw contact are always consistent. Also, the batch-based
     * approach is far more efficient: not only are the database operations
     * faster when executed in a single transaction, but also sending a batch of
     * commands to the content provider saves a lot of time on context switching
     * between your process and the process in which the content provider runs.
     * </p>
     * <p>
     * The flip side of using batched operations is that a large batch may lock
     * up the database for a long time preventing other applications from
     * accessing data and potentially causing ANRs ("Application Not Responding"
     * dialogs.)
     * </p>
     * <p>
     * To avoid such lockups of the database, make sure to insert "yield points"
     * in the batch. A yield point indicates to the content provider that before
     * executing the next operation it can commit the changes that have already
     * been made, yield to other requests, open another transaction and continue
     * processing operations. A yield point will not automatically commit the
     * transaction, but only if there is another request waiting on the
     * database. Normally a sync adapter should insert a yield point at the
     * beginning of each raw contact operation sequence in the batch. See
     * {@link ContentProviderOperation.Builder#withYieldAllowed(boolean)}.
     * </p>
     * <h3>Operations</h3>
     * <dl>
     * <dt><b>Insert</b></dt>
     * <dd>
     * <p>
     * An individual data row can be inserted using the traditional
     * {@link ContentResolver#insert(Uri, ContentValues)} method. Multiple rows
     * should always be inserted as a batch.
     * </p>
     * <p>
     * An example of a traditional insert:
     * <pre>
     * ContentValues values = new ContentValues();
     * values.put(Data.RAW_CONTACT_ID, rawContactId);
     * values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
     * values.put(Phone.NUMBER, "1-800-GOOG-411");
     * values.put(Phone.TYPE, Phone.TYPE_CUSTOM);
     * values.put(Phone.LABEL, "free directory assistance");
     * Uri dataUri = getContentResolver().insert(Data.CONTENT_URI, values);
     * </pre>
     * <p>
     * The same done using ContentProviderOperations:
     * <pre>
     * ArrayList&lt;ContentProviderOperation&gt; ops =
     *          new ArrayList&lt;ContentProviderOperation&gt;();
     *
     * ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
     *          .withValue(Data.RAW_CONTACT_ID, rawContactId)
     *          .withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE)
     *          .withValue(Phone.NUMBER, "1-800-GOOG-411")
     *          .withValue(Phone.TYPE, Phone.TYPE_CUSTOM)
     *          .withValue(Phone.LABEL, "free directory assistance")
     *          .build());
     * getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
     * </pre>
     * </p>
     * <dt><b>Update</b></dt>
     * <dd>
     * <p>
     * Just as with insert, update can be done incrementally or as a batch,
     * the batch mode being the preferred method:
     * <pre>
     * ArrayList&lt;ContentProviderOperation&gt; ops =
     *          new ArrayList&lt;ContentProviderOperation&gt;();
     *
     * ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
     *          .withSelection(Data._ID + "=?", new String[]{String.valueOf(dataId)})
     *          .withValue(Email.DATA, "somebody@android.com")
     *          .build());
     * getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
     * </pre>
     * </p>
     * </dd>
     * <dt><b>Delete</b></dt>
     * <dd>
     * <p>
     * Just as with insert and update, deletion can be done either using the
     * {@link ContentResolver#delete} method or using a ContentProviderOperation:
     * <pre>
     * ArrayList&lt;ContentProviderOperation&gt; ops =
     *          new ArrayList&lt;ContentProviderOperation&gt;();
     *
     * ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI)
     *          .withSelection(Data._ID + "=?", new String[]{String.valueOf(dataId)})
     *          .build());
     * getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

         * <p>
         * To allow the Voice Assistant to help users with contacts disambiguation, the messaging
         * app may choose to integrate with the Contacts Provider. You will need to specify a new
         * MIME type in order to store your app’s unique contact IDs and optional human readable
         * labels in the Data table. The Voice Assistant needs to know this MIME type and {@link
         * RawContacts#ACCOUNT_TYPE} that you are using in order to provide the smooth contact
         * disambiguation user experience. The following convention should be met when performing
         * such integration:
         * <ul>
         * <li>This activity should have a string meta-data field associated with it, {@link
         * #METADATA_ACCOUNT_TYPE}, which defines {@link RawContacts#ACCOUNT_TYPE} for your Contacts
         * Provider implementation. The account type should be globally unique, for example you can
         * use your app package name as the account type.</li>
         * <li>This activity should have a string meta-data field associated with it, {@link
         * #METADATA_MIMETYPE}, which defines {@link DataColumns#MIMETYPE} for your Contacts
         * Provider implementation. For example, you can use
         * "vnd.android.cursor.item/vnd.{$app_package_name}.profile" as MIME type.</li>
         * <li>When filling Data table row for METADATA_MIMETYPE, column {@link DataColumns#DATA1}
         * should store the unique contact ID as understood by the app. This value will be used in
         * the {@link #EXTRA_RECIPIENT_CONTACT_CHAT_ID}.</li>
         * <li>Optionally, when filling Data table row for METADATA_MIMETYPE, column {@link
         * DataColumns#DATA3} could store a human readable label for the ID. For example it could be
         * phone number or human readable username/user_id like "a_super_cool_user_name". This label
         * may be shown below the Contact Name by the Voice Assistant as the user completes the
         * voice action. If DATA3 is empty, the ID in DATA1 may be shown instead.</li>
         * <li><em>Note: Do not use DATA3 to store the Contact Name. The Voice Assistant will
         * already get the Contact Name from the RawContact’s display_name.</em></li>
         * <li><em>Note: Some apps may choose to use phone number as the unique contact ID in DATA1.
         * If this applies to you and you’d like phone number to be shown below the Contact Name by
         * the Voice Assistant, then you may choose to leave DATA3 empty.</em></li>
         * <li><em>Note: If your app also uses DATA3 to display contact details in the Contacts App,
         * make sure it does not include prefix text such as "Message +<phone>" or "Free Message
         * +<phone>", etc. If you must show the prefix text in the Contacts App, please use a
         * different DATA# column, and update your contacts.xml to point to this new column. </em>

         * either METADATA_ACCOUNT_TYPE or METADATA_MIMETYPE field is missing), Voice Assistant
         * will use existing phone number entries as contact ID's for such app.
         * <p>
         * Input: {@link android.content.Intent#getType} is the MIME type of the data being sent.
         * The intent sender will always put the concrete mime type in the intent type, like
         * "text/plain" or "audio/wav" for example. If the MIME type is "text/plain", message to
         * sent will be provided via {@link android.content.Intent#EXTRA_TEXT} as a styled
         * CharSequence. Otherwise, the message content will be supplied through {@link
         * android.content.Intent#setClipData(ClipData)} as a content provider URI(s). In the latter
         * case, EXTRA_TEXT could still be supplied optionally; for example, for audio messages
         * ClipData will contain URI of a recording and EXTRA_TEXT could contain the text
         * transcription of this recording.
         * <p>
         * The message can have n recipients. The n-th recipient of the message will be provided as
