Directory
class Directory : BaseColumns
kotlin.Any | |
↳ | android.provider.ContactsContract.Directory |
A Directory represents a contacts corpus, e.g. Local contacts, Google Apps Global Address List or Corporate Global Address List.
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.
The most important use case for Directories is search. A Directory provider is expected to support at least Contacts.CONTENT_FILTER_URI
. If a Directory provider wants to participate in email and phone lookup functionalities, it should also implement CommonDataKinds.Email.CONTENT_FILTER_URI
and CommonDataKinds.Phone.CONTENT_FILTER_URI
.
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.
The client interacts with a directory via Contacts Provider by supplying an optional directory=
query parameter.
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:
- The URI authority is replaced with the corresponding
DIRECTORY_AUTHORITY
. - The
accountName=
andaccountType=
parameters are added or replaced using the correspondingACCOUNT_TYPE
andACCOUNT_NAME
values.
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:
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; }
The Directory table is read-only and is maintained by the Contacts Provider automatically.
It always has at least these two rows:
- The local directory. It has
Directory._ID
=Directory.DEFAULT
. This directory can be used to access locally stored contacts. The same can be achieved by omitting thedirectory=
parameter altogether. - The local invisible contacts. The corresponding directory ID is
Directory.LOCAL_INVISIBLE
.
Custom Directories are discovered by the Contacts Provider following this procedure:
- It finds all installed content providers with meta data identifying them as directory providers in AndroidManifest.xml:
<meta-data android:name="android.content.ContactDirectory" android:value="true" />
This tag should be placed inside the corresponding content provider declaration.
- Then Contacts Provider sends a
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 theACCOUNT_NAME
andACCOUNT_TYPE
columns (nulls are allowed). Since directory IDs are assigned automatically, the _ID field will not be part of the query projection. - 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.
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.
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.
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 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.
A directory row can be optionally associated with an existing account (see android.accounts.AccountManager
). If the account is later removed, the corresponding directory rows are automatically removed from the Contacts Provider.

Return TRUE if it is a remote stored directory.
notifyDirectoryChange

Properties
CONTENT_URI
static val CONTENT_URI: Uri!
The content:// style URI for this table. Requests to this URI can be performed on the UI thread because they are always unblocking.
ENTERPRISE_CONTENT_URI
static val ENTERPRISE_CONTENT_URI: Uri!
URI used for getting all directories from both the calling user and the managed profile that is linked to it.
It supports the same semantics as CONTENT_URI
and returns the same columns.
If the device has no managed profile that is linked to the calling user, it behaves in the exact same way as CONTENT_URI
.
If there is a managed profile linked to the calling user, it will return merged results from both.
Note: this query returns the calling user results before the managed profile results, and this order is not affected by the sorting parameter.
