Constants
EXTRA_BEGIN_GET_CREDENTIAL_REQUEST
public static final String EXTRA_BEGIN_GET_CREDENTIAL_REQUEST
Intent extra: The BeginGetCredentialRequest
attached with
the pendingIntent
that is invoked when the user selects an
authentication entry (intending to unlock the provider app) on the UI.
When a provider app receives a BeginGetCredentialRequest
through the
CredentialProviderService.onBeginGetCredential
call, it can construct the
BeginGetCredentialResponse
with either an authentication Action
(if the app
is locked), or a BeginGetCredentialResponse
(if the app is unlocked). In the former
case, i.e. the app is locked, user will be shown the authentication action. When selected,
the underlying PendingIntent
will be invoked which will lead the user to provider's
unlock activity. This pending intent will also contain the original
BeginGetCredentialRequest
to be retrieved and processed after the unlock
flow is complete.
After the app is unlocked, the BeginGetCredentialResponse
must be constructed
using a BeginGetCredentialResponse
, which must be set on an Intent
as an
intent extra against CredentialProviderService#EXTRA_CREDENTIALS_RESPONSE_CONTENT}.
This intent should then be set as a result through Activity.setResult(int)
before finishing the activity.
Type: BeginGetCredentialRequest
Constant Value: "android.service.credentials.extra.BEGIN_GET_CREDENTIAL_REQUEST"
EXTRA_BEGIN_GET_CREDENTIAL_RESPONSE
public static final String EXTRA_BEGIN_GET_CREDENTIAL_RESPONSE
Intent extra: The result of an authentication flow, to be set on finish of the
Activity
invoked through the PendingIntent
set on
an authentication Action
, as part of the original
BeginGetCredentialResponse
. This result should contain the actual content,
including credential entries and action entries, to be shown on the selector.
Type: BeginGetCredentialResponse
Constant Value: "android.service.credentials.extra.BEGIN_GET_CREDENTIAL_RESPONSE"
EXTRA_CREATE_CREDENTIAL_EXCEPTION
public static final String EXTRA_CREATE_CREDENTIAL_EXCEPTION
Intent extra: The failure exception set at the final stage of a create flow.
This exception is set at the finishing result of the Activity
invoked by the PendingIntent
, when a user selects the CreateEntry
that contained the PendingIntent
in question.
Type: CreateCredentialException
Constant Value: "android.service.credentials.extra.CREATE_CREDENTIAL_EXCEPTION"
EXTRA_CREATE_CREDENTIAL_REQUEST
public static final String EXTRA_CREATE_CREDENTIAL_REQUEST
Intent extra: The CreateCredentialRequest
attached with
the pendingIntent
that is invoked when the user selects a CreateEntry
returned as part of the BeginCreateCredentialResponse
Type: CreateCredentialRequest
Constant Value: "android.service.credentials.extra.CREATE_CREDENTIAL_REQUEST"
EXTRA_CREATE_CREDENTIAL_RESPONSE
public static final String EXTRA_CREATE_CREDENTIAL_RESPONSE
Intent extra: The result of a create flow operation, to be set on finish of the
Activity
invoked through the pendingIntent
set on
a CreateEntry
.
Type: CreateCredentialResponse
Constant Value: "android.service.credentials.extra.CREATE_CREDENTIAL_RESPONSE"
EXTRA_GET_CREDENTIAL_EXCEPTION
public static final String EXTRA_GET_CREDENTIAL_EXCEPTION
Intent extra: The failure exception set at the final stage of a get flow.
This exception is set at the finishing result of the Activity
invoked by the PendingIntent
, when a user selects the CredentialEntry
that contained the PendingIntent
in question.
The result must be set through Activity.setResult(int)
as an intent extra
Type: GetCredentialException
Constant Value: "android.service.credentials.extra.GET_CREDENTIAL_EXCEPTION"
EXTRA_GET_CREDENTIAL_REQUEST
public static final String EXTRA_GET_CREDENTIAL_REQUEST
Intent extra: The GetCredentialRequest
attached with
the pendingIntent
that is invoked when the user selects a CredentialEntry
returned as part of the BeginGetCredentialResponse
Type: GetCredentialRequest
Constant Value: "android.service.credentials.extra.GET_CREDENTIAL_REQUEST"
EXTRA_GET_CREDENTIAL_RESPONSE
public static final String EXTRA_GET_CREDENTIAL_RESPONSE
Intent extra: The result of a get credential flow operation, to be set on finish of the
Activity
invoked through the pendingIntent
set on
a CredentialEntry
.
Type: GetCredentialResponse
Constant Value: "android.service.credentials.extra.GET_CREDENTIAL_RESPONSE"
SERVICE_INTERFACE
public static final String SERVICE_INTERFACE
The Intent
that must be declared as handled by the service. The service must also
require the {android.Manifest.permission#BIND_CREDENTIAL_PROVIDER_SERVICE} permission
so that only the system can bind to it.
Constant Value: "android.service.credentials.CredentialProviderService"
SERVICE_META_DATA
public static final String SERVICE_META_DATA
Name under which a Credential Provider service component publishes information
about itself. This meta-data must reference an XML resource containing
an
<
tag.
For example (AndroidManifest.xml):
credential-provider
>
For example (xml/provider.xml):
Constant Value: "android.credentials.provider"

onBeginCreateCredential
public abstract void onBeginCreateCredential (BeginCreateCredentialRequest request, CancellationSignal cancellationSignal, OutcomeReceiver<BeginCreateCredentialResponse, CreateCredentialException> callback)
Called by the android system to create a credential.
Parameters | |
---|---|
request |
BeginCreateCredentialRequest : The credential creation request for the provider to handle.
This value cannot be null . |
cancellationSignal |
CancellationSignal : Signal for providers to listen to any cancellation requests from
the android system.
This value cannot be null . |
callback |
OutcomeReceiver : Object used to relay the response of the credential creation request.
This value cannot be null . |
onBeginGetCredential
public abstract void onBeginGetCredential (BeginGetCredentialRequest request, CancellationSignal cancellationSignal, OutcomeReceiver<BeginGetCredentialResponse, GetCredentialException> callback)
Called by the android system to retrieve user credentials from the connected provider service.
This API denotes a query stage request for getting user's credentials from a given
credential provider. The request contains a list of
BeginGetCredentialOption
that have parameters to be used for
populating candidate credentials, as a list of CredentialEntry
to be set
on the BeginGetCredentialResponse
. This list is then shown to the user on a
selector.
If a PendingIntent
is set on a CredentialEntry
, and the user selects that
entry, a GetCredentialRequest
with all parameters needed to get the actual
Credential
will be sent as part of the Intent
fired
through the PendingIntent
.
Parameters | |
---|---|
request |
BeginGetCredentialRequest : the request for the provider to handle
This value cannot be null . |
cancellationSignal |
CancellationSignal : signal for providers to listen to any cancellation requests from
the android system
This value cannot be null . |
callback |
OutcomeReceiver : object used to relay the response of the credentials request
This value cannot be null . |
onBind
public final IBinder onBind (Intent intent)
Return the communication channel to the service. May return null if
clients can not bind to the service. The returned
IBinder
is usually for a complex interface
that has been described using
aidl.
Note that unlike other application components, calls on to the IBinder interface returned here may not happen on the main thread of the process. More information about the main thread can be found in Processes and Threads.
Parameters | |

---|---|
IBinder |
This value cannot be null . |
onClearCredentialState
public abstract void onClearCredentialState (ClearCredentialStateRequest request, CancellationSignal cancellationSignal, OutcomeReceiver<Void, ClearCredentialStateException> callback)
Called by the android system to clear the credential state. This api isinvoked by developers after users sign out of an app, with an intention to clear any stored credential session that providers have retained. As a provider, you must clear any credential state, if maintained. For e.g. a provider may have stored an active credential session that is used to limit or rank sign-in options for future credential retrieval flows. When a user signs out of the app, such state should be cleared and an exhaustive list of credentials must be presented to the user on subsequent credential retrieval flows.
Parameters | |
---|---|
request |
ClearCredentialStateRequest : The clear credential request for the provider to handle.
This value cannot be null . |
cancellationSignal |
CancellationSignal : Signal for providers to listen to any cancellation requests from
the android system.
This value cannot be null . |
callback |
OutcomeReceiver : Object used to relay the result of the request.
This value cannot be null . |
onCreate
public void onCreate ()
Called by the system when the service is first created. Do not call this method directly. If you override this method you must call through to the superclass implementation.
