Public Methods

public static void clearToken (Context context, String token)

Clear the specified token in local cache with respect to the Context. Note that the context must be the same as that used to initialize the token in a previous call to getToken(Context, String, String) or getToken(Context, String, String, Bundle).

Parameters
context Context of the token.
token The token to clear.
Throws
GooglePlayServicesAvailabilityException
GoogleAuthException
IOException

public static List<AccountChangeEvent> getAccountChangeEvents (Context context, int eventIndex, String accountName)

Gets a list of events for the given account. The result is in reverse chronological order.

Parameters
eventIndex An event index to restrict results by. If 0 then all events will be fetched. Otherwise, events greater than this index will be fetched. Callers can store the last event index seen and use this field to limit results to only events more recent than the ones seen prior.
accountName The account name to restrict the event list to.
Throws
GoogleAuthException
IOException

public static String getAccountId (Context ctx, String accountName)

Gets a stable account id for the given account name. In the event of a missing id, user intervention may be required. In such cases, a UserRecoverableAuthException will be thrown. To initiate the user recovery workflow, clients must start the Intent returned by getIntent() for result. Upon successfully returning a client should invoke this method again to get an id.

Throws
GooglePlayServicesAvailabilityException containing the appropriate connection status error code.
UserRecoverableAuthException wrapping an Intent for initiating user intervention. The wrapped intent must be called with startActivityForResult(Intent, int).
GoogleAuthException signaling a potentially unrecoverable authentication error.
IOException signaling a potentially transient error.
IllegalStateException if the method is invoked in the main event thread.

public static String getToken (Context context, Account account, String scope, Bundle extras)

Gets a token to be consumed by Google REST APIs.

This method requires substantial network IO thus should be run off the UI thread.

Be sure to handle the UserRecoverableAuthException exception, as it is normal behavior that user interaction is required.

See Authorizing with Google for REST APIs for details.

Note that to authenticate with a backend server, you should use GoogleSignInAccount.getIdToken() or GoogleSignInAccount.getServerAuthCode(). See Authenticating with a backend server using Google Sign-In for details.

Parameters
context The Context of the caller.
account The user account that the token will be associated with.
scope A String representing the authentication scope, prefixed with "oauth2:". To specify multiple scopes, separate them with a space (for example, "oauth2:scope1 scope2 scope3").
extras A Bundle that contains additional information. For example, clients that have their own splash screens can suppress the progress dialog provided by Google Play services by setting KEY_SUPPRESS_PROGRESS_SCREEN to true in the Bundle.
Returns
  • A String that contains a valid token.
Throws
UserRecoverableAuthException Signaling that a user action is required (to provide consent, enter a password, etc.). To initiate the user action, clients must start the Intent returned by getIntent(). Upon successfully returning a client should invoke this method again to get a token.
IOException Signaling a transient error (typically network related). It is left to clients to implement a backoff/abandonment strategy appropriate to their latency requirements.
GooglePlayServicesAvailabilityException Signaling that GooglePlayServices is not available.
GoogleAuthException Signaling an unrecoverable authentication error. These errors will typically result from client errors (e.g. providing an invalid scope).
IllegalStateException If the method is invoked in the main event thread.

public static String getToken (Context context, Account account, String scope)

Throws
IOException
UserRecoverableAuthException
GoogleAuthException

UserRecoverableNotifiedException
GoogleAuthException

public static String getTokenWithNotification (Context context, Account account, String scope, Bundle extras)

Authenticates the user and returns a valid Google authentication token, or throws an Exception if there was an error while getting the token.

This method is specifically provided for background tasks. In the event of an error that needs user intervention, this method takes care of pushing relevant notification.

The exception thrown depends upon the underlying error and support for recovery. UserRecoverableNotifiedException will be thrown if the error can be resolved by user intervention and a notification has already been posted to address it. IOExceptions will be thrown if the underlying error might be solved by some intelligent retry strategy. Alternatively, GoogleAuthExceptions represent a broad class of Exceptions that cannot be recovered programmatically.

See Authorizing with Google for REST APIs for details.

Parameters
context Context associated with the desired token.
account Authenticating user account.
scope String representing the authentication scope. To specify multiple scopes, separate them with a space (for example, "oauth2:scope1 scope2 scope3").
extras Bundle containing additional information that may be relevant to the authentication scope.
Returns
  • String containing a valid token.
Throws
UserRecoverableNotifiedException if a user addressable error occurred and a notification was pushed.
GoogleAuthException signaling a potentially unrecoverable authentication error.
IOException signaling a potentially transient error.
IllegalStateException if the method is invoked in the main event thread.

public static String getTokenWithNotification (Context context, String accountName, String scope, Bundle extras, Intent callback)

This method was deprecated.
Use getTokenWithNotification(Context, Account, String, Bundle, Intent) instead.

Throws
IOException
UserRecoverableNotifiedException
GoogleAuthException

public static String getTokenWithNotification (Context context, Account account, String scope, Bundle extras, String authority, Bundle syncBundle)

Authenticates the user and returns a valid Google authentication token, or throws an Exception if there was an error while getting the token.

This method is specifically provided for sync adaptors. In the event of an error that needs user intervention, this method takes care of pushing relevant notification. After the user addresses the notification, a sync request will be kicked off using the given params. If the user cancels then the sync is not fired.

The exception thrown depends upon the underlying error and support for recovery. UserRecoverableNotifiedException will be thrown if the error can be resolved by user intervention and a notification has already been posted to address it. IOExceptions will be thrown if the underlying error might be solved by some intelligent retry strategy. Alternatively, GoogleAuthExceptions represent a broad class of Exceptions that cannot be recovered programmatically.

Parameters
context Context associated with the desired token.
account Authenticating user account.
scope String representing the authentication scope. To specify multiple scopes, separate them with a space (for example, "oauth2:scope1 scope2 scope3").
extras Bundle containing additional information that may be relevant to the authentication scope.
authority Authority for firing a sync request. Must not be empty or null.
syncBundle extras for firing a sync request. This bundle must pass ContentResolver.validateSyncExtrasBundle(). If no extras are needed can a null value can be passed.
Returns
  • String containing a valid token.
Throws
UserRecoverableNotifiedException if a user addressable error occurred and a notification was pushed.
GoogleAuthException signaling a potentially unrecoverable authentication error.

UserRecoverableNotifiedException
GoogleAuthException

public static String getTokenWithNotification (Context context, Account account, String scope, Bundle extras, Intent callback)

Authenticates the user and returns a valid Google authentication token, or throws an Exception if there was an error while getting the token.

This method is specifically provided for background tasks. In the event of an error that needs user intervention, this method takes care of pushing relevant notification. After the user addresses the notification, the callback is broadcasted. If the user cancels then the callback is not fired.

The exception thrown depends upon the underlying error and support for recovery. UserRecoverableNotifiedException will be thrown if the error can be resolved by user intervention and a notification has already been posted to address it. IOExceptions will be thrown if the underlying error might be solved by some intelligent retry strategy. Alternatively, GoogleAuthExceptions represent a broad class of Exceptions that cannot be recovered programmatically.

See Authorizing with Google for REST APIs for details.

Parameters
context Context associated with the desired token.
account Authenticating user account.
scope String representing the authentication scope. To specify multiple scopes, separate them with a space (for example, "oauth2:scope1 scope2 scope3").
extras Bundle containing additional information that may be relevant to the authentication scope.
callback A broadcast intent with a valid receiver that has been exported for other apps to send broadcasts to it. This intent must be serializable using toUri(Intent.URI_INTENT_SCHEME) and Intent.parseUri(intentUri, Intent.URI_INTENT_SCHEME). Cannot be null.
Returns
  • String containing a valid token.
Throws
UserRecoverableNotifiedException if a user addressable error occurred and a notification was pushed.

Like removeAccount(Account, AccountManagerCallback, Handler) but where the permission checks are not enforced for Google applications, device owner or profile owner. It is also a heavily stripped down version of the original method.

This method is NOT safe to call from UI thread. It will fail and throw exceptions.

See DevicePolicyManager for definition of device owner and profile owner.

Parameters
context Context of the caller.
account The account to remove.
Returns
Throws
GoogleAuthException
IOException
