AccountManager

Kotlin |Java

public class AccountManager
extends Object

java.lang.Object
↳	android.accounts.AccountManager

This class provides access to a centralized registry of the user's online accounts. The user enters credentials (username and password) once per account, granting applications access to online resources with "one-click" approval.

Different online services have different ways of handling accounts and authentication, so the account manager uses pluggable authenticator modules for different account types. Authenticators (which may be written by third parties) handle the actual details of validating account credentials and storing account information. For example, Google, Facebook, and Microsoft Exchange each have their own authenticator.

Many servers support some notion of an authentication token, which can be used to authenticate a request to the server without sending the user's actual password. (Auth tokens are normally created with a separate request which does include the user's credentials.) AccountManager can generate auth tokens for applications, so the application doesn't need to handle passwords directly. Auth tokens are normally reusable and cached by AccountManager, but must be refreshed periodically. It's the responsibility of applications to invalidate auth tokens when they stop working so the AccountManager knows it needs to regenerate them.

Applications accessing a server normally go through these steps:

Get an instance of AccountManager using get(android.content.Context).
List the available accounts using getAccountsByType(String) or getAccountsByTypeAndFeatures(String, String, AccountManagerCallback, Handler). Normally applications will only be interested in accounts with one particular type, which identifies the authenticator. Account features are used to identify particular account subtypes and capabilities. Both the account type and features are authenticator-specific strings, and must be known by the application in coordination with its preferred authenticators.
Select one or more of the available accounts, possibly by asking the user for their preference. If no suitable accounts are available, addAccount(String, String, String, Bundle, Activity, AccountManagerCallback, Handler) may be called to prompt the user to create an account of the appropriate type.
Important: If the application is using a previously remembered account selection, it must make sure the account is still in the list of accounts returned by getAccountsByType(String). Requesting an auth token for an account no longer on the device results in an undefined failure.
Request an auth token for the selected account(s) using one of the getAuthToken(Account, String, Bundle, Activity, AccountManagerCallback, Handler) methods or related helpers. Refer to the description of each method for exact usage and error handling details.
Make the request using the auth token. The form of the auth token, the format of the request, and the protocol used are all specific to the service you are accessing. The application may use whatever network and protocol libraries are useful.
Important: If the request fails with an authentication error, it could be that a cached auth token is stale and no longer honored by the server. The application must call invalidateAuthToken(String, String) to remove the token from the cache, otherwise requests will continue failing! After invalidating the auth token, immediately go back to the "Request an auth token" step above. If the process fails the second time, then it can be treated as a "genuine" authentication failure and the user notified or other appropriate actions taken.

Some AccountManager methods may need to interact with the user to prompt for credentials, present options, or ask the user to add an account. The caller may choose whether to allow AccountManager to directly launch the necessary user interface and wait for the user, or to return an Intent which the caller may use to launch the interface, or (in some cases) to install a notification which the user can select at any time to launch the interface. To have AccountManager launch the interface directly, the caller must supply the current foreground Activity context.

Many AccountManager methods take AccountManagerCallback and Handler as parameters. These methods return immediately and run asynchronously. If a callback is provided then AccountManagerCallback.run will be invoked on the Handler's thread when the request completes, successfully or not. The result is retrieved by calling AccountManagerFuture.getResult() on the AccountManagerFuture returned by the method (and also passed to the callback). This method waits for the operation to complete (if necessary) and either returns the result or throws an exception if an error occurred during the operation. To make the request synchronously, call AccountManagerFuture.getResult() immediately on receiving the future from the method; no callback need be supplied.

Requests which may block, including AccountManagerFuture.getResult(), must never be called on the application's main event thread. These operations throw IllegalStateException if they are used on the main thread.

addAccount

Added in API level 5

public AccountManagerFuture<Bundle> addAccount (String accountType, 
                String authTokenType, 
                String[] requiredFeatures, 
                Bundle addAccountOptions, 
                Activity activity, 
                AccountManagerCallback<Bundle> callback, 
                Handler handler)

Asks the user to add an account of a specified type. The authenticator for this account type processes this request with the appropriate user interface. If the user does elect to create a new account, the account name is returned.

This method may be called from any thread, but the returned AccountManagerFuture must not be used on the main thread.

NOTE: If targeting your app to work on API level 22 and before, MANAGE_ACCOUNTS permission is needed for those platforms. See docs for this function in API level 22.
Requires android.Manifest.permission.MANAGE_ACCOUNTS

Parameters
`accountType`	`String`: The type of account to add; must not be null
`authTokenType`	`String`: The type of auth token (see `getAuthToken(Account, String, Bundle, Activity, AccountManagerCallback, Handler)`) this account will need to be able to generate, null for none
`requiredFeatures`	`String`: The features (see `hasFeatures(Account, String, AccountManagerCallback, Handler)`) this account must have, null for none
`addAccountOptions`	`Bundle`: Authenticator-specific options for the request, may be null or empty
`activity`	`Activity`: The `Activity` context to use for launching a new authenticator-defined sub-Activity to prompt the user to create an account; used only to call startActivity(); if null, the prompt will not be launched directly, but the necessary `Intent` will be returned to the caller instead
`callback`	`AccountManagerCallback`: Callback to invoke when the request completes, null for no callback
`handler`	`Handler`: `Handler` identifying the callback thread, null for the main thread

Returns

Returns
`AccountManagerFuture<Bundle>`	An `AccountManagerFuture` which resolves to a Bundle with these fields if activity was specified and an account was created: `KEY_ACCOUNT_NAME` - the name of the account created `KEY_ACCOUNT_TYPE` - the type of the account If no activity was specified, the returned Bundle contains only `KEY_INTENT` with the `Intent` needed to launch the actual account creation process. If an error occurred, `AccountManagerFuture.getResult()` throws: `AuthenticatorException` if no authenticator was registered for this account type or the authenticator failed to respond `OperationCanceledException` if the operation was canceled for any reason, including the user canceling the creation process or adding accounts (of this type) has been disabled by policy `IOException` if the authenticator experienced an I/O problem creating a new account, usually because of network trouble

AuthenticatorException if no authenticator was registered for this account type or the authenticator failed to respond
OperationCanceledException if the operation was canceled for any reason, including the user canceling the creation process or adding accounts (of this type) has been disabled by policy
IOException if the authenticator experienced an I/O problem creating a new account, usually because of network trouble

addAccountExplicitly

Added in API level 5

public boolean addAccountExplicitly (Account account, 
                String password, 
                Bundle userdata)

Adds an account directly to the AccountManager. Normally used by sign-up wizards associated with authenticators, not directly by applications.

Calling this method does not update the last authenticated timestamp, referred by KEY_LAST_AUTHENTICATED_TIME. To update it, call notifyAccountAuthenticated(android.accounts.Account) after getting success. However, if this method is called when it is triggered by addAccount() or addAccountAsUser() or similar functions, then there is no need to update timestamp manually as it is updated automatically by framework on successful completion of the mentioned functions.

It is safe to call this method from the main thread.

This method requires the caller to have a signature match with the authenticator that owns the specified account.

NOTE: If targeting your app to work on API level 22 and before, AUTHENTICATE_ACCOUNTS permission is needed for those platforms. See docs for this function in API level 22.
Requires android.Manifest.permission.AUTHENTICATE_ACCOUNTS

Parameters
`account`	`Account`: The `Account` to add
`password`	`String`: The password to associate with the account, null for none
`userdata`	`Bundle`: String values to use for the account's userdata, null for none

Returns
`boolean`	True if the account was successfully added, false if the account already exists, the account is null, the user is locked, or another error occurs.

addAccountExplicitly

Added in API level 26

public boolean addAccountExplicitly (Account account, 
                String password, 
                Bundle extras, 
                Map<String, Integer> visibility)

Adds an account directly to the AccountManager. Additionally it specifies Account visibility for given list of packages.

Normally used by sign-up wizards associated with authenticators, not directly by applications.

It is safe to call this method from the main thread.

This method requires the caller to have a signature match with the authenticator that owns the specified account.

Parameters
`account`	`Account`: The `Account` to add
`password`	`String`: The password to associate with the account, null for none
`extras`	`Bundle`: String values to use for the account's userdata, null for none
`visibility`	`Map`: Map from packageName to visibility values which will be set before account is added. See `getAccountVisibility(Account, String)` for possible values. Declaring package visibility needs for package names in the map is needed, if the caller is targeting API level 34 and above.

Returns
`boolean`	True if the account was successfully added, false if the account already exists, the account is null, or another error occurs.

addOnAccountsUpdatedListener

Added in API level 26

public void addOnAccountsUpdatedListener (OnAccountsUpdateListener listener, 
                Handler handler, 
                boolean updateImmediately, 
                String[] accountTypes)

Adds an OnAccountsUpdateListener to this instance of the AccountManager. This listener will be notified whenever user or AbstractAccountAuthenticator made changes to accounts of given types related to the caller - either list of accounts returned by getAccounts() was changed, or new account was added for which user can grant access to the caller.

As long as this listener is present, the AccountManager instance will not be garbage-collected, and neither will the Context used to retrieve it, which may be a large Activity instance. To avoid memory leaks, you must remove this listener before then. Normally listeners are added in an Activity or Service's Activity.onCreate and removed in Activity.onDestroy.

It is safe to call this method from the main thread.

Parameters
`listener`	`OnAccountsUpdateListener`: The listener to send notifications to
`handler`	`Handler`: `Handler` identifying the thread to use for notifications, null for the main thread
`updateImmediately`	`boolean`: If true, the listener will be invoked (on the handler thread) right away with the current account list
`accountTypes`	`String`: If set, only changes to accounts of given types will be reported.

Throws
`IllegalArgumentException`	if listener is null
`IllegalStateException`	if listener was already added

addOnAccountsUpdatedListener

Added in API level 5

public void addOnAccountsUpdatedListener (OnAccountsUpdateListener listener, 
                Handler handler, 
                boolean updateImmediately)

Adds an OnAccountsUpdateListener to this instance of the AccountManager. This listener will be notified whenever user or AbstractAccountAuthenticator made changes to accounts of any type related to the caller. This method is equivalent to addOnAccountsUpdatedListener(listener, handler, updateImmediately, null)
Requires Manifest.permission.GET_ACCOUNTS

Parameters
`listener`	`OnAccountsUpdateListener`
`handler`	`Handler`
`updateImmediately`	`boolean`

addOnAccountsUpdatedListener(OnAccountsUpdateListener, Handler, boolean, String[])

blockingGetAuthToken

Added in API level 5

public String blockingGetAuthToken (Account account, 
                String authTokenType, 
                boolean notifyAuthFailure)

This convenience helper synchronously gets an auth token with getAuthToken(android.accounts.Account, java.lang.String, boolean, android.accounts.AccountManagerCallback, android.os.Handler).

This method may block while a network request completes, and must never be made from the main thread.

NOTE: If targeting your app to work on API level 22 and before, USE_CREDENTIALS permission is needed for those platforms. See docs for this function in API level 22.
Requires android.Manifest.permission.USE_CREDENTIALS

Parameters
`account`	`Account`: The account to fetch an auth token for
`authTokenType`	`String`: The auth token type, see `getAuthToken()`
`notifyAuthFailure`	`boolean`: If true, display a notification and return null if authentication fails; if false, prompt and wait for the user to re-enter correct credentials before returning

Returns
`String`	An auth token of the specified type for this account, or null if authentication fails or none can be fetched.

Throws
`AuthenticatorException`	if the authenticator failed to respond
`OperationCanceledException`	if the request was canceled for any reason, including the user canceling a credential request
`IOException`	if the authenticator experienced an I/O problem creating a new auth token, usually because of network trouble

clearPassword

Added in API level 5

public void clearPassword (Account account)

Forgets a saved password. This erases the local copy of the password; it does not change the user's account password on the server. Has the same effect as setPassword(account, null) but requires fewer permissions, and may be used by applications or management interfaces to "sign out" from an account.

This method only successfully clear the account's password when the caller has the same signature as the authenticator that owns the specified account. Otherwise, this method will silently fail.

It is safe to call this method from the main thread.

Parameters
`account`	`Account`: The account whose password to clear

confirmCredentials

Added in API level 5

public AccountManagerFuture<Bundle> confirmCredentials (Account account, 
                Bundle options, 
                Activity activity, 
                AccountManagerCallback<Bundle> callback, 
                Handler handler)

Confirms that the user knows the password for an account to make extra sure they are the owner of the account. The user-entered password can be supplied directly, otherwise the authenticator for this account type prompts the user with the appropriate interface. This method is intended for applications which want extra assurance; for example, the phone lock screen uses this to let the user unlock the phone with an account password if they forget the lock pattern.

If the user-entered password matches a saved password for this account, the request is considered valid; otherwise the authenticator verifies the password (usually by contacting the server).

This method may be called from any thread, but the returned AccountManagerFuture must not be used on the main thread.

Parameters
`account`	`Account`: The account to confirm password knowledge for
`options`	`Bundle`: Authenticator-specific options for the request; if the `KEY_PASSWORD` string field is present, the authenticator may use it directly rather than prompting the user; may be null or empty
`activity`	`Activity`: The `Activity` context to use for launching a new authenticator-defined sub-Activity to prompt the user to enter a password; used only to call startActivity(); if null, the prompt will not be launched directly, but the necessary `Intent` will be returned to the caller instead
`callback`	`AccountManagerCallback`: Callback to invoke when the request completes, null for no callback
`handler`	`Handler`: `Handler` identifying the callback thread, null for the main thread

Returns

Returns
`AccountManagerFuture<Bundle>`	An `AccountManagerFuture` which resolves to a Bundle with these fields if activity or password was supplied and the account was successfully verified: `KEY_ACCOUNT_NAME` - the name of the account verified `KEY_ACCOUNT_TYPE` - the type of the account `KEY_BOOLEAN_RESULT` - true to indicate success If no activity or password was specified, the returned Bundle contains `KEY_INTENT` with the `Intent` needed to launch the password prompt. Also the returning Bundle may contain `KEY_LAST_AUTHENTICATED_TIME` indicating the last time the credential was validated/created. If an error occurred,`AccountManagerFuture.getResult()` throws: `AuthenticatorException` if the authenticator failed to respond `OperationCanceledException` if the operation was canceled for any reason, including the user canceling the password prompt `IOException` if the authenticator experienced an I/O problem verifying the password, usually because of network trouble

AccountManagerFuture<Bundle>

KEY_ACCOUNT_NAME - the name of the account verified
KEY_ACCOUNT_TYPE - the type of the account
KEY_BOOLEAN_RESULT - true to indicate success

If no activity or password was specified, the returned Bundle contains KEY_INTENT with the Intent needed to launch the password prompt.

Also the returning Bundle may contain KEY_LAST_AUTHENTICATED_TIME indicating the last time the credential was validated/created. If an error occurred,AccountManagerFuture.getResult() throws:

AuthenticatorException if the authenticator failed to respond
OperationCanceledException if the operation was canceled for any reason, including the user canceling the password prompt
IOException if the authenticator experienced an I/O problem verifying the password, usually because of network trouble

editProperties

Added in API level 5

public AccountManagerFuture<Bundle> editProperties (String accountType,

                AccountManagerCallback<Bundle> callback, 
                Handler handler)

Offers the user an opportunity to change an authenticator's settings. These properties are for the authenticator in general, not a particular account. Not all authenticators support this method.

This method may be called from any thread, but the returned AccountManagerFuture must not be used on the main thread.

This method requires the caller to have the same signature as the authenticator associated with the specified account type.

Parameters
`accountType`	`String`: The account type associated with the authenticator to adjust
`activity`	`Activity`: The `Activity` context to use for launching a new authenticator-defined sub-Activity to adjust authenticator settings; used only to call startActivity(); if null, the settings dialog will not be launched directly, but the necessary `Intent` will be returned to the caller instead

get

Added in API level 5

public static AccountManager get (Context context)

Gets an AccountManager instance associated with a Context. The Context will be used as long as the AccountManager is active, so make sure to use a Context whose lifetime is commensurate with any listeners registered to addOnAccountsUpdatedListener(OnAccountsUpdateListener, Handler, boolean) or similar methods.

It is safe to call this method from the main thread.

No permission is required to call this method.

Parameters
`context`	`Context`: The `Context` to use when necessary

Returns
`AccountManager`	An `AccountManager` instance

getAccountVisibility

Added in API level 26

                String packageName)

Get visibility of certain account for given application. Possible returned values are:

This method requires the caller to have a signature match with the authenticator that owns the specified account.

Parameters
`account`	`Account`: `Account` to get visibility
`packageName`	`String`: Package name of the application to get account visibility

Returns
`int`	int Visibility of given account. For the caller targeting API level 34 and above, `VISIBILITY_NOT_VISIBLE` is returned if the given package is filtered by the rules of package visibility.

getAccounts

Added in API level 5

public Account[] getAccounts ()

Lists all accounts visible to the caller regardless of type. Equivalent to getAccountsByType(null). These accounts may be visible because the user granted access to the account, or the AbstractAccountAuthenticator managing the account did so or because the client shares a signature with the managing AbstractAccountAuthenticator.

Caution: This method returns personal and sensitive user data. If your app accesses, collects, uses, or shares personal and sensitive data, you must clearly disclose that fact to users. For apps published on Google Play, policies protecting user data require that you do the following:

Disclose to the user how your app accesses, collects, uses, or shares personal and sensitive data. Learn more about acceptable disclosure and consent.
Provide a privacy policy that describes your use of this data on- and off-device.

To learn more, visit the Google Play Policy regarding user data.

It is safe to call this method from the main thread.
Requires Manifest.permission.GET_ACCOUNTS

Returns
`Account[]`	An array of `Account`, one for each account. Empty (never null) if no accounts have been added.

getAccountsAndVisibilityForPackage

Added in API level 26

public Map<Account, Integer> getAccountsAndVisibilityForPackage (String packageName, 
                String accountType)

Gets all accounts of given type and their visibility for specific package. This method requires the caller to have a signature match with the authenticator that manages accountType. It is a helper method which combines calls to getAccountsByType(String) by authenticator and getAccountVisibility(Account, String) for every returned account.

Parameters
`packageName`	`String`: Package name
`accountType`	`String`: `Account` type

Returns
`Map<Account, Integer>`	Map with visibility for all accounts of given type See `getAccountVisibility(Account, String)` for possible values

getAccountsByType

Added in API level 5

public Account[] getAccountsByType (String type)

Lists all accounts of particular type visible to the caller. These accounts may be visible because the user granted access to the account, or the AbstractAccountAuthenticator managing the account did so or because the client shares a signature with the managing AbstractAccountAuthenticator.

The account type is a string token corresponding to the authenticator and useful domain of the account. For example, there are types corresponding to Google and Facebook. The exact string token to use will be published somewhere associated with the authenticator in question.

Disclose to the user how your app accesses, collects, uses, or shares personal and sensitive data. Learn more about acceptable disclosure and consent.
Provide a privacy policy that describes your use of this data on- and off-device.

To learn more, visit the Google Play Policy regarding user data.

It is safe to call this method from the main thread.

Caller targeting API level Build.VERSION_CODES.O and above, will get list of accounts made visible to it by user (see newChooseAccountIntent(android.accounts.Account, java.util.List, java.lang.String[], java.lang.String, java.lang.String, java.lang.String[], android.os.Bundle)) or AbstractAccountAuthenticator using setAccountVisibility(Account, String, int). Manifest.permission.GET_ACCOUNTS permission is not used.

Caller targeting API level below Build.VERSION_CODES.O that have not been granted the Manifest.permission.GET_ACCOUNTS permission, will only see those accounts managed by AbstractAccountAuthenticators whose signature matches the client.

NOTE: If targeting your app to work on API level Build.VERSION_CODES.LOLLIPOP_MR1 and before, Manifest.permission.GET_ACCOUNTS permission is needed for those platforms, irrespective of uid or signature match. See docs for this function in API level Build.VERSION_CODES.LOLLIPOP_MR1.
Requires Manifest.permission.GET_ACCOUNTS

Parameters
`type`	`String`: The type of accounts to return, null to retrieve all accounts

Returns
`Account[]`	An array of `Account`, one per matching account. Empty (never null) if no accounts of the specified type have been added.

getAccountsByTypeAndFeatures

Added in API level 5

public AccountManagerFuture<Account[]> getAccountsByTypeAndFeatures (String type, 
                String[] features, 
                AccountManagerCallback<Account[]> callback, 
                Handler handler)

Lists all accounts of a type which have certain features. The account type identifies the authenticator (see getAccountsByType(String)). Account features are authenticator-specific string tokens identifying boolean account properties (see hasFeatures(Account, String, AccountManagerCallback, Handler)).

Unlike getAccountsByType(String), this method calls the authenticator, which may contact the server or do other work to check account features, so the method returns an AccountManagerFuture.

This method may be called from any thread, but the returned AccountManagerFuture must not be used on the main thread.

Parameters
`type`	`String`: The type of accounts to return, must not be null
`features`	`String`: An array of the account features to require, may be null or empty *
`callback`	`AccountManagerCallback`: Callback to invoke when the request completes, null for no callback
`handler`	`Handler`: `Handler` identifying the callback thread, null for the main thread

Returns
`AccountManagerFuture<Account[]>`	An `AccountManagerFuture` which resolves to an array of `Account`, one per account of the specified type which matches the requested features.

getAccountsByTypeForPackage

Added in API level 18

public Account[] getAccountsByTypeForPackage (String type, 
                String packageName)

Returns the accounts visible to the specified package in an environment where some apps are not authorized to view all accounts. This method can only be called by system apps and authenticators managing the type. Beginning API level Build.VERSION_CODES.O it also return accounts which user can make visible to the application (see VISIBILITY_USER_MANAGED_VISIBLE).

Parameters
`type`	`String`: The type of accounts to return, null to retrieve all accounts
`packageName`	`String`: The package name of the app for which the accounts are to be returned

Returns
`Account[]`	An array of `Account`, one per matching account. Empty (never null) if no accounts of the specified type can be accessed by the package.

getAuthToken

Added in API level 14

public AccountManagerFuture<Bundle> getAuthToken (Account account, 
                String authTokenType, 
                Bundle options, 
                boolean notifyAuthFailure, 
                AccountManagerCallback<Bundle> callback, 
                Handler handler)

Gets an auth token of the specified type for a particular account, optionally raising a notification if the user must enter credentials. This method is intended for background tasks and services where the user should not be immediately interrupted with a password prompt.

If a previously generated auth token is cached for this account and type, then it is returned. Otherwise, if a saved password is available, it is sent to the server to generate a new auth token. Otherwise, an Intent is returned which, when started, will prompt the user for a password. If the notifyAuthFailure parameter is set, a status bar notification is also created with the same Intent, alerting the user that they need to enter a password at some point.

In that case, you may need to wait until the user responds, which could take hours or days or forever. When the user does respond and supply a new password, the account manager will broadcast the LOGIN_ACCOUNTS_CHANGED_ACTION Intent and notify OnAccountsUpdateListener which applications can use to try again.

If notifyAuthFailure is not set, it is the application's responsibility to launch the returned Intent at some point. Either way, the result from this call will not wait for user action.

Some authenticators have auth token types, whose value is authenticator-dependent. Some services use different token types to access different functionality -- for example, Google uses different auth tokens to access Gmail and Google Calendar for the same account.

This method may be called from any thread, but the returned AccountManagerFuture must not be used on the main thread.

Parameters
`account`	`Account`: The account to fetch an auth token for
`authTokenType`	`String`: The auth token type, an authenticator-dependent string token, must not be null
`options`	`Bundle`: Authenticator-specific options for the request, may be null or empty
`notifyAuthFailure`	`boolean`: True to add a notification to prompt the user for a password if necessary, false to leave that to the caller
`callback`	`AccountManagerCallback`: Callback to invoke when the request completes, null for no callback
`handler`	`Handler`: `Handler` identifying the callback thread, null for the main thread

Returns

Returns
`AccountManagerFuture<Bundle>`	An `AccountManagerFuture` which resolves to a Bundle with at least the following fields on success: `KEY_ACCOUNT_NAME` - the name of the account you supplied `KEY_ACCOUNT_TYPE` - the type of the account `KEY_AUTHTOKEN` - the auth token you wanted (Other authenticator-specific values may be returned.) If the user must enter credentials, the returned Bundle contains only `KEY_INTENT` with the `Intent` needed to launch a prompt. If an error occurred, `AccountManagerFuture.getResult()` throws: `AuthenticatorException` if the authenticator failed to respond `OperationCanceledException` if the operation is canceled for any reason, incluidng the user canceling a credential request `IOException` if the authenticator experienced an I/O problem creating a new auth token, usually because of network trouble If the account is no longer present on the device, the return value is authenticator-dependent. The caller should verify the validity of the account before requesting an auth token.

This method may be called from any thread, but the returned AccountManagerFuture must not be used on the main thread.
Requires android.Manifest.permission.USE_CREDENTIALS

Parameters
`account`	`Account`: The account to fetch an auth token for
`authTokenType`	`String`: The auth token type, an authenticator-dependent string token, must not be null
`notifyAuthFailure`	`boolean`: True to add a notification to prompt the user for a password if necessary, false to leave that to the caller
`callback`	`AccountManagerCallback`: Callback to invoke when the request completes, null for no callback
`handler`	`Handler`: `Handler` identifying the callback thread, null for the main thread

Returns

Returns
`AccountManagerFuture<Bundle>`	An `AccountManagerFuture` which resolves to a Bundle with at least the following fields on success: `KEY_ACCOUNT_NAME` - the name of the account you supplied `KEY_ACCOUNT_TYPE` - the type of the account `KEY_AUTHTOKEN` - the auth token you wanted (Other authenticator-specific values may be returned.) If the user must enter credentials, the returned Bundle contains only `KEY_INTENT` with the `Intent` needed to launch a prompt. If an error occurred, `AccountManagerFuture.getResult()` throws: `AuthenticatorException` if the authenticator failed to respond `OperationCanceledException` if the operation is canceled for any reason, incluidng the user canceling a credential request `IOException` if the authenticator experienced an I/O problem creating a new auth token, usually because of network trouble If the account is no longer present on the device, the return value is authenticator-dependent. The caller should verify the validity of the account before requesting an auth token.

AccountManagerFuture<Bundle>

public AccountManagerFuture<Bundle> startUpdateCredentialsSession (Account account, 
                String authTokenType, 
                Bundle options, 
                Activity activity, 
                AccountManagerCallback<Bundle> callback, 
                Handler handler)

Asks the user to enter a new password for the account but not updating the saved credentials for the account until finishSession(Bundle, Activity, AccountManagerCallback, Handler) is called.

This method may be called from any thread, but the returned AccountManagerFuture must not be used on the main thread.

NOTE: The saved credentials for the account alone will not be updated by calling this API alone. #finishSession should be called after this to update local credentials

Parameters
`account`	`Account`: The account to update credentials for
`authTokenType`	`String`: The credentials entered must allow an auth token of this type to be created (but no actual auth token is returned); may be null
`options`	`Bundle`: Authenticator-specific options for the request; may be null or empty
`activity`	`Activity`: The `Activity` context to use for launching a new authenticator-defined sub-Activity to prompt the user to enter a password; used only to call startActivity(); if null, the prompt will not be launched directly, but the necessary `Intent` will be returned to the caller instead
`callback`	`AccountManagerCallback`: Callback to invoke when the request completes, null for no callback
`handler`	`Handler`: `Handler` identifying the callback thread, null for the main thread

Returns

AccountManagerFuture<Bundle>

An AccountManagerFuture which resolves to a Bundle with these fields if an activity was supplied and user was successfully re-authenticated to the account:

KEY_ACCOUNT_SESSION_BUNDLE - encrypted Bundle for updating the local credentials on device later.
KEY_ACCOUNT_STATUS_TOKEN - optional, token to check status of the account

If no activity was specified, the returned Bundle contains KEY_INTENT with the Intent needed to launch the password prompt. If an error occurred, AccountManagerFuture.getResult() throws:

AuthenticatorException if the authenticator failed to respond
OperationCanceledException if the operation was canceled for any reason, including the user canceling the password prompt
IOException if the authenticator experienced an I/O problem verifying the password, usually because of network trouble

updateCredentials

Added in API level 5

public AccountManagerFuture<Bundle> updateCredentials (Account account, 
                String authTokenType, 
                Bundle options, 
                Activity activity, 
                AccountManagerCallback<Bundle> callback, 
                Handler handler)

Asks the user to enter a new password for an account, updating the saved credentials for the account. Normally this happens automatically when the server rejects credentials during an auth token fetch, but this can be invoked directly to ensure we have the correct credentials stored.

This method may be called from any thread, but the returned AccountManagerFuture must not be used on the main thread.

Parameters
`account`	`Account`: The account to update credentials for
`authTokenType`	`String`: The credentials entered must allow an auth token of this type to be created (but no actual auth token is returned); may be null
`options`	`Bundle`: Authenticator-specific options for the request; may be null or empty
`activity`	`Activity`: The `Activity` context to use for launching a new authenticator-defined sub-Activity to prompt the user to enter a password; used only to call startActivity(); if null, the prompt will not be launched directly, but the necessary `Intent` will be returned to the caller instead
`callback`	`AccountManagerCallback`: Callback to invoke when the request completes, null for no callback
`handler`	`Handler`: `Handler` identifying the callback thread, null for the main thread

Returns

AccountManagerFuture<Bundle>

An AccountManagerFuture which resolves to a Bundle with these fields if an activity was supplied and the account credentials were successfully updated:

KEY_ACCOUNT_NAME - the name of the account
KEY_ACCOUNT_TYPE - the type of the account

If no activity was specified, the returned Bundle contains KEY_INTENT with the Intent needed to launch the password prompt. If an error occurred, AccountManagerFuture.getResult() throws:

AuthenticatorException if the authenticator failed to respond
OperationCanceledException if the operation was canceled for any reason, including the user canceling the password prompt
IOException if the authenticator experienced an I/O problem verifying the password, usually because of network trouble
