/**
|
|
* 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.
|
|
*
|
|
* <p>Different online services have different ways of handling accounts and
|
|
* authentication, so the account manager uses pluggable <em>authenticator</em>
|
|
* modules for different <em>account types</em>. 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.
|
|
*
|
|
* <p>Many servers support some notion of an <em>authentication token</em>,
|
|
* 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 <em>invalidate</em> auth tokens when they stop working so
|
|
* the AccountManager knows it needs to regenerate them.
|
|
*
|
|
* <p>Applications accessing a server normally go through these steps:
|
|
*
|
|
* <ul>
|
|
* <li>Get an instance of AccountManager using {@link #get(Context)}.
|
|
*
|
|
* <li>List the available accounts using {@link #getAccountsByType} or
|
|
* {@link #getAccountsByTypeAndFeatures}. Normally applications will only
|
|
* be interested in accounts with one particular <em>type</em>, which
|
|
* identifies the authenticator. Account <em>features</em> 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.
|
|
*
|
|
* <li>Select one or more of the available accounts, possibly by asking the
|
|
* user for their preference. If no suitable accounts are available,
|
|
* {@link #addAccount} may be called to prompt the user to create an
|
|
* account of the appropriate type.
|
|
*
|
|
* <li><b>Important:</b> 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 {@link #getAccountsByType}. Requesting an auth token
|
|
* for an account no longer on the device results in an undefined failure.
|
|
*
|
|
* <li>Request an auth token for the selected account(s) using one of the
|
|
* {@link #getAuthToken} methods or related helpers. Refer to the description
|
|
* of each method for exact usage and error handling details.
|
|
*
|
|
* <li>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.
|
|
*
|
|
* <li><b>Important:</b> 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 {@link #invalidateAuthToken} 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.
|
|
* </ul>
|
|
*
|
|
* <p>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 {@link Activity} context.
|
|
*
|
|
* <p>Many AccountManager methods take {@link AccountManagerCallback} and
|
|
* {@link Handler} as parameters. These methods return immediately and
|
|
* run asynchronously. If a callback is provided then
|
|
* {@link AccountManagerCallback#run} will be invoked on the Handler's
|
|
* thread when the request completes, successfully or not.
|
|
* The result is retrieved by calling {@link AccountManagerFuture#getResult()}
|
|
* on the {@link 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
|
|
* {@link AccountManagerFuture#getResult()} immediately on receiving the
|
|
* future from the method; no callback need be supplied.
|
|
*
|
|
* <p>Requests which may block, including
|
|
* {@link AccountManagerFuture#getResult()}, must never be called on
|
|
* the application's main event thread. These operations throw
|
|
* {@link IllegalStateException} if they are used on the main thread.
