Parameters

response
AccountAuthenticatorResponse

to send the result back to the AccountManager, will never be null

account
Account

the account whose credentials are to be retrieved, will never be null

authTokenType
String

the type of auth token to retrieve, will never be null

options
Bundle

a Bundle of authenticator-specific options. It always contains AccountManager#KEY_CALLER_PID and AccountManager#KEY_CALLER_UID fields which will let authenticator know the identity of the caller.

Returns

a Bundle result or null if the result is to be returned via the response.

Attributes

Exceptions

if the authenticator could not honor the request due to a network error

Remarks

Gets an authtoken for an account.

If not null, the resultant Bundle will contain different sets of keys depending on whether a token was successfully issued and, if not, whether one could be issued via some android.app.Activity.

If a token cannot be provided without some additional activity, the Bundle should contain AccountManager#KEY_INTENT with an associated Intent. On the other hand, if there is no such activity, then a Bundle containing AccountManager#KEY_ERROR_CODE and AccountManager#KEY_ERROR_MESSAGE should be returned.

If a token can be successfully issued, the implementation should return the AccountManager#KEY_ACCOUNT_NAME and AccountManager#KEY_ACCOUNT_TYPE of the account associated with the token as well as the AccountManager#KEY_AUTHTOKEN. In addition AbstractAccountAuthenticator implementations that declare themselves android:customTokens=true may also provide a non-negative #KEY_CUSTOM_TOKEN_EXPIRY long value containing the expiration timestamp of the expiration time (in millis since the unix epoch), tokens will be cached in memory based on application's packageName/signature for however long that was specified.

Implementers should assume that tokens will be cached on the basis of account and authTokenType. The system may ignore the contents of the supplied options Bundle when determining to re-use a cached token. Furthermore, implementers should assume a supplied expiration time will be treated as non-binding advice.

Finally, note that for android:customTokens=false authenticators, tokens are cached indefinitely until some client calls AccountManager#invalidateAuthToken(String,String).
