Using an already existing account is pretty easy, which means in the
case of Droid Facebook, Google and Exchange. Writing the actual
account providers is the hard part.
I'm just coding this off the top of my head, since I haven't finished
writing an authenticator yet (and the SDK has no built-in accounts)
but something along the lines of this:
/**
NOTE: This code blocks and is the wrong way to write this if
you are
doing it in the main thread. In the main thread you should pass in a
callback and wait for notification of success. For simplicity of
posting the code to this group though I have written it this way.
**/
AccountManager myAccountManager = AccountManager.get(this);
Account foundGoogleAccount;
// TODO: Do what you did to find a Google account.
AccountManagerFuture<Bundle> myAccountManagerFuture;
// TODO: I *think* that the Activity that getAuthToken is
asking for
is the activity to launch the intent from, not the actual activity
that the intent will launch. This means that the intent which leads
to a credential prompt from the user will appear on top of the passed
in Activity in the Activity stack. However, this is not clear in the
documentation so needs testing.
// TODO: Figure out if "com.google" account type needs any
additional login options passed in. In this call I don't pass in any
login options but every authenticator has the option of requiring
some. I assume this would be something like an RSA one-time-password
that can't be stored, though the authenticator could also get that via
a credential prompt instead of as a login option. It may also be used
if a user can authenticate an account with some set of optional
parameters, such as authenticate for viewing only.
myAccountManagerFuture = myAccountManager.getAuthToken
(foundGoogleAccount, "com.google", null, this, null, null);
// THE FOLLOWING CALL BLOCKS WHILE AUTHENTICATION IS DONE!
Normally
you would wait for a callback with the result, but for simplicity we
do this instead.
Bundle myAuthTokenBundle;
try
{
myAuthTokenBundle = myAccountManagerFuture.getResult();
}
catch (OperationCanceledException e)
{
e.printStackTrace();
return;
}
catch (AuthenticatorException e)
{
e.printStackTrace();
return;
}
catch (IOException e)
{
e.printStackTrace();
return;
}
if
(myAuthTokenBundle.getString(AccountManager.KEY_ACCOUNT_TYPE) !=
"com.google")
{
// TODO: Handle auth failure case.
return;
}
String myAccountName = myAuthTokenBundle.getString
(AccountManager.KEY_ACCOUNT_NAME);
String myAccountType = myAuthTokenBundle.getString
(AccountManager.KEY_ACCOUNT_TYPE);
// TODO: Figure out the type of auth token. Is it always a
String
or something? Does it depend on the Authenticator?
Object myGoogleAuthToken = myAuthTokenBundle.get
(AccountManager.KEY_AUTHTOKEN);
