/**

* A {@code LogInCallback} is used to run code after logging in a user.
|
|
* <p/>
|
|
* The easiest way to use a {@code LogInCallback} is through an anonymous inner class. Override the
|
|
* {@code done} function to specify what the callback should do after the login is complete.
|
|
* The {@code done} function will be run in the UI thread, while the login happens in a
|
|
* background thread. This ensures that the UI does not freeze while the save happens.
|
|
* <p/>
|
|
* For example, this sample code logs in a user and calls a different function depending on whether
|
|
* the login succeeded or not.
|
|
* <p/>

|
* loginSuccessful();
