private void fetchUserInfo() {
final AccessToken accessToken = AccessToken.getCurrentAccessToken();
if (accessToken != null) {
GraphRequest request = GraphRequest.newMeRequest(
accessToken, new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject me, GraphResponse response) {
user = me;
updateUI();
}
});
Bundle parameters = new Bundle();
parameters.putString(FIELDS, REQUEST_FIELDS);
request.setParameters(parameters);
GraphRequest.executeBatchAsync(request);
} else {
user = null;
}
}

The access token that was returned by the LoginManager will be saved in shared preferences,
so the next time the app is opened, AccessToken.getCurrentAccessToken()
should have the same access token, this is the same as how it with the Session class.
You can check out the samples provided with the SDK to see them work.
Make sure you're not reinstalling the app between sessions, or setting the current
access token to null explicitly.

you can use below method
Getter for the access token that is current for the application.
public static AccessToken getCurrentAccessToken()
Returns
The access token that is current for the application.
setCurrentAccessToken(AccessToken)
Setter for the access token that is current for the application.
public static void setCurrentAccessToken(AccessToken accessToken)
