JavaSnap login issues

Question

I can't seem to log in to Snapchat using the JavaSnap API, https://github.com/hatboysam/JavaSnap, even when I provide the correct login information.

The code I used:

Snapchat sc = Snapchat.login(usernameLogin.getText(), passwordLogin.getText());

if (sc != null) {
   System.out.println("Login Successful");
} else {
   System.out.println("Login Failed");
}

By looking at the example Main class. logging in is successful when sc is not null, however, it is always null here.

The logging in part in the example Main class.

snapchat = Snapchat.login(username, password);
if (snapchat != null) {
    System.out.println("Logged in.");
} else {
    System.out.println("Failed to log in.");
    return;
}
