Answer
When a task fails, it contains an exception that explains the reason of the failure. Log this reason to know more about the cause of the problem:
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
addClassToFirebase();
Intent intent = new Intent(signup.this, MainActivity.class);
intent.putExtra("etsufn", ETname.getText().toString());
startActivity(intent);
} else {
// If sign in fails, display a message to the user.
Toast.makeText(signup.this, "Authintication failed", Toast.LENGTH_SHORT).show();
Log.e("AUTH", "Authentication failed", task.getException()); // 👈
}
Also see the reference documentation for the Task class.
