java Android studio用户注册数据未插入firebase数据库

Question

我上面的代码是将用户注册数据插入firebase数据库。但是，当我构建应用程序并尝试将一些演示数据插入数据库以执行用户注册时，没有一个数据被插入firebase。有人能检查我的代码，找出我做错了什么吗

public class CreateProfile extends AppCompatActivity {

    EditText etName,etBio,etProfession,etEmail,etWeb;

    All_User_Member member;
    String currentUserId;


    @Override

        super.onCreate(savedInstanceState);
