Question

我是android studio的初学者。尝试使用Retrofit进行基本API调用，用于PHP API调用，用于登录。对不起，如果我问这样的问题可能是错误的，请纠正我。

代码：

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        prefConfig = new PrefConfig(this);
        apiInterface = ApiClient.getApiClient().create(ApiInterface.class); //Here


        if (findViewById(R.id.fragment_container) != null) {
            if (savedInstanceState != null) {
                return;
            }

            if (prefConfig.readLoginStatus()) {
                getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, new WelcomeFragment()).commit();
            } else {
                getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, new LoginFragment()).commit();
            }
        }
    }

当我评论标记为Here的行时，一切都很顺利。
