java - 错误 : Class not found when unmarshalling: com. facebook.login.Login 客户端请求

Question

点击“使用 Facebook 登录”(简单登录按钮)时出现此错误。

我有谷歌，并在这里阅读其他主题 - 但我看不到任何与我的问题相符的内容。

我在下面添加 Login.java 类。

public class Login extends Activity {



/**
 * Called when the activity is first created.
 */

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_login);
    CallbackManager callbackManager = CallbackManager.Factory.create();
    LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
    loginButton.setReadPermissions("public_profile", "email", "user_friends");

    // Other app specific specialization

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {


        @Override
        public void onSuccess(LoginResult loginResult) {

            Log.i("Login", "Logged in: ");
          Intent i = new Intent(Login.this, MainActivity.class);
            startActivity(i);
        }

        @Override
        public void onCancel() {
            // App code

        }

        @Override
        public void onError(FacebookException exception) {
            // App code
            Log.i("Error" , "Error");
        }


    });
}
}

检查 Activity 上的 android:noHistory 标志。
