尝试集成 Stripe 时应用强制关闭

Question

我正在尝试集成 Stripe 以在我的 Android 应用程序中处理付款。

我让用户输入信用卡信息，然后我现在要做的就是创建一个令牌。但是当我单击按钮时，应用程序强制关闭。

这不是最终应用程序接受卡片和使用 Stripe 的方式，但我只是想了解我将来如何集成 Stripe

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.Spinner;
import android.widget.Toast;

import com.stripe.android.*;
import com.stripe.android.model.Card;
import com.stripe.android.model.Token;
import com.stripe.android.Stripe;

import java.util.HashMap;
import java.util.Map;

public class newUser extends AppCompatActivity {

String fname;
String lname;
String email;
String phonenum;
String pin;
String cardNumber;
String cardCVC;
Integer cardExpMonth;
Integer cardExpYear;
String stripetok;
Card cardNew;

private static final String PUBLISHABLE_KEY = "pk_test_iUVdhdvJuurqSxIlXpzq32LS";
UserDBHelper newUserr;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_new_user);

    newUserr = new UserDBHelper(newUser.this);

    EditText fNameh = (EditText) findViewById(R.id.fNameNew);
    EditText lNameh = (EditText) findViewById(R.id.lNameNew);
    EditText emailh = (EditText) findViewById(R.id.emailNew);
    EditText phoneNumh = (EditText) findViewById(R.id.phoneNew);
    EditText pinh = (EditText) findViewById(R.id.pinNew);
    EditText cardNumberh = (EditText) findViewById(R.id.cardNumNew);
    EditText cardCVCh = (EditText) findViewById(R.id.cvcNew);
    Spinner cardExpMonthh = (Spinner) findViewById(R.id.monthNew);
    Spinner cardExpYearh = (Spinner) findViewById(R.id.yearNew);

    fname = fNameh.getText().toString();
    lname = lNameh.getText().toString();
    email = emailh.getText().toString();
    phonenum = phoneNumh.getText().toString();
    pin = pinh.getText().toString();
    cardNumber = cardNumberh.getText().toString();
    cardCVC = cardCVCh.getText().toString();
    cardExpMonth = (Integer) cardExpMonthh.getSelectedItem();
    cardExpYear = (Integer) cardExpYearh.getSelectedItem();


    cardNew = new Card(
            cardNumber,
            cardExpMonth,
            cardExpYear,
            cardCVC
    );

    ImageButton createNewUser = (ImageButton) findViewById(R.id.createNew);



    createNewUser.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v)
        {
            if(cardNew.validateCard() & cardNew.validateCVC()) {
                Stripe stripe = new Stripe();
                stripe.createToken(cardNew, PUBLISHABLE_KEY, new TokenCallback() {
                    public void onSuccess(Token token) {
                        // TODO: Send Token information to your backend to initiate a charge
                        Toast.makeText(
                                getApplicationContext(),
                                "Token created: " + token.getId(),
                                Toast.LENGTH_LONG).show();
                    }

                    public void onError(Exception error) {
                        Log.d("Stripe", error.getLocalizedMessage());
                    }
                });

            }

            else{
                Toast.makeText(
                        getApplicationContext(),
                        "Token not made!",
                        Toast.LENGTH_LONG).show();
            }

        }
    });

关于为什么会发生这种情况的任何想法？我没有收到任何错误，但活动甚至不会加载。

我已经加入了

compile 'com.stripe:stripe-android:2.0.2'

进入应用的build.gradle下的dependencies

感谢您的任何意见！

编辑 1： 我相信问题可能出在我将字符串从微调器中转换为整数时。

Answer 1

改变

cardExpMonth = (Integer) cardExpMonthh.getSelectedItem();
cardExpYear = (Integer) cardExpYearh.getSelectedItem();

到

cardExpMonth = Integer.valueOf(cardExpMonthh.getSelectedItem());
cardExpYear = Integer.valueOf(cardExpYearh.getSelectedItem());
