Java 如何修复错误：找不到symbol import com.stripe.android.TokenCallback；

我在这行代码中遇到了问题，这里是TokenCallback（） 我不知道如何用另一种方法来代替这个方法，使它起作用 每次编译代码时，我都会得到相同的错误标记Callback总是 以红色突出显示。它也不允许我使用这个库。不管什么原因，这个库似乎不再工作了

package com.example.androidstripepayments;
import androidx.appcompat.app.AppCompatActivity;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;



import com.parse.FunctionCallback;
import com.parse.ParseCloud;
import com.stripe.android.Stripe;

import com.stripe.android.TokenCallback;
import com.stripe.android.model.Card;
import com.stripe.android.model.Token;
import java.text.ParseException;
import java.util.HashMap;

//import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    public static final String PUBLISHABLE_KEY = "pk_test_qeSW2ZpZCFBZe0";
    private Card card;
    private ProgressDialog progress;
    private Button purchase;

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



        card = new Card(
                "4242424242424242", //card number
                12, //expMonth
                2030,//expYear
                "123"//cvc
        );
        progress = new ProgressDialog(this);
        purchase = (Button) findViewById(R.id.purchase);
        purchase.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                buy();
            }
        });
    }

    private void buy(){
        boolean validation = card.validateCard();
        if(validation){
            startProgress("Validating Credit Card");
            new Stripe(this).createToken(
                    card,
                    PUBLISHABLE_KEY,

这是我的版本。gradle（模块） 我确保在这里添加了所有正确的内容

   // Top-level build file where you can add configuration options common to all sub-    projects/modules.

    buildscript {

        repositories {
            google()
            jcenter()

        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.6.0'


            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }

    allprojects {
        repositories {
            google()
            jcenter()

        }
    }

    allprojects {
        repositories {

            maven { url "https://jitpack.io" }
        }
    }

    task clean(type: Delete) {
        delete rootProject.buildDir
    }

Jonas，自Stripe Android版本v11.0.0以来，TokenCallback已被删除。您可能正在使用较新版本的库

实现'com.Stripe:Stripe Android:+'
