I am having trouble with this line right here with TokenCallback()
And I dont know how to replace this method with another method to make it work
Every time i compile the code I always get the same error TokenCallback is always
highlighted in red. It also not allowing me to use the library This library does not seem to work anymore for what ever reason.

                    new TokenCallback() {
                        @Override
                        public void onError(Exception error) {
                            Toast.makeText(MainActivity.this,
                                    "Stripe -" + error.toString(),
                                    Toast.LENGTH_LONG).show();
                        }

                        @Override
                        public void onSuccess(Token token) {
                            finishProgress();
                            charge(token);
                        }
                    });
        } else if (!card.validateNumber()) {

this is the build.gradle(Project:)
Im pretty sure I added all the right dependencies

   // 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
    }
