Пожалуйста, помогите мне исправить java .lang.ClassNotFoundException: не удалось найти класс «android .view.View $ OnUnhandledKeyEventListener»

Question

Я нашел ответ на вышеуказанный запрос здесь

AndroidX: Appcompat I: art error android .view.View $ OnUnhandledKeyEventListener

Но я не получаю что куда девать эти коды. Мне не удалось найти ViewCompat.class , а также структуру пакета поддержки . Построить градиент для приложения, как показано ниже

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "29.0.3"

    defaultConfig {
        applicationId "com.example.tailor2app"
        minSdkVersion 23
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'com.google.android.material:material:1.1.0'
    implementation 'com.android.support:support-core-utils:28.0.0'
    implementation 'androidx.legacy:legacy-support-v13:1.0.0'

    configurations.all {
        resolutionStrategy.eachDependency { DependencyResolveDetails details ->
            def requested = details.requested
            if (requested.group == "androidx") {
                if (!requested.name.startsWith("${targetSdk}.+")) {
                    details.useVersion "26.+"
                }
            }
        }
    }

}

ОШИБКИ такие
