我不知道 appcompat:design:1.1.0 我的错误在哪里

Question

应用程序兼容性：设计：1.1.0

不知道哪里错了。可能在 appcompat:design:1.1.0 但我不知道我做错了什么。顺便说一句，我是新来的 :)

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 15
        targetSdkVersion 29
        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.appcompat:design:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.firebase:firebase-auth:19.2.0'
    implementation 'com.google.firebase:firebase-database:19.2.0'
    implementation 'com.google.firebase:firebase-storage:19.1.0'
    testImplementation 'junit:junit:4.13'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

图书馆androidx.appcompat:design不存在。

删除这个依赖：

implementation 'androidx.appcompat:design:1.1.0'

并添加 Material Components Library.

Material Components for Android is a drop-in replacement for Android's Design Support Library.

添加这些依赖项之一：

implementation 'com.google.android.material:material:1.0.0' //stable release
implementation 'com.google.android.material:material:1.1.0' //stable release
implementation 'com.google.android.material:material:1.2.0-alpha03' //alpha release

我不知道 appcompat:design:1.1.0 我的错误在哪里

I don't know where is my mistake at the appcompat:design:1.1.0

java

android

android-support-library

material-components-android
