android - 由于 Androidx 和 Android 支持最新版本之间的冲突导致构建错误

Question

由于标题中定义的一些冲突，我遇到了构建错误。这是我的错误：

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).

这是我的 build.grade 文件：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 28
defaultConfig {
    applicationId "com.****.****"
    minSdkVersion 17
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:design:28.0.0'
implementation 'com.google.firebase:firebase-database:18.0.0'
implementation 'com.google.android.gms:play-services-maps:17.0.0'
implementation 'com.google.firebase:firebase-messaging:19.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

implementation 'com.google.firebase:firebase-core:17.0.0'
implementation 'com.google.firebase:firebase-auth:18.0.0'
implementation 'com.google.android.gms:play-services-location:17.0.0'

implementation 'com.google.firebase:firebase-storage:18.0.0'

implementation 'com.sdsmdg.harjot:vectormaster:1.1.3'

  }
 apply plugin: 'com.google.gms.google-services'

模块级别的 build.gradle 是：

buildscript {
ext.kotlin_version = '1.3.40'
repositories {
    google()
    jcenter()

}
dependencies {
    classpath 'com.android.tools.build:gradle:3.4.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.2.0'

}
}

allprojects {
repositories {
    google()
    jcenter()
    maven{
        url "https://maven.google.com"
    }
    maven { url 'https://jitpack.io' }

}
}

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

有人可以给我指点这里的问题吗？在我更新了 android studio 并在其中添加了 firebase 存储之后，该错误才开始出现

只需添加：

implementation 'com.android.support:appcompat-v7:28.0.0'

给我一个错误如下：

Dependencies using groupId com.android.support and androidx.* can not be combined but found IdeMavenCoordinates{myGroupId='com.android.support', myArtifactId='support-fragment', myVersion='28.0.0', myPacking='aar', myClassifier='null'} and IdeMavenCoordinates{myGroupId='androidx.versionedparcelable', myArtifactId='versionedparcelable', myVersion='1.0.0', myPacking='aar', myClassifier='null'} incompatible dependencies
