更新到 sdk 28 时出现 android gradle 错误

Question

当我将 sdk 版本从 27 更新到 28 时，我在模块应用程序的独立性中出现错误，来自这部分的构建 gradle。

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

它抛出这个错误:

Dependencies using groupId com.android.support and androidx.* can not be combined

我不想迁移到 androidx，所以我需要解决这个问题才能使构建 gradle 正常工作。

这是模块应用:

apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
    applicationId "com.xxxxxxxx.xxxxx"
    minSdkVersion 19
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
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'

这是build.gradle

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'


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

    classpath 'com.google.gms:google-services:3.2.0'
}
}
allprojects {
repositories {
    google()
    jcenter()
    maven { url "https://jitpack.io" }
    maven { url "https://maven.google.com" }}

Answer 1

我添加了几行android studio建议的代码并且它有效

    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support:animated-vector-drawable:28.0.0'
    implementation 'com.android.support:support-media-compat:28.0.0'
