java - Kotlin - list 合并失败 : Attribute application@appComponentFactory

Question

我还是 Android 应用程序的初学者，因此当我尝试构建此应用程序时，我在日志中收到以下错误:

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).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-31:19 to override.

并且 build.grade 文件具有此依赖项

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'
    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-auth:16.1.0'
    implementation 'com.google.firebase:firebase-core:16.0.1'
    implementation 'com.google.firebase:firebase-storage:16.0.5'
    implementation 'com.google.firebase:firebase-database:16.0.5'
    implementation 'de.hdodenhof:circleimageview:3.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.xwray:groupie:2.3.0'
    implementation 'com.xwray:groupie-kotlin-android-extensions:2.3.0'
    implementation 'com.squareup.picasso:picasso:2.71828'
}

我尝试用谷歌搜索解决方案，但一无所获。

Answer 1

将这些行添加到 gradle.properties 文件中:

android.useAndroidX=true
android.enableJetifier=true

说明:部分依赖项，例如 com.xwray:groupie:2.3.0，使用 Android X。Jetifier需要在 Android X 中使用 android.support.* 类，如建议 here .
