Android-更新到API 28后出现构建错误（清单合并失败）

Question

我正在尝试使用最新的库作为我的要求的一部分。我确实将gradle版本升级到了3.1.4，并且所有支持库都具有匹配的compile和target SDK版本，但是在构建项目时，我得到

  

错误：清单合并失败：[com.android.support:support-compat:28.0.0] AndroidManifest.xml：22：18-中的属性application @ appComponentFactory value =（android.support.v4.app.CoreComponentFactory） 91       也存在于[androidx.core：core：1.0.0] AndroidManifest.xml：22：18-86 value =（androidx.core.app.CoreComponentFactory）。       建议：在AndroidManifest.xml：28：5-122：19的元素上添加'tools：replace =“ android：appComponentFactory”'以进行覆盖。

我的app-build.gradle看起来像这样：

buildscript {
repositories {
    maven { url 'https://maven.fabric.io/public' }
}

dependencies {
    classpath 'io.fabric.tools:gradle:1.+'

我的项目级别build.gradle看起来像这样

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

repositories {
    maven {
        url 'https://maven.fabric.io/public'
    }
    google()
    jcenter()

}
dependencies {
    classpath 'com.android.tools.build:gradle:3.4.1'
    classpath 'io.fabric.tools:gradle:1.29.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath 'com.google.gms:google-services:4.3.0'
}
}

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

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

有人请告诉我我在这里做错了什么吗？

Answer 1

由于我认为您同时使用了新AndroidX和旧Android Support的库，而错误提示了androidx.core.app.CoreComponentFactory和android.support.v4.app.CoreComponentFactory，因此请在gradle.properties：

android.useAndroidX=true
android.enableJetifier=true

这应该解决这些依赖关系冲突。希望对您有帮助！
