Android-更新到API 28后生成错误（清单合并失败）[重复]

Question

我正在尝试使用最新的库作为我需求的一部分。我确实将gradle版本升级到了3.1。4和所有具有匹配编译和目标SDK版本的支持库，但在构建项目时

错误：清单合并失败：属性application@appComponentFactory值=（android.support.v4.app.CoreComponentFactory）来自[com.android.support： support-compat： 28.0.0]Androidanifest.xml:22： 18-91也存在于[androidx.core： core： 1.0.0]Android<-PLHD--5/>： 18-86 value=（androidx.core.app.CoreComponentFactory）。建议：添加工具：替换="android： appComponentFactory"的元素在Androidanifest.xml:28： 5-122:19覆盖。

我的应用程序构建。gradle看起来像这样：

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

dependencies {
    classpath 'io.fabric.tools:gradle:1.+'
}
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {

    useLibrary 'org.apache.http.legacy'

}

    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),

    dirs 'libs'

}

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

我的项目级构建。格雷德尔看起来像这样

// 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
}

谁能告诉我我可能做错了什么？

Answer 1

因为我认为您正在使用新的AndroidX和旧的Android支持中的库，因为错误说明了AndroidX。果心应用程序。CoreComponentFactory和android。支持v4。应用程序。CoreComponentFactory，请在您的渐变中添加以下内容。属性：

android.useAndroidX=true
android.enableJetifier=true

这应该可以解决这些依赖冲突。希望有帮助！
