【问题描述】：

我是 Android 开发的新手，但我一生都无法弄清楚这个错误，我尝试了解决方案 here 和 here。我仍然无法让这个应用程序运行。

错误是

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:5:5-19:19 to override.

这是我的 build.gradle 文件

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "n8tivedesigns.com.full_rack_mobile"
        minSdkVersion 19
        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'
    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.android.gms:play-services-maps:17.0.0'
}

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '28.0.0'
            }
        }
    }
}

非常感谢任何帮助。

【问题讨论】：

你添加了tools:replace="android:appComponentFactory"，但什么也没发生？
我做了，上面写着The prefix "tools" for attribute "tools:replace" associated with an element type "application" is not bound.
所以试试下面我的回答，看看是否有帮助
这是什么时候开始的？你做了什么？
@Shermano 我添加了它并删除了那个错误，但添加了Error: tools:replace specified at line:6 for attribute android:appComponentFactory, but no new value specified app main manifest (this file), line 5

标签： android gradle kotlin android-gradle-plugin

【解决方案1】：

在 AndroidManifest.xml 的应用标签上添加tools:replace="android:appComponentFactory" 并将xmlns:tools="http://schemas.android.com/tools" 添加到您的清单标签

示例：

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        package="(..)">

<application
        android:name=".YourApp"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@drawable/ic_launcher_rounded"
        android:supportsRtl="true"
        tools:replace="android:appComponentFactory"
