Question

我在运行该应用时出现此错误：

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:6:5-30:19 to override.

当我在清单tools:replace="android:appComponentFactory"元素中添加<application>时，现在出现此错误：

Manifest merger failed with multiple errors, see logs

我不知道这意味着什么。.我只是想在我的应用程序中提供一些介绍，以便首次为我们的应用程序用户提供指南。

我有以下依赖性：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    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.android.support:support-v4:28.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.github.razerdp:AnimatedPieView:1.2.4'
    implementation 'org.jetbrains:annotations-java5:15.0'
    implementation 'com.rengwuxian.materialedittext:library:2.1.4'
    debugImplementation 'com.amitshekhar.android:debug-db:1.0.5'
    implementation 'com.github.AppIntro:AppIntro:v5.1.0'
}

这些清单代码：

<?xml version="1.0" encoding="utf-8"?>

    xmlns:tools="http://schemas.android.com/tools"

        <activity android:name=".Intro"
            android:screenOrientation="portrait"/>

我不知道这些错误是什么和我是我们应用程序的首次用户使用此Intro类：

第1步：在gradle.properties中添加以下代码段

android.enableJetifier=true 
android.useAndroidX=true

第2步：在dependencies-Module:app文件的build.gradle部分中的以下代码段中添加

implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0-alpha04'

希望这会对您有所帮助。
