Android gradle 中的清单合并失败错误

Question

我收到manifest merger failed错误。 我已经尝试了大多数建议的方法来修复以下具有依赖性的错误，但无法解决。

下面是我的 Gradle 文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.plainnotes"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        vectorDrawables.useSupportLibrary = true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    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'
    // additional libraries
    implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0-alpha1'
    implementation 'androidx.room:room-runtime:2.1.0-alpha03'
    annotationProcessor "androidx.room:room-compiler:2.1.0-alpha03"
    implementation 'com.jakewharton:butterknife:10.0.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:10.0.0'
}

这是我收到的错误消息

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:5:5-22:19 to override.

Answer 1

我有一个类似的问题。 gradle.properties 文件中的两行：

android.useAndroidX=true
android.enableJetifier=true

并将其添加到清单中

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools"
package="your.package.uri">

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    tools:replace="android:appComponentFactory"
    android:appComponentFactory="androidx">

Answer 2

这是因为您使用的是不同的 android库。 对所有库的 AndroidX 包进行重构

有了这个

implementation fileTree(include: ['*.jar'], dir: 'libs')
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'

// additional libraries
implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0-alpha1'
implementation 'androidx.room:room-runtime:2.1.0-alpha03'
annotationProcessor "androidx.room:room-compiler:2.1.0-alpha03"
implementation 'com.jakewharton:butterknife:10.0.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:10.0.0'

对此

//Android support libraries.
    implementation 'androidx.appcompat:appcompat:1.0.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'com.google.android.material:material:1.0.0'
    implementation 'androidx.recyclerview:recyclerview:1.0.0'

    implementation 'androidx.cardview:cardview:1.0.0'
    implementation 'androidx.multidex:multidex:2.0.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha2' 

由于支持库和 AndroidX 库是不同的。 所以只使用一种类型的库。

您正在将新的 androidx 包与旧版本的 android 支持库混合使用。 您可以在以下链接https://developer.android.com/jetpack/androidx/migrate上找到指南和新的 androidx 包
