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但无法解决的错误。

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

这是因为您正在为 android 使用 不同的库。对所有库的 AndroidX 包进行了重构

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'

到这里

//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' 

支持库和 AndroidX 库是不同的。所以只使用一种类型的库。

我遇到了类似的问题。 gradle.properties 文件中有两行：

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">

您正在将新的 androidx 包与旧版本的 android 支持库混合。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
