API 28 (P) 的 Android 设计支持库不起作用 [英] Android design support library for API 28 (P) not working

问题描述

我已经成功配置了 android-P SDK 环境.当我尝试使用 android 设计支持库时，我遇到了项目构建错误.项目配置为:

I've configured android-P SDK environment successfully. When I attempt to use the android design support library I face project build errors. Project configurations are:

IDE:3.2 Canary 17 目标 API:28 编译 API:28

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.app.navigationpoc"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        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 "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.0.0-alpha3'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.1'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'

    implementation 'com.android.support:design:28.0.0-alpha3'
    implementation 'com.android.support:cardview-v7:28.0.0-alpha3'
}

构建失败的错误是:

清单合并失败:属性 application@appComponentFactory值=(androidx.core.app.CoreComponentFactory) 来自[androidx.core:core:1.0.0-alpha3] AndroidManifest.xml:22:18-86 是也出现在 [com.android.support:support-compat:28.0.0-alpha3]AndroidManifest.xml:22:18-91值=(android.support.v4.app.CoreComponentFactory).建议:添加'tools:replace="android:appComponentFactory"' 到元素在 AndroidManifest.xml:6:5-40:19 覆盖.

Manifest merger failed : Attribute application@appComponentFactory value=(androidx.core.app.CoreComponentFactory) from [androidx.core:core:1.0.0-alpha3] AndroidManifest.xml:22:18-86 is also present at [com.android.support:support-compat:28.0.0-alpha3] AndroidManifest.xml:22:18-91 value=(android.support.v4.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:6:5-40:19 to override.

推荐答案

您可以使用以前的 API 包版本的 artifacts 或新的 Androidx，但不能同时使用.

You can either use the previous API packages version of artifacts or the new Androidx, never both.

如果您想使用以前的版本，请将您的依赖项替换为

If you wanna use the previous version, replace your dependencies with

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
    implementation 'com.android.support.constraint:constraint-layout:1.1.1'

    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:design:28.0.0-alpha3'
    implementation 'com.android.support:cardview-v7:28.0.0-alpha3'
}

如果您想使用 Androidx:

if you want to use Androidx:

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.0.0-alpha3'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.1'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'

    implementation 'com.google.android.material:material:1.0.0-alpha3'
    implementation 'androidx.cardview:cardview:1.0.0-alpha3'
}
