Android Architecture Components(Android 架构组件)依赖

AndroidX

Arch 某些组件改为androidx,目前已经发布一些预览版,查看详情

kotlin

kotlin支持androidx依赖,只需后缀"-ktx":

普通依赖:

implementation "androidx.lifecycle:lifecycle-viewmodel:$lifecycle_version" // use -ktx for Kotlin

kotlin依赖:

implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"

添加Google仓库

在你项目的build.gradle文件中添加:

allprojects {
    repositories {
        jcenter()
        google()
    }
}

然后打开你module下的build.gradle文件:

Lifecycle

依赖 Lifecycle, 包括LiveData 和ViewModel 两大组件

dependencies {
    def lifecycle_version = "1.1.1"

    // ViewModel and LiveData
    implementation "android.arch.lifecycle:extensions:$lifecycle_version"
    // alternatively - just ViewModel
    implementation "android.arch.lifecycle:viewmodel:$lifecycle_version" // use -ktx for Kotlin
    // alternatively - just LiveData
    implementation "android.arch.lifecycle:livedata:$lifecycle_version"
    // alternatively - Lifecycles only (no ViewModel or LiveData).
    //     Support library depends on this lightweight import
    implementation "android.arch.lifecycle:runtime:$lifecycle_version"

    annotationProcessor "android.arch.lifecycle:compiler:$lifecycle_version"
    // alternately - if using Java8, use the following instead of compiler
    implementation "android.arch.lifecycle:common-java8:$lifecycle_version"

    // optional - ReactiveStreams support for LiveData
    implementation "android.arch.lifecycle:reactivestreams:$lifecycle_version"

    // optional - Test helpers for LiveData
    testImplementation "android.arch.core:core-testing:$lifecycle_version"
}

AndroidX

dependencies {
    def lifecycle_version = "2.0.0-alpha1"

    // ViewModel and LiveData
    implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_version"
    // alternatively - just ViewModel
    implementation "androidx.lifecycle:lifecycle-viewmodel:$lifecycle_version" // use -ktx for Kotlin
    // alternatively - just LiveData
    implementation "androidx.lifecycle:lifecycle-livedata:$lifecycle_version"
    // alternatively - Lifecycles only (no ViewModel or LiveData). Some UI
    //     AndroidX libraries use this lightweight import for Lifecycle
    implementation "androidx.lifecycle:lifecycle-runtime:$lifecycle_version"

    annotationProcessor "androidx.lifecycle:lifecycle-compiler:$lifecycle_version"
    // alternately - if using Java8, use the following instead of lifecycle-compiler
    implementation "androidx.lifecycle:lifecycle-common-java8:$lifecycle_version"

    // optional - ReactiveStreams support for LiveData
    implementation "androidx.lifecycle:lifecycle-reactivestreams:$lifecycle_version" // use -ktx for Kotlin

    // optional - Test helpers for LiveData
    testImplementation "androidx.arch.core:core-testing:$lifecycle_version"
}

Room

依赖 Room, 包括testing Room migrations 和Room RxJava 两大模块

dependencies {
    def room_version = "1.1.0"

    implementation "android.arch.persistence.room:runtime:$room_version"
    annotationProcessor "android.arch.persistence.room:compiler:$room_version"

    // optional - RxJava support for Room
    implementation "android.arch.persistence.room:rxjava2:$room_version"

    // optional - Guava support for Room, including Optional and ListenableFuture
    implementation "android.arch.persistence.room:guava:$room_version"

    // Test helpers
    testImplementation "android.arch.persistence.room:testing:$room_version"
}

AndroidX

dependencies {
    def room_version = "2.0.0-alpha1"

    implementation "androidx.room:room-runtime:$room_version"
    annotationProcessor "androidx.room:room-compiler:$room_version"

    // optional - RxJava support for Room
    implementation "androidx.room:room-rxjava2:$room_version"

    // optional - Guava support for Room, including Optional and ListenableFuture
    implementation "androidx.room:room-guava:$room_version"

    // Test helpers
    testImplementation "androidx.room:room-testing:$room_version"
}

Paging

dependencies {
    def paging_version = "1.0.0"

    implementation "android.arch.paging:runtime:$paging_version"

    // alternatively - without Android dependencies for testing
    testImplementation "android.arch.paging:common:$paging_version"

    // optional - RxJava support, currently in alpha
    implementation "android.arch.paging:rxjava2:1.0.0-alpha1"
}

AndroidX

dependencies {
    def paging_version = "2.0.0-alpha1"

    implementation "androidx.paging:paging-runtime:$paging_version"

    // alternatively - without Android dependencies for testing
    testImplementation "androidx.paging:paging-common:$paging_version"

    // optional - RxJava support
    implementation "androidx.paging:paging-rxjava2:1.0.0-alpha1"
}

Navigation

AndroidX版本目前暂无

dependencies {
    def nav_version = "1.0.0-alpha01"

    implementation "android.arch.navigation:navigation-fragment:$nav_version" // use -ktx for Kotlin
    implementation "android.arch.navigation:navigation-ui:$nav_version" // use -ktx for Kotlin

    // optional - Test helpers
    androidTestImplementation "android.arch.navigation:navigation-testing:$nav_version" // use -ktx for Kotlin
}

Safe args

首先打开项目的build.gradle文件添加:

buildscript {
    repositories {
        google()
    }
    dependencies {
        classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0-alpha01"
    }
}

打开module的build.gradle文件添加:

apply plugin: "androidx.navigation.safeargs"

WorkManager

AndroidX版本暂无

dependencies {
    def work_version = "1.0.0-alpha01"

    implementation "android.arch.work:work-runtime:$work_version" // use -ktx for Kotlin

    // optional - Firebase JobDispatcher support
    implementation "android.arch.work:work-firebase:$work_version"

    // optional - Test helpers
    androidTestImplementation "android.arch.work:work-testing:$work_version"
}
