Google Play Core 库概览

本页将介绍 Google Play Core 库以及如何将其添加到您的项目中。

Google Play Core 库是您的应用与 Google Play 商店的运行时接口。您可以执行的操作包括：

Play Core 库支持 Java、原生代码和 Unity。如需详细了解最新版本，请参阅版本说明。

从 Play Core Java 和 Kotlin 库迁移

Play Core Java 和 Kotlin 库已拆分为多个基于功能的 Android 库。这样可以缩减添加到应用的 Play Core 库的大小，并缩短各个功能的发布周期。

迁移后，各项功能的行为均与先前保持一致。唯一显著的变化是，新版本采用了 Google Play 服务的 Tasks API。

您可以使用下面的列表迁移到新库，并从新功能和 bug 修复中获益。如果您使用多个 Play 功能，您还可以一次性在 build.gradle 文件中导入多个库。

常见的迁移步骤

将 Tasks 对象的所有现有 import 语句从 import com.google.android.play.core.tasks.*; 更新为 import com.google.android.gms.tasks.*;。更新后，所有类名称均保持不变。
移除 build.gradle 文件中导入的任何旧版 Play Core 库。

集成 Play Asset Delivery 库

Groovy

// In your app's build.gradle file:
...
dependencies {
    // This dependency is downloaded from the Google's Maven repository.
    // So, make sure you also include that repository in your project's build.gradle file.
    implementation 'com.google.android.play:asset-delivery:2.3.0'

    // For Kotlin users also add the Kotlin extensions library for Play Asset Delivery:
    implementation 'com.google.android.play:asset-delivery-ktx:2.3.0'
    ...
}

Kotlin

// In your app's build.gradle.kts file:
...
dependencies {
    // This dependency is downloaded from the Google's Maven repository.
    // So, make sure you also include that repository in your project's build.gradle file.
    implementation("com.google.android.play:asset-delivery:2.3.0")

    // For Kotlin users also import the Kotlin extensions library for Play Asset Delivery:
    implementation("com.google.android.play:asset-delivery-ktx:2.3.0")
    ...
}

集成 Play Feature Delivery 库

Groovy

// In your app's build.gradle file:
...
dependencies {
    // This dependency is downloaded from the Google's Maven repository.
    // So, make sure you also include that repository in your project's build.gradle file.
    implementation 'com.google.android.play:feature-delivery:2.1.0'

    // For Kotlin users, also add the Kotlin extensions library for Play Feature Delivery:
    implementation 'com.google.android.play:feature-delivery-ktx:2.1.0'
    ...
}

Kotlin

// In your app's build.gradle.kts file:
...
dependencies {
    // This dependency is downloaded from the Google's Maven repository.
    // Make sure you also include that repository in your project's build.gradle file.
    implementation("com.google.android.play:feature-delivery:2.1.0")

    // For Kotlin users, also import the Kotlin extensions library for Play Feature Delivery:
    implementation("com.google.android.play:feature-delivery-ktx:2.1.0")
    ...
}

集成 Play 应用内评价库

Groovy

// In your app's build.gradle file:
...
dependencies {
    // This dependency is downloaded from the Google's Maven repository.
    // Make sure you also include that repository in your project's build.gradle file.
    implementation 'com.google.android.play:review:2.0.2'

    // For Kotlin users, also add the Kotlin extensions library for Play In-App Review:
    implementation 'com.google.android.play:review-ktx:2.0.2'
    ...
}

Kotlin

// In your app's build.gradle.kts file:
...
dependencies {
    // This dependency is downloaded from the Google's Maven repository.
    // Make sure you also include that repository in your project's build.gradle file.
    implementation("com.google.android.play:review:2.0.2")

    // For Kotlin users, also import the Kotlin extensions library for Play In-App Review:
    implementation("com.google.android.play:review-ktx:2.0.2")
    ...
}

集成 Play 应用内更新库

Groovy

// In your app's build.gradle file:
...
dependencies {
    // This dependency is downloaded from the Google's Maven repository.
    // Make sure you also include that repository in your project's build.gradle file.
    implementation 'com.google.android.play:app-update:2.1.0'

    // For Kotlin users, also add the Kotlin extensions library for Play In-App Update:
    implementation 'com.google.android.play:app-update-ktx:2.1.0'
    ...
}

Kotlin

// In your app's build.gradle.kts file:
...
