Google Play Core 库概览

本页面介绍了 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。您可以执行以下操作：

Play Core 库提供 Java、原生和 Unity 版本。如需了解最新版本，请参阅版本说明。

从 Play Core Java 和 Kotlin 库迁移

Play Core Java 和 Kotlin 库已分拆成多个按功能划分的 Android 库。这减小了 Play Core 库添加到您应用中的大小，并可加快单个功能的发布周期。

在此次迁移中，每个功能的行为保持一致，唯一值得注意的变化是新版本采用了 Google Play 服务 Task API。

使用以下列表迁移到新库，并从新功能和错误修复中获益。如果您使用多个 Play 功能，您可以一次性在 build.gradle 文件中导入多个库。

常见迁移步骤

  1. 将 Task 对象的任何现有 import 语句从 import com.google.android.play.core.tasks.*; 更新为 import com.google.android.gms.tasks.*;。所有类名称保持不变。
  2. 从您的 build.gradle 文件中移除任何旧的 Play Core 库的导入。

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

    ...
}

Kotlin

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

    // 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:
...

    // 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 import the Kotlin extensions library for Play In-App Update:
    implementation("com.google.android.play:app-update-ktx:2.1.0")
    ...
}
