Google Play Core Library 總覽

本資訊頁面說明 Google Play Core Library，以及如何將這些程式庫新增至專案。

Google Play Core Library 是應用程式與 Google Play 商店之間的執行階段介面。您可以採取下列幾項行動：

Play Core Library 提供 Java、原生和 Unity 版本。如要進一步瞭解最新版本，請參閱版本資訊。

從 Play Core Java 和 Kotlin 程式庫遷移

Play Core Java 和 Kotlin 程式庫已分割為多個提供個別功能的 Android 程式庫。這麼做可縮減 Play Core Library 加入應用程式的大小，並縮短個別功能的發布週期。

在這項遷移作業中，各項功能的行為皆保持一致，唯一的差別在於新版採用了 Google Play 服務的 Task API。

請使用下方清單遷移至新的程式庫，獲取新功能和錯誤修正帶來的優勢。如果您要使用多項 Play 功能，則可以直接在 build.gradle 檔案中一次匯入多個程式庫。

常見的遷移步驟

  1. 將 Task 物件的任何現有匯入陳述式從 import com.google.android.play.core.tasks.*; 更新為 import com.google.android.gms.tasks.*;。所有類別名稱皆維持不變。
  2. 移除 build.gradle 檔案中所有的舊版 Play Core Library 匯入作業。

整合 Play Asset Delivery 程式庫

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:2.2.2'

    // For Kotlin users also add the Kotlin extensions library for Play Asset Delivery:
    implementation 'com.google.android.play:asset-delivery-ktx:2.2.2'
    ...
}

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:2.2.2")

    // For Kotlin users also import the Kotlin extensions library for Play Asset Delivery:

    // Make sure you also include that repository in your project's build.gradle file.
    implementation 'com.google.android.play:review:2.0.1'

    // For Kotlin users, also add the Kotlin extensions library for Play In-App Review:
    implementation 'com.google.android.play:review-ktx:2.0.1'
    ...
}

Kotlin

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

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:
