이 가이드에서는 Kotlin 또는 자바를 사용하여 앱에 인앱 리뷰를 통합하는 방법을 설명합니다. 네이티브 코드, Unity 또는 Unreal Engine을 사용하는 경우 별도의 통합 가이드를 참고하세요.
개발 환경 설정
Play In-App Review 라이브러리는 Google Play Core 라이브러리의 일부입니다.
Play In-App Review 라이브러리를 통합하려면 다음 Gradle 종속 항목을 포함하세요.
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: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.// So, 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")...}
인앱 리뷰를 요청하는 경우에 관한 가이드라인에 따라 앱의 사용자 플로우에서 적절한 지점을 결정하여 사용자에게 리뷰를 요청하는 메시지를 표시합니다 (예를 들어 게임에서 사용자가 레벨을 완료할 때). 앱이 이러한 지점 중 하나에 도달하면 ReviewManager 인스턴스를 사용하여 요청 작업을 생성합니다. 성공하면 API는 인앱 리뷰 흐름을 시작하는 데 필요한 ReviewInfo 객체를 반환합니다.
Kotlin
valrequest=manager.requestReviewFlow()request.addOnCompleteListener{task->if(task.isSuccessful){// We got the ReviewInfo objectvalreviewInfo=task.result}else{// There was some problem, log or handle the error code.@ReviewErrorCodevalreviewErrorCode=(task.getException()asReviewException).errorCode}}
자바
ReviewManagermanager=ReviewManagerFactory.create(this);Task<ReviewInfo>request=manager.requestReviewFlow();request.addOnCompleteListener(task->{if(task.isSuccessful()){// We can get the ReviewInfo objectReviewInforeviewInfo=task.getResult();}else{// There was some problem, log or handle the error code.@ReviewErrorCodeintreviewErrorCode=((ReviewException)task.getException()).getErrorCode();}});
인앱 리뷰 흐름 시작
ReviewInfo 인스턴스를 사용하여 인앱 리뷰 흐름을 시작합니다. 앱은 사용자가 인앱 리뷰 흐름을 완료할 때까지 기다려야 일반적인 사용자 흐름 (예: 다음 레벨로 진행)을 계속할 수 있습니다.
Kotlin
valflow=manager.launchReviewFlow(activity,reviewInfo)flow.addOnCompleteListener{_->// The flow has finished. The API does not indicate whether the user// reviewed or not, or even whether the review dialog was shown. Thus, no// matter the result, we continue our app flow.}
자바
Task<Void>flow=manager.launchReviewFlow(activity,reviewInfo);flow.addOnCompleteListener(task->{// The flow has finished. The API does not indicate whether the user// reviewed or not, or even whether the review dialog was shown. Thus, no// matter the result, we continue our app flow.});

There are separate integration guides if you are using [native\ncode](/guide/playcore/in-app-review/native), [Unity](/guide/playcore/in-app-review/unity) or [Unreal Engine](/guide/playcore/in-app-review/unreal-engine).\n\nSet up your development environment\n\nThe Play In-App Review Library is a part of the [Google Play Core libraries](/guide/playcore).\nInclude the following Gradle dependency to integrate the Play In-App Review\nLibrary. \n\nGroovy \n\n```groovy\n// In your app's build.gradle file:\n...\ndependencies {\n // This dependency is downloaded from the /studio/build/dependencies#google-maven.\n // So, make sure you also include that repository in your project's build.gradle file.\n implementation 'com.google.android.play:review:2.0.2'\n\n // For Kotlin users also add the Kotlin extensions library for Play In-App Review:\n implementation 'com.google.android.play:review-ktx:2.0.2'\n ...\n}\n```\n\nKotlin \n\n```kotlin\n// In your app's build.gradle.kts file:\n...\ndependencies {\n // This dependency is downloaded from the /studio/build/dependencies#google-maven.\n // So, make sure you also include that repository in your project's build.gradle file.\n implementation(\"com.google.android.play:review:2.0.2\")\n\n // For Kotlin users also import the Kotlin extensions library for Play In-App Review:\n implementation(\"com.google.android.play:review-ktx:2.0.2\")\n ...\n}\n```\n\nCreate the ReviewManager\n\nThe [`ReviewManager`](/reference/com/google/android/play/core/review/ReviewManager) is the interface that lets your app start an in-app\nreview flow. Obtain it by creating an instance using the\n[`ReviewManagerFactory`](/reference/com/google/android/play/core/review/ReviewManagerFactory). \n\nKotlin \n\n```kotlin\nval manager = ReviewManagerFactory.create(context)\n```\n\nJava \n\n```java\nReviewManager manager = ReviewManagerFactory.create(context)\n```\n\nRequest a ReviewInfo object\n\nFollow the guidance about [when to request in-app reviews](/guide/playcore/in-app-review#when-to-request) to determine good\npoints in your app's user flow to prompt the user for a review (for example,\nwhen the user completes a level in a game). When your app reaches one of these\npoints, use the [`ReviewManager`](/reference/com/google/android/play/core/review/ReviewManager) instance to create a request task. If\nsuccessful, the API returns the [`ReviewInfo`](/reference/com/google/android/play/core/review/ReviewInfo) object needed to start the\nin-app review flow. \n\nKotlin \n\n```kotlin\nval request = manager.requestReviewFlow()\nrequest.addOnCompleteListener { task -\u003e\n if (task.isSuccessful) {\n // We got the ReviewInfo object\n val reviewInfo = task.result\n } else {\n // There was some problem, log or handle the error code.\n @ReviewErrorCode val reviewErrorCode = (task.getException() as ReviewException).errorCode\n }\n}\n```\n\nJava \n\n```java\nReviewManager manager = ReviewManagerFactory.create(this);\nTask\u003cReviewInfo\u003e request = manager.requestReviewFlow();\nrequest.addOnCompleteListener(task -\u003e {\n if (task.isSuccessful()) {\n // We can get the ReviewInfo object\n ReviewInfo reviewInfo = task.getResult();\n } else {\n // There was some problem, log or handle the error code.\n @ReviewErrorCode int reviewErrorCode = ((ReviewException) task.getException()).getErrorCode();\n }\n});\n```\n| **Note:** The [`ReviewInfo`](/reference/com/google/android/play/core/review/ReviewInfo) object is only valid for a limited amount of time. Your app should request a `ReviewInfo` object ahead of time (pre-cache) but only once you are certain that your app will launch the in-app review flow.\n\nLaunch the in-app review flow\n\nUse the [`ReviewInfo`](/reference/com/google/android/play/core/review/ReviewInfo) instance to launch the in-app review flow. Wait until\nthe user has completed the in-app review flow before your app continues its\nnormal user flow (such as advancing to the next level). \n\nKotlin \n\n```kotlin\nval flow = manager.launchReviewFlow(activity, reviewInfo)\nflow.addOnCompleteListener { _ -\u003e\n // The flow has finished. The API does not indicate whether the user\n // reviewed or not, or even whether the review dialog was shown. Thus, no\n // matter the result, we continue our app flow.\n}\n```\n\nJava \n\n```java\nTask\u003cVoid\u003e flow = manager.launchReviewFlow(activity, reviewInfo);\nflow.addOnCompleteListener(task -\u003e {\n // The flow has finished. The API does not indicate whether the user\n // reviewed or not, or even whether the review dialog was shown. Thus, no\n // matter the result, we continue our app flow.\n});\n```\n| **Important:** If an error occurs during the in-app review flow, do not inform the user or change your app's normal user flow. Continue your app's normal user flow after `onComplete` is called.\n\nNext steps\n\n[Test your app's in-app review flow](/guide/playcore/in-app-review/test) to verify that your integration is\nworking correctly."]]
