## 추가 구성 단계

### 다른 HMS 푸시 라이브러리 또는 자체 `HmsMessageService` 클래스와의 호환성

다음의 경우 필요합니다:

* OneSignal 외에 앱에 다른 HMS 푸시 SDK/라이브러리가 있는 경우
* 자체 `HmsMessageService`가 있는 경우

<Accordion title="자세한 내용...">
  아직 없는 경우 `HmsMessageService`에서 확장하는 클래스를 생성하고 다음 메서드를 추가합니다.

  <Warning>
    이미 `HmsMessageService`를 확장하는 클래스가 있는 경우 다른 클래스를 생성하는 대신 두 개의 새로운 `OneSignalHmsEventBridge` 라인을 추가하세요.
  </Warning>

  ```java Java theme={null}
  public class YourHmsMessageService extends HmsMessageService {
    public void onNewToken(String token) {
        // ...
        // Forward event on to OneSignal SDK
        OneSignalHmsEventBridge.onNewToken(this, token);
    }

    @Override
    public void onMessageReceived(RemoteMessage message) {
        // ...
        // Forward event on to OneSignal SDK
        OneSignalHmsEventBridge.onMessageReceived(this, message);
    }
  }
  ```

  이는 `OneSignalHmsEventBridge`를 통해 `onNewToken` 및 `onMessageReceived`를 OneSignal로 전달하기 위한 것입니다.

  이전에 `HmsMessageService`를 확장하는 클래스가 없었다면 `<application>` 태그 아래의 `AndroidManifest.xml`에 추가해야 합니다.

  ```xml AndroidManifest.xml theme={null}
  <application>
      ...

      <!--
        Ensure you only have one intent-filter for "com.huawei.push.action.MESSAGING_EVENT".
        HMS only supports one per app.
      -->
      <service
          android:name=".YourHmsMessageService"
          android:exported="false">
          <intent-filter>
              <action android:name="com.huawei.push.action.MESSAGING_EVENT" />
          </intent-filter>
      </service>

      ...
  </application>
  ```
</Accordion>

### Huawei AppGallery 빌드에 대한 Google 라이브러리 생략 (선택 사항)

<Accordion title="자세한 내용...">
  <Tabs>
    <Tab title="옵션 1">
      앱이 Huawei AppGallery에서만 사용 가능하고 OneSignal이 포함하는 Google 관련 의존성을 생략하려는 경우 `app/build.gradle`에서 `implementation`과 함께 `exclude`를 사용할 수 있습니다.

      <CodeGroup>
        ```groovy app/build.gradle theme={null}
        implementation('com.onesignal:OneSignal:[5.4.0, 5.99.99]') {
            exclude group: 'com.google.android.gms'
            exclude group: 'com.google.firebase'
        }
        ```
      </CodeGroup>
    </Tab>

    <Tab title="옵션 2">
      앱이 Google Play 스토어와 Huawei AppGallery 모두에 사용되고 APK를 더 작게 만들기 위해 포함할 라이브러리를 선택적으로 지정하려는 경우 buildTypes 또는 variants를 기반으로 의존성을 추가할 수 있습니다. 예시:

      <CodeGroup>
        ```groovy app/build.gradle theme={null}
        android {
          // ...
           buildTypes {
               debug {
               }
               release {
               }
               // **** Add your custom hauwei buildType here
               huawei {
               }
           }
        }

        dependencies {
        // \*\*\*\* Use the full OneSignal dependencies for Google Play Store builds
        debugImplementation 'com.onesignal:OneSignal:[5.0.0, 5.99.99]'
        releaseImplementation 'com.onesignal:OneSignal:[5.0.0, 5.99.99]'

            // **** Only include hms:push for your Huawei AppGallery builds.
            huaweiImplementation 'com.huawei.hms:push:6.3.0.304'
            // Omit Google / Firebase libraries for Huawei builds.
            huaweiImplementation('com.onesignal:OneSignal:[5.0.0, 5.99.99]') {
                exclude group: 'com.google.android.gms'
                exclude group: 'com.google.firebase'
            }

        }

        ```
      </CodeGroup>
    </Tab>
  </Tabs>
</Accordion>

### FCM보다 HMS 우선 사용 (선택 사항)

<Accordion title="자세한 내용...">
  ***위에서 Huawei AppGallery 빌드에 대해 [Google 라이브러리를 생략](./huawei-sdk-setup#omit-google-libraries-for-huawei-appgallery-builds-optional)한 경우 이 단계는 적용되지 않습니다.***

  기본적으로 OneSignal은 앱에 둘 다 포함된 경우 HMS보다 FCM 사용을 선호합니다. 대신 HMS를 선호하도록 변경하려면 `AndroidManifest.xml`에 다음을 추가할 수 있습니다:

  <CodeGroup>
    ```xml xml theme={null}
    <application>
            ...
            <meta-data android:name="com.onesignal.preferHMS" android:value="true"/>
            ...
     </application>
    ```
  </CodeGroup>
</Accordion>

***

## Huawei 문제 해결

테스트하는 동안 [OneSignal setLogLevel 메서드](./mobile-sdk-reference#setloglevel)를 VERBOSE로 설정해야 합니다.

로그를 확인하여 발생하는 오류와 [Huawei 일반 오류 코드](https://developer.huawei.com/consumer/en/doc/development/HMS-2-References/hmssdk_huaweipush_api_reference_errorcode)를 확인하세요.

<Accordion title="6003 오류">
  OneSignal SDK로 Huawei `pushToken`을 등록할 때 `6003` 오류를 방지하려면 디버그 또는 릴리스 키스토어 서명을 생성해야 할 수 있습니다(올바른 앱 빌드 경로 `debug` 또는 `release` 선택). ["서명 구성" 섹션](https://developer.huawei.com/consumer/en/doc/HMS-Guides/Preparations#h2-1584707362385)을 참조하세요.
</Accordion>

<Accordion title="notification_types: -25">
  `"notification_types":-25`는 OneSignal이 푸시 토큰을 얻기 위해 Huawei의 HMS로부터 응답을 기다리다가 시간 초과되었음을 의미합니다. 이는 OneSignal 대신 다른 제3자 HMS 푸시 SDK 또는 자체 HmsMessageService가 이 이벤트를 받기 때문일 가능성이 높습니다.

  이 경우 [이를 확인하고 이벤트를 전달하는 방법에 대한 단계](#compatibility-with-other-hms-push-libraries-or-your-own-hmsmessageservice-class)를 검토하세요.
</Accordion>

<Accordion title="notification_types: -28">
  이는 푸시에 필요한 클래스가 앱에서 누락되었음을 의미합니다. `build.gradle`에 `com.huawei.hms:push`만 있으면 이 특정 오류가 더 이상 발생하지 않습니다. 그러나 공격적인 Proguard 또는 R8 설정이 있는 경우 문제가 발생할 수 있습니다. 문제의 근본 원인인지 확인하기 위해 `minifyEnabled`를 일시적으로 끄는 것이 좋습니다.

  또한 다른 HMS 라이브러리의 주요 릴리스 버전을 혼합해서는 안 됩니다. 4 또는 5 중 하나로 시작하세요. 3에서 5까지 혼합하지 않도록 주의하세요. 이는 다른 오류를 생성합니다.
</Accordion>

<Accordion title="Huawei 푸시 토큰을 가져오는 오류">
  ```
  E/OneSignal: HMS ApiException getting Huawei push token!
      com.huawei.hms.common.ApiException: -5: Core error
  ```

  Proguard 또는 R8 규칙이 올바르게 설정되어 있는지 확인하세요. 관련이 있는지 확인하기 위해 일시적으로 비활성화할 수 있습니다. Proguard 또는 R8을 비활성화한 후 문제가 해결되면 이 가이드를 따라 다시 활성화할 수 있습니다. ["서명 구성" 섹션](https://developer.huawei.com/consumer/en/doc/HMS-Guides/Preparations#h2-1584707362385)을 참조하세요.
</Accordion>

### Send an in-app message

[In-app messages](/docs/en/in-app-messages-setup) let you communicate with users while they are using your app.

<Steps>
  <Step title="Close or background your app on the device.">
    This is because users must meet the in-app audience criteria *before* a new session starts. In OneSignal, a new session starts when the user opens your app after it has been in the background or closed for at least 30 seconds. For more details, see our guide on [how in-app messages are displayed](/docs/en/in-app-messages-setup#how-are-iams-displayed%3F).
  </Step>

  <Step title="Create an in-app message.">
    * In your OneSignal dashboard, navigate to **Messages > In-App > New In-App**.
    * Find and select the **Welcome** message.
    * Set your Audience as the **Test Users** segment we used previously.

## User identification

Previously, we demonstrated how to create mobile [Subscriptions](/docs/en/subscriptions). Now we'll expand to identifying [Users](/docs/en/users) across all their subscriptions (including push, email, and SMS) using the OneSignal SDK. We'll cover External IDs, tags, multi-channel subscriptions, privacy, and event tracking to help you unify and engage users across platforms.

### Assign External ID

Use an External ID to identify users consistently across devices, email addresses, and phone numbers using your backend's user identifier. This ensures your messaging stays unified across channels and 3rd party systems (especially important for [Integrations](/docs/en/integrations)).

Set the External ID with our SDK's [`login` method](/docs/en/mobile-sdk-reference#login-external-id) each time they are identified by your app.

<Note>
  OneSignal generates unique read-only IDs for subscriptions (Subscription ID) and users (OneSignal ID).

  As users download your app on different devices, subscribe to your website, and/or provide you email addresses and phone numbers outside of your app, new subscriptions will be created.

  Setting the External ID via our SDK is highly recommended to identify users across all their subscriptions, regardless of how they are created.
</Note>

### Add Tags

[Tags](/docs/en/add-user-data-tags) are key-value pairs of string data you can use to store user properties (like `username`, `role`, or preferences) and events (like `purchase_date`, `game_level`, or user interactions). Tags power advanced [Message Personalization](/docs/en/message-personalization) and [Segmentation](/docs/en/segmentation) allowing for more advanced use cases.

Set tags with our SDK [`addTag` and `addTags` methods](/docs/en/mobile-sdk-reference#data-tags) as events occur in your app.

In this example, the user reached level 6 identifiable by the tag called `current_level` set to a value of `6`.

<Frame caption="A user profile in OneSignal with a tag called &#x22;current_level&#x22; set to &#x22;6&#x22;">
  <img src="https://mintcdn.com/onesignal/4HyuQPBpu-4xjmQC/images/docs/d4674261847231079fecc176ba88065409c90943e3854b9df200457325a0aed4-Screenshot_2025-03-18_at_14.47.25.png?fit=max&auto=format&n=4HyuQPBpu-4xjmQC&q=85&s=91083bf83a4c03ea40d485b23f072259" width="1380" height="941" data-path="images/docs/d4674261847231079fecc176ba88065409c90943e3854b9df200457325a0aed4-Screenshot_2025-03-18_at_14.47.25.png" />
</Frame>

We can create a segment of users that have a level of between 5 and 10, and use that to send targeted and personalized messages:

### Add email and/or SMS subscriptions

Earlier we saw how our SDK creates mobile subscriptions to send push and in-app messages. You can also reach users through emails and SMS channels by creating the corresponding subscriptions.

* Use the [`addEmail` method](/docs/en/mobile-sdk-reference#addemail-%2C-removeemail) to create email subscriptions.
* Use the [`addSms` method](/docs/en/mobile-sdk-reference#addsms-%2C-removesms) to create SMS subscriptions.

If the email address and/or phone number already exist in the OneSignal app, the SDK will add it to the existing user, it will not create duplicates.

You can view unified users via **Audience > Users** in the dashboard or with the [View user API](/reference/view-user).

<Frame caption="A user profile with push, email, and SMS subscriptions unified by External ID">
  <img src="https://mintcdn.com/onesignal/56ctKxZSV4m5VEkn/images/docs/b1cf9999d41da6e4ce333e1126612529b85eac47447bb0b434418d082f595acd-Screenshot_2025-03-18_at_14.43.46.png?fit=max&auto=format&n=56ctKxZSV4m5VEkn&q=85&s=7c3885b66e44e097fa0ed7c47f27c911" width="1506" height="848" data-path="images/docs/b1cf9999d41da6e4ce333e1126612529b85eac47447bb0b434418d082f595acd-Screenshot_2025-03-18_at_14.43.46.png" />
</Frame>

<Note>
  Best practices for multi-channel communication

  * Obtain explicit consent before adding email or SMS subscriptions.
  * Explain the benefits of each communication channel to users.
  * Provide channel preferences so users can select which channels they prefer.
</Note>

***

### Privacy & user consent

To control when OneSignal collects user data, use the SDK's consent gating methods:

* [`setConsentRequired(true)`](/docs/en/mobile-sdk-reference#setconsentrequired): Prevents data collection until consent is given.
* [`setConsentGiven(true)`](/docs/en/mobile-sdk-reference#setconsentgiven): Enables data collection once consent is granted.

See our Privacy & security docs for more on:

* [Data collected by the SDK](/docs/en/data-collected-by-the-onesignal-sdk)
* [Handling personal data](/docs/en/handling-personal-data)

***

## Prompt for push permissions

Instead of calling `requestPermission()` immediately on app open, take a more strategic approach. Use an in-app message to explain the value of push notifications before requesting permission.

For best practices and implementation details, see our [Prompt for push permissions](/docs/en/prompt-for-push-permissions) guide.

***

## Listen to push, user, and in-app events

Use SDK listeners to react to user actions and state changes.

The SDK provides several event listeners for you to hook into. See our [SDK reference guide](/docs/en/mobile-sdk-reference) for more details.

### Push notification events

* [`addClickListener()`](/docs/en/mobile-sdk-reference#addclicklistener-push): Detect when a notification is tapped. Helpful for [Deep Linking](/docs/en/deep-linking).
* [`addForegroundLifecycleListener()`](/docs/en/mobile-sdk-reference#addforegroundlifecyclelistener-push): Control how notifications behave in foreground.

For full customization, see [Mobile Service Extensions](/docs/en/service-extensions).

### User state changes

* [`addObserver()` for user state](/docs/en/mobile-sdk-reference#addobserver-user-state): Detect when the External ID is set.
* [`addPermissionObserver()`](/docs/en/mobile-sdk-reference#addpermissionobserver-push): Track the user's specific interaction with the native push permission prompt.
* [`addObserver()` for push subscription](/docs/en/mobile-sdk-reference#addobserver-push-subscription-changes): Track when the push subscription status changes.

### In-app message events

* [`addClickListener()`](/docs/en/mobile-sdk-reference#addclicklistener-in-app): Handle in-app click actions. Ideal for deep linking or tracking events.
* [`addLifecycleListener()`](/docs/en/mobile-sdk-reference#addclicklistener-in-app): Track full lifecycle of in-app messages (shown, clicked, dismissed, etc.).
