## Ek yapılandırma adımları

### Diğer HMS push kütüphaneleri veya kendi `HmsMessageService` sınıfınızla uyumluluk

Şu durumlarda gereklidir:

* Uygulamanızda OneSignal'e ek olarak başka bir HMS push SDK/Kütüphanesi var
* Kendi `HmsMessageService` sınıfınız var

<Accordion title="Daha fazla detay...">
  Henüz yoksa `HmsMessageService`'den genişleyen bir sınıf oluşturun ve aşağıdaki yöntemleri ekleyin.

  <Warning>
    Zaten `HmsMessageService`'i genişleten bir sınıfınız varsa, başka bir sınıf oluşturmak yerine iki yeni `OneSignalHmsEventBridge` satırını ekleyin.
  </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);
    }
  }
  ```

  Bu, `onNewToken` ve `onMessageReceived`'i `OneSignalHmsEventBridge` aracılığıyla OneSignal'e iletmek içindir.

  Daha önce `HmsMessageService`'i genişleten bir sınıfınız yoksa, bunu `<application>` etiketi altında `AndroidManifest.xml` dosyanıza eklediğinizden emin olun.

  ```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 yapıları için Google kütüphanelerini hariç tutun (isteğe bağlı)

<Accordion title="Daha fazla detay...">
  <Tabs>
    <Tab title="Seçenek 1">
      Uygulamanız yalnızca Huawei AppGallery'de kullanılabilir olacaksa ve OneSignal'in içerdiği Google ile ilgili bağımlılıkları hariç tutmak istiyorsanız, `app/build.gradle` dosyanızda `implementation` ile `exclude` kullanabilirsiniz.

      <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="Seçenek 2">
      Uygulamanız hem Google Play Store hem de Huawei AppGallery için olacaksa ve APK'nızı daha küçük yapmak için hangi kütüphaneleri ekleyeceğiniz konusunda seçici olmak istiyorsanız, buildTypes veya varyantlara göre bağımlılıklar ekleyebilirsiniz. Örnek:

      <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>

### FCM yerine HMS'i tercih edin (isteğe bağlı)

<Accordion title="Daha fazla detay...">
  ***Yukarıda Huawei AppGallery yapısı için [Google Kütüphanelerini hariç tuttuysan](./huawei-sdk-setup#omit-google-libraries-for-huawei-appgallery-builds-optional), bu adım geçerli değildir.***

  Varsayılan olarak OneSignal, her ikisi de uygulamanıza dahil edilmişse FCM'yi HMS'e tercih eder. Bunu HMS'i tercih edecek şekilde değiştirmek isterseniz `AndroidManifest.xml` dosyanıza aşağıdakileri ekleyebilirsiniz:

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

***

## Huawei sorun giderme

Test ederken, [OneSignal setLogLevel yöntemini](./mobile-sdk-reference#setloglevel) VERBOSE olarak ayarlı tuttuğunuzdan emin olun.

Günlükleri kontrol ederek hataları ve [Huawei Common Error Codes](https://developer.huawei.com/consumer/en/doc/development/HMS-2-References/hmssdk_huaweipush_api_reference_errorcode)'u görün.

<Accordion title="6003 hatası">
  OneSignal SDK ile Huawei `pushToken` için kayıt olurken `6003` hatasından kaçınmak için bir debug veya release keystore imzası oluşturmanız gerekebilir (doğru uygulama derleme yolunu seçin, `debug` veya `release`). ["Configure a Signature" bölümüne](https://developer.huawei.com/consumer/en/doc/HMS-Guides/Preparations#h2-1584707362385) bakın
</Accordion>

<Accordion title="notification_types: -25">
  `"notification_types":-25`, OneSignal'in bir push token almak için Huawei'nin HMS'inden yanıt beklerken zaman aşımına uğradığı anlamına gelir. Bu büyük olasılıkla başka bir 3. taraf HMS push SDK'sının veya kendi HmsMessageService'inizin bu olayı OneSignal yerine almasından kaynaklanır.

  Lütfen [bunu nasıl kontrol edeceğiniz ve bu durumda olayı nasıl ileteceğiniz hakkındaki adımı](#compatibility-with-other-hms-push-libraries-or-your-own-hmsmessageservice-class) inceleyin.
</Accordion>

<Accordion title="notification_types: -28">
  Bu, HMS'in push için gereken bir sınıfın uygulamada eksik olduğu anlamına gelir. `build.gradle` dosyasında sadece `com.huawei.hms:push`'a sahip olmak bu özel hatanın artık oluşmamasına neden olacaktır. Ancak, agresif Proguard veya R8 ayarlarınız varsa, bu sorunlara neden olabilir. Sorunun kaynağının bu olup olmadığını görmek için, varsa `minifyEnabled`'ı geçici olarak kapatmanızı öneririz.

  Ayrıca, diğer HMS kütüphanelerinin ana sürüm sürümlerini karıştırmamalısınız. 4 veya 5 ile başlayın. 3'ten 5'e kadar bir karışıma sahip olmadığınızdan emin olun, bu da başka hatalara yol açacaktır
</Accordion>

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

  Proguard veya R8 kurallarınızı kontrol ederek düzgün bir şekilde ayarlandığından emin olun. İlgili olup olmadığını görmek için geçici olarak devre dışı bırakabilirsiniz. Proguard veya R8'i devre dışı bıraktıktan sonra sorunu düzeltirse, bu kılavuzu takip edebilir ve tekrar açabilirsiniz. ["Configure a Signature" bölümüne](https://developer.huawei.com/consumer/en/doc/HMS-Guides/Preparations#h2-1584707362385) bakın

### 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.).
