# Custom HMS Implementation

If you have custom Huawei Messaging integration, please see usage below.

#### Android Implementation

Add the following line to your `AndroidManifest.xml` file inside the `application` tag to remove Netmera's default HMS service:

```xml
<service
   android:name="com.netmera.nmhms.NMHuaweiService"
   tools:node="remove" />
```

#### React Native Implementation

Update `HuaweiPushKit` methods like below:

```typescript
HmsPushInstanceId.getToken("")
   .then((result) => {
       Netmera.onNetmeraNewToken(result.result)
   })

HmsPushEvent.onRemoteMessageReceived((event) => {
  const remoteMessage = new RNRemoteMessage(event.msg);
  let data = JSON.parse(remoteMessage.getData());
  if (Netmera.isNetmeraRemoteMessage(data)) {
    Netmera.onNetmeraHuaweiPushMessageReceived(
      remoteMessage.getFrom(),
      data,
    );
  }
});

HmsPushMessaging.setBackgroundMessageHandler(async dataMessage => {
  const remoteMessage = new RNRemoteMessage(dataMessage);
  let data = JSON.parse(remoteMessage.getData());
  if (Netmera.isNetmeraRemoteMessage(data)) {
    Netmera.onNetmeraHuaweiPushMessageReceived(
        remoteMessage.getFrom(),
        data,
    );
  }
});
```
