# Android API移行ガイド（旧→新）

このページは、旧 Android API（`NubrickClient` 系）から現行 API（`NubrickSDK` 系）への移行ポイントをまとめたものです。

## 対応表

| 旧API                                    | 新API                                           |
| --------------------------------------- | ---------------------------------------------- |
| `NubrickClient(config, context)`        | `NubrickSDK.initialize(context, config)`       |
| `nubrick.experiment.dispatch(...)`      | `NubrickSDK.dispatch(...)`                     |
| `nubrick.experiment.Embedding(...)`     | `NubrickSDK.Embedding(...)`                    |
| `nubrick.experiment.RemoteConfig(...)`  | `NubrickSDK.RemoteConfig(...)`                 |
| `nubrick.experiment.remoteConfig(...)`  | `NubrickSDK.remoteConfig(...)`                 |
| `nubrick.user.setProperties(...)`       | `NubrickSDK.setUserProperties(...)`            |
| `nubrick.user.setProperty(...)`         | `NubrickSDK.setUserProperty(...)`              |
| `nubrick.user.getProperty(...)`         | `NubrickSDK.getUserProperty(...)`              |
| `nubrick.user.userId / getProperties()` | `NubrickSDK.getUserId() / getUserProperties()` |
| `NubrickProvider(client = ...)`         | `NubrickProvider { ... }`                      |
| `nubrick.close()`                       | （不要）                                           |

## 主要な書き換え例

### 1) 初期化

```kotlin
// Before
val nubrick = NubrickClient(
    config = Config(projectId = "<PROJECT_ID>"),
    context = applicationContext,
)

// After
NubrickSDK.initialize(
    context = applicationContext,
    config = Config(projectId = "<PROJECT_ID>"),
)
```

### 2) 埋め込み（Compose）

```kotlin
// Before
nubrick.experiment.Embedding("TOP_COMPONENT")

// After
NubrickSDK.Embedding("TOP_COMPONENT")
```

### 3) ユーザープロパティ

```kotlin
// Before
nubrick.user.setProperties(mapOf("plan" to "gold"))

// After
NubrickSDK.setUserProperties(mapOf("plan" to "gold"))
```

### 4) Provider

```kotlin
// Before
NubrickProvider(client = nubrick) {
    AppContent()
}

// After
NubrickProvider {
    AppContent()
}
```

## 注意点

* 旧 `NubrickClient` / `NubrickExperiment` を前提としたコードはそのままでは動きません。
* `NubrickSDK.initialize(...)` は、他の API を呼ぶ前に 1 回だけ実行してください。
* Compose でオーバーレイ配信を表示する場合は、`NubrickProvider` でルートを包んでください。
