fix: store images as files instead of Base64 in SQLite to avoid CursorWindow crash
Save image data to filesDir/chat_images/ and persist only file paths in DB, preventing SQLiteBlobTooBigException when images exceed 2MB CursorWindow limit. Also includes: - Camera/gallery image attachment implementation - Gradle 9.3.1 / AGP 9 / compileSdk 36 upgrade - Release signing configuration - Minor bug fixes (MessageInput alignment, MessageList ordering) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# PicoClaw Android APK - チャットUI設計プラン
|
||||
|
||||
## Context
|
||||
|
||||
PicoClawはTermux上で動作するGo製AIエージェント。WebSocketサーバーチャネル(`pkg/channels/websocket.go`)を通じて外部クライアントと通信可能。このWSサーバーに接続するAndroid APKを作成する。初期リリースはテキスト+画像チャットUI、将来的にボイスUI（Googleアシスタント風）を追加予定。
|
||||
|
||||
## WSプロトコル（確認済み）
|
||||
|
||||
```
|
||||
Endpoint: ws://127.0.0.1:18793/ws
|
||||
|
||||
Client → Server: {"content":"text", "sender_id":"optional", "images":["raw_base64_no_prefix"]}
|
||||
Server → Client: {"content":"text"}
|
||||
```
|
||||
|
||||
- imagesはraw base64（`data:`プレフィックスなし）。サーバー側で`data:image/png;base64,`を付与（websocket.go:237）
|
||||
- sender_id未指定時、サーバーがUUIDを割り当て（websocket.go:227-230）
|
||||
|
||||

|
||||
|
||||

|
||||
| Gradle | **9.1+** | AGP 9.0要件 |
|
||||

|
||||
|
||||
## アーキテクチャ — マルチモジュール構成
|
||||
|
||||
**Jetpack Compose + MVVM + Clean Architecture + Feature Module分離**
|
||||
|
||||
```
|
||||
:app → アプリのエントリーポイント、DI、ナビゲーション
|
||||
:feature:chat → チャットUI（Compose画面、ViewModel、UIコンポーネント）
|
||||
:core:domain → ドメインモデル、リポジトリinterface、UseCases
|
||||
:core:data → リポジトリ実装、Room DB、WebSocketClient、DTO
|
||||
:core:ui → 共有テーマ、共有コンポーネント
|
||||
```
|
||||
|
||||
**依存関係**:
|
||||
```
|
||||
:app → :feature:chat, :core:domain, :core:data, :core:ui
|
||||
:feature:chat → :core:domain, :core:ui
|
||||
:core:data → :core:domain
|
||||
:core:ui → (compose dependencies only)
|
||||
```
|
||||
|
||||
**利点**: ボイスUI追加時は `:feature:voice` を新設するだけ。`:core:domain`と`:core:data`はそのまま共有。

|

|
||||
## 各層の設計
|
||||
|
||||
### :core:data — Data層
|
||||
|
||||
#### Room DB（メッセージ永続化）
|
||||
|
||||
**MessageEntity**:
|
||||
```kotlin
|
||||
@Entity(tableName = "messages")
|
||||
data class MessageEntity(
|
||||
@PrimaryKey val id: String, // UUID
|
||||
val content: String,
|
||||
val sender: String, // "USER" or "AGENT"
|
||||
val imageBase64List: String?, // JSON文字列 ["base64_1","base64_2"]
|
||||
val timestamp: Long, // epoch millis
|
||||
val status: String // "SENDING","SENT","FAILED","RECEIVED"
|
||||
)
|
||||
```
|
||||
|
||||
**MessageDao**:
|
||||
```kotlin
|
||||
@Dao
|
||||
interface MessageDao {
|
||||
@Query("SELECT * FROM messages ORDER BY timestamp DESC LIMIT :limit")
|
||||
fun getRecentMessages(limit: Int): Flow<List<MessageEntity>>
|
||||
|
||||
@Query("SELECT * FROM messages WHERE timestamp < :beforeTimestamp ORDER BY timestamp DESC LIMIT :limit")
|
||||
suspend fun getMessagesBefore(beforeTimestamp: Long, limit: Int): List<MessageEntity>
|
||||
|
||||
@Insert(onConflict = OnConflictStrategy.REPLACE)
|
||||
suspend fun insert(message: MessageEntity)
|
||||
|
||||
@Update
|
||||
suspend fun update(message: MessageEntity)
|
||||
}
|
||||
```
|
||||
|
||||
**AppDatabase**:
|
||||
```kotlin
|
||||
@Database(entities = [MessageEntity::class], version = 1)
|
||||
@TypeConverters(Converters::class)
|
||||
abstract class AppDatabase : RoomDatabase() {
|
||||
abstract fun messageDao(): MessageDao
|
||||
}
|
||||
```
|
||||
|
||||
#### ページネーション戦略
|
||||
|
||||
```
|
||||
起動時:
|
||||
→ DAO.getRecentMessages(limit=50) をFlowでobserve
|
||||
→ 最新50件が表示される → 新メッセージはinsert → Flowが自動更新
|
||||
|
||||
スクロール遡り:
|
||||
→ LazyColumnの先頭付近に到達を検知
|
||||
→ Repository.loadMore() → _displayLimitを+30
|
||||
→ RoomのFlowが自動的に再クエリ → UIに反映
|
||||
```
|
||||
|
||||
#### WebSocketClient — Ktor Client (OkHttpエンジン) ベース
|
||||
- `connectionState: StateFlow<ConnectionState>` で接続状態を公開
|
||||
- `incomingMessages: SharedFlow<WsOutgoing>` でサーバー応答を公開
|
||||
- `connect()` / `disconnect()` / `send(dto)` メソッド
|
||||
- exponential backoff自動再接続（1s→2s→4s→8s→max 30s）
|
||||
|
||||
```kotlin
|
||||
val client = HttpClient(OkHttp) {
|
||||
install(WebSockets)
|
||||
engine {
|
||||
preconfigured = OkHttpClient.Builder()
|
||||
.pingInterval(30, TimeUnit.SECONDS)
|
||||
.build()
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### ChatRepositoryImpl — Room + WS統合
|
||||
|
||||
```kotlin
|
||||
class ChatRepositoryImpl(
|
||||
private val webSocketClient: WebSocketClient,
|
||||
private val messageDao: MessageDao,
|
||||
private val scope: CoroutineScope
|
||||
) : ChatRepository {
|
||||
|
||||
private val _displayLimit = MutableStateFlow(INITIAL_LOAD_COUNT) // 50
|
||||
|
||||
override val messages: StateFlow<List<ChatMessage>> =
|
||||
_displayLimit.flatMapLatest { limit ->
|
||||
messageDao.getRecentMessages(limit)
|
||||
}.map { entities ->
|
||||
entities.map { MessageMapper.toDomain(it) }.reversed()
|
||||
}.stateIn(scope, SharingStarted.Lazily, emptyList())
|
||||
|
||||
override val connectionState = webSocketClient.connectionState
|
||||
|
||||
init {
|
||||
scope.launch {
|
||||
webSocketClient.incomingMessages.collect { dto ->
|
||||
val entity = MessageMapper.toEntity(dto)
|
||||
messageDao.insert(entity)
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
override suspend fun sendMessage(text: String, images: List<ImageAttachment>) {
|
||||
val entity = MessageMapper.toEntity(text, images, MessageStatus.SENDING)
|
||||
messageDao.insert(entity)
|
||||
val wsDto = MessageMapper.toWsIncoming(text, images)
|
||||
val success = webSocketClient.send(wsDto)
|
||||
messageDao.update(entity.copy(status = if (success) "SENT" else "FAILED"))
|
||||
}
|
||||
|
||||
override fun loadMore() {
|
||||
_displayLimit.update { it + PAGE_SIZE }
|
||||
}
|
||||
|
||||
companion object {
|
||||
const val INITIAL_LOAD_COUNT = 50
|
||||
const val PAGE_SIZE = 30
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### DTO — `@Serializable`
|
||||
|
||||
```kotlin
|
||||
@Serializable
|
||||
data class WsIncoming(
|
||||
val content: String,
|
||||
@SerialName("sender_id") val senderId: String? = null,
|
||||
val images: List<String>? = null
|
||||
)
|
||||
|
||||
@Serializable
|
||||
data class WsOutgoing(val content: String)
|
||||
```
|
||||
|
||||
### :core:domain — Domain層
|
||||
|
||||
**ChatMessage** — `id, content, sender(USER/AGENT), images: List<String>, timestamp, status`
|
||||
|
||||
**ConnectionState** — `DISCONNECTED, CONNECTING, CONNECTED, RECONNECTING`
|
||||
|
||||
**ImageAttachment** — `uri, base64, mimeType`
|
||||
|
||||
**ChatRepository interface**:
|
||||
```kotlin
|
||||
interface ChatRepository {
|
||||
val messages: StateFlow<List<ChatMessage>>
|
||||
val connectionState: StateFlow<ConnectionState>
|
||||
suspend fun sendMessage(text: String, images: List<ImageAttachment> = emptyList())
|
||||
fun loadMore()
|
||||
fun connect()
|
||||
fun disconnect()
|
||||
}
|
||||
```
|
||||
|
||||
**UseCases** — `SendMessageUseCase`, `ObserveMessagesUseCase`, `ObserveConnectionUseCase`, `LoadMoreMessagesUseCase`
|
||||
|
||||
### :core:ui — 共有UI
|
||||
|
||||
テーマ定義（Color, Type, Theme）。将来的に共有コンポーネントもここに配置。
|
||||
|
||||
### :feature:chat — チャットUI
|
||||
|
||||
**ChatUiState**:
|
||||
```kotlin
|
||||
data class ChatUiState(
|
||||
val messages: List<ChatMessage> = emptyList(),
|
||||
val connectionState: ConnectionState = ConnectionState.DISCONNECTED,
|
||||
val inputText: String = "",
|
||||
val pendingImages: List<ImageAttachment> = emptyList(),
|
||||
val isLoadingMore: Boolean = false,
|
||||
val canLoadMore: Boolean = true,
|
||||
val error: String? = null
|
||||
)
|
||||
```
|
||||
|
||||
**ChatViewModel** — Koin `koinViewModel()`で注入
|
||||
|
||||
**Compose UI階層**:
|
||||
```
|
||||
ChatScreen
|
||||
├── ConnectionBanner # 接続状態（赤/黄/非表示）
|
||||
├── MessageList (weight 1f) # LazyColumn (reverseLayout=true)
|
||||
│ ├── Loading indicator # isLoadingMore時
|
||||
│ └── MessageBubble # 右=ユーザー、左=エージェント
|
||||
└── Bottom Column
|
||||
├── ImagePreviewRow # 送信前サムネイル
|
||||
└── MessageInput # [カメラ][ギャラリー][TextField][送信]
|
||||
```
|
||||
|
||||
**スクロール検知でloadMore**:
|
||||
```kotlin
|
||||
val listState = rememberLazyListState()
|
||||
val shouldLoadMore by remember {
|
||||
derivedStateOf {
|
||||
val lastVisibleItem = listState.layoutInfo.visibleItemsInfo.lastOrNull()
|
||||
lastVisibleItem != null &&
|
||||
lastVisibleItem.index >= listState.layoutInfo.totalItemsCount - 5
|
||||
}
|
||||
}
|
||||
LaunchedEffect(shouldLoadMore) {
|
||||
if (shouldLoadMore) viewModel.onLoadMore()
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||

|
||||
|
||||
```kotlin
|
||||
// app/di/AppModule.kt
|
||||
val appModule = module {
|
||||

|
||||
single {
|
||||
Room.databaseBuilder(androidContext(), AppDatabase::class.java, "picoclaw.db").build()
|

.pingInterval(30, TimeUnit.SECONDS)
|
||||
.build()
|

}
|

// WebSocketClient
|

|
||||
|

### 各モジュールのbuild.gradle.kts概要
|
||||
|
||||
**:app** — `android-application`, `serialization` → depends on all modules
|
||||
**:feature:chat** — `android-library` → depends on `:core:domain`, `:core:ui`
|
||||
**:core:domain** — `android-library` → depends on nothing (pure Kotlin + coroutines)
|
||||
**:core:data** — `android-library`, `serialization`, `ksp` → depends on `:core:domain` (Room, Ktor, DTO)
|
||||
**:core:ui** — `android-library` → depends on nothing (Compose theme only)
|
||||
|
||||
KSPは`:core:data`モジュールのみで使用（Room compiler）。

|
||||
|
||||
## 注意点
|
||||
|
||||
- **Cleartext通信**: `ws://127.0.0.1`への通信に`network_security_config.xml`でlocalhost/127.0.0.1のみ許可
|
||||
- **画像base64**: サーバーが`data:image/png;base64,`を自動付与するため、クライアントはraw base64のみ送信
|
||||
- **画像のDB保存**: 画像base64はMessageEntityにJSON配列文字列として保存。TypeConverterで変換
|
||||
- **Ktor WS ping**: OkHttpエンジン使用時はOkHttpBuilder側の`pingInterval`で設定
|
||||
- **AGP 9.0**: `kotlin-android`プラグイン不適用、`kotlin.compilerOptions`を使用
|
||||
- **マルチモジュール**: 各library moduleは`android.namespace`を個別設定
|

||||
## 実装順序
|
||||
|
||||
### Phase 1: プロジェクトスキャフォールド + マルチモジュール
|
||||
1. `android/` ディレクトリ構造（5モジュール分）
|
||||
2. ルート `build.gradle.kts`、`settings.gradle.kts`（全module include）、`libs.versions.toml`
|
||||
3. `gradle.properties`
|
||||
4. 各モジュールの `build.gradle.kts`
|
||||
5. `app/` の `AndroidManifest.xml` + `network_security_config.xml` + リソース
|
||||
6. Gradleラッパー生成
|
||||
|
||||
### Phase 2: :core:domain
|
||||
7. `ConnectionState.kt`、`ChatMessage.kt`、`ImageAttachment.kt`
|
||||
8. `ChatRepository.kt` (interface)
|
||||
9. 4つのUseCase
|
||||
|
||||
### Phase 3: :core:ui
|
||||
10. Theme（Color.kt, Type.kt, Theme.kt）
|
||||
|
||||
### Phase 4: :core:data — Room
|
||||
11. `MessageEntity.kt` + `Converters.kt`
|
||||
12. `MessageDao.kt`
|
||||
13. `AppDatabase.kt`
|
||||
|
||||
### Phase 5: :core:data — WebSocket + Repository
|
||||
14. `WsIncoming.kt`、`WsOutgoing.kt` (@Serializable)
|
||||
15. `MessageMapper.kt`
|
||||
16. `WebSocketClient.kt`（Ktor + auto-reconnect）
|
||||
17. `ChatRepositoryImpl.kt`（Room + WS統合、ページネーション）
|
||||
|
||||
### Phase 6: :feature:chat
|
||||
18. `ChatUiState.kt`、`ChatEvent.kt`
|
||||
19. `ChatViewModel.kt`（loadMore対応）
|
||||
20. UIコンポーネント（ConnectionBanner, MessageBubble, MessageList, ImagePreview, MessageInput）
|
||||
21. `ChatScreen.kt`（スクロール検知+ページネーション）
|
||||
|
||||
### Phase 7: :app
|
||||
22. `AppModule.kt`（Koin全体module）
|
||||
23. `PicoClawApp.kt`
|
||||
24. `MainActivity.kt`
|
||||

|
||||
|
||||
## 検証方法
|
||||
|
||||
1. Termuxでpicoclaw起動（WSサーバーが`127.0.0.1:18793`でリスン）
|
||||
2. APKをビルド・インストール（`./gradlew assembleDebug`）
|
||||
3. アプリ起動 → ConnectionBannerが「Connected」表示を確認
|
||||
4. テキスト送信 → エージェントからの応答がチャットに表示されることを確認
|
||||
5. アプリを再起動 → 前回のチャット履歴がRoomから読み込まれて表示されることを確認
|
||||
6. 50件以上メッセージを蓄積 → 上にスクロール → 古いメッセージが動的にロードされることを確認
|
||||
7. カメラ/ギャラリーから画像添付+テキスト送信 → エージェントが画像を認識した応答を返すことを確認
|
||||
8. WSサーバーを停止 → 「Reconnecting」表示 → サーバー再起動後に自動再接続を確認
|
||||

|
||||
|
||||
## 将来の拡張
|
||||
|
||||
- **:feature:voice**: `:core:domain`と`:core:data`をそのまま共有。SpeechRecognizer+TextToSpeechのUI層のみ新設
|
||||
- **複数サーバー**: `WebSocketClient`のurl引数を動的に
|
||||
- **メッセージ検索**: Room DAOにFTS4クエリ追加
