 Instanz -Erstellungsfehler: Es konnte keine Instanz für 'AppDatabase erstellen. Implementierung für AppDatabase nicht fi

Post by Anonymous »

Ich habe ein Problem im Zusammenhang mit der Verwendung von Koin di zusammen mit Raum DB.
Ich habe alle benötigten Komponenten für Raum erstellt wie folgt:

Code: Select all

@Dao
interface CharacterDAO {
@Query("SELECT * FROM character")
suspend fun getAll(): List

@Query("SELECT * FROM character WHERE uid IN (:characterIds)")
suspend fun loadAllByIds(characterIds: IntArray): List

@Query("SELECT * FROM character WHERE name LIKE :first")
suspend fun findByName(first: String): CharacterEntity

@Insert(onConflict = OnConflictStrategy.REPLACE)
suspend fun insertAll(vararg characters: List)

suspend fun insert(character: CharacterEntity): Boolean

@Delete
suspend fun delete(character: CharacterEntity)

@Query("DELETE FROM character")
suspend fun clearTable()
}

@Database(entities = [CharacterEntity::class], version = 1, exportSchema = false) // entities = [Character::class]
abstract class AppDatabase : RoomDatabase() {
abstract fun characterDao(): CharacterDAO
}

@Entity(tableName = "character")
data class CharacterEntity(
@PrimaryKey val id: String,
val name: String,
val actor: String,
val alive: Boolean,
val ancestry: String,
val dateOfBirth: String,
val eyeColour: String,
val gender: String,
val hairColour: String,
val hogwartsStaff: Boolean,
val hogwartsStudent: Boolean,
val house: String,
val image: String,
val patronus: String,
val species: String,
val wizard: Boolean,
val yearOfBirth: Int
)
< /code>
Importierte die folgenden Abhängigkeiten in der App Gradle -Datei: < /p>
// Room
implementation "androidx.room:room-runtime:2.5.1"
implementation 'androidx.room:room-ktx:2.5.1'
kapt 'android.arch.persistence.room:compiler:1.1.1'

// Koin for Android
implementation 'io.insert-koin:koin-android:3.4.0'
< /code>
und definierte die folgenden Koin -Module: < /p>
val appModule = module {

single {
WizardsSharedPreferences(get())
}

single {
WizardRepositoryImpl(wizardNetwork = get(), wizardCache = get(), sharedPreferences = get())
}

viewModel { HomeViewModel(wizardRepository = get()) }
viewModel { DetailViewModel(wizardRepository = get()) }

}

val networkingKoinModule = module {

single {
Room.databaseBuilder(
androidApplication(),
AppDatabase::class.java,
"wizards"
).build()
}

single {
val database = get()
database.characterDao()
}

single {
WizardNetworkDataApiImpl()
}

single {
WizardCacheDataApiImpl(get())
}
}
< /code>
Synchronisation und Kompilierung geht gut. Zur Laufzeit in logcat erhalte ich den folgenden Fehler: < /p>

Ich habe bereits versucht, einige Abhängigkeiten hinzuzufügen/zu entfernen, Cache zu ungültig und neu starten und reinigen.companion object {
@Volatile
private var INSTANCE: AppDatabase? = null

fun getInstance(context: Context): AppDatabase {
synchronized(this) {
var instance = INSTANCE
if (instance == null) {
instance = Room
.databaseBuilder(
context.applicationContext,
AppDatabase::class.java,
"wizards"
).fallbackToDestructiveMigration()
.build()
INSTANCE = instance
}
return instance
}

}

}
< /code>
Aber ich erhalte diesen Fehler trotzdem.
Was mache ich falsch? < /p>
