Фактические/ожидаемые забавы в совместном броске noSuchMethod в мультиплатформенной системе Kotlin

#android #kotlin #android-jetpack-compose #kotlin-multiplatform #compose-desktop

Вопрос:

Я разрабатываю фиктивное приложение для погоды с помощью мультиплатформенной платформы Kotlin. Я использую Decompose и MVIKotlin, чтобы попытаться поделиться всей бизнес-логикой, кроме собственных пользовательских интерфейсов, SwiftUI для IOS и Compose для настольных компьютеров и Android.

Я пытаюсь создать ожидаемую композицию (для темной темы и для загрузки изображений).

 // In common main
@Composable
expect fun isDarkMode() : Boolean

@Composable
expect fun loadWeatherIcon(id : Int) : Painter


// In android main 
@Composable
actual fun isDarkMode() : Boolean {
    return androidx.compose.foundation.isSystemInDarkTheme()
}

@Composable
actual fun loadWeatherIcon(id : Int) : Painter {
    return painterResource(id)
}

//In Desktop main
@Composable
actual fun isDarkMode() : Boolean {
    return false //isSystemInDarkTheme()
}
@Composable
actual fun loadWeatherIcon(id : Int) : Painter {
    return loadWeatherIcon(id)
}

Это означает, что все они реализованы и есть, но по какой-то причине сбой происходит с ошибкой noSuchMethod. Я обнаружил некоторые похожие проблемы, но все они имели функции приостановки и параметры по умолчанию. Между тем мой подход должен работать, как в примере jetpack todo compose, вот мой проект (если вы хотите проверить, что происходит, вы можете просто клонировать его и запустить, он должен немедленно рухнуть).

Ответ №1:

Я столкнулся с аналогичной проблемой, когда @Composable аннотированная ожидаемая функция не была видна во время выполнения в другом модуле Gradle. Отсюда java.lang.NoSuchMethodError и исключение. Решение состояло в том, чтобы сделать ожидаемую функцию внутренней и делегировать этой внутренней функции общедоступную функцию-оболочку.

Сбои:

 @Composable
expect fun Image() { ... }

Не разбивается:

 @Composable
internal expect fun InternalImage() { ... }

@Composable
fun Image() {
    InternalImage()
}
