Can anyone help me with handling back buttons for android?. I a using Android Activity #decompose

, which contains a fragment, then fragment contains the RootComponent. When i am pressing back button on Android, its popping the fragment rather the popping a single component.

class RecceSectionsComponent(
    componentContext: ComponentContext,
    recceId: String,
    sectionId: String,
    sectionTitle: String,
    recceGuide: Guide?,
    projectId: String?,
    storeFactory: StoreFactory,
    private val output: (Output) -> Unit
) : ComponentContext by componentContext {
    private val recceStore = instanceKeeper.getStore {
        RecceDetailsStoreFactory(
            storeFactory = storeFactory
        ).create()
    }

    private val backCallback = BackCallback {
        onOutput(Output.NavigateBack)
    }


    init {
        lifecycle.subscribe(object : Lifecycle.Callbacks {

            override fun onResume() {
                super.onResume()
            }

            override fun onStart() {
                super.onStart()
            }
        })
        backHandler.register(backCallback)
        backCallback.isEnabled = true
    }

    val recceId = recceId

    val sectionId = sectionId

    val sectionTitle = sectionTitle
    val recceGuide = recceGuide

    val projectId = projectId

    @OptIn(ExperimentalCoroutinesApi::class)
    val state: StateFlow<RecceDetailsStore.State> = recceStore.stateFlow

    fun onEvent(event: RecceDetailsStore.Intent) {
        recceStore.accept(event)
    }

    fun onOutput(output: Output) {
        output(output)
    }

    sealed class Output {
        object NavigateBack : Output()
        object Logout : Output()
        data class OpenFullScreenComponent<T>(
            val imagesList: List<T>,
            val initialImageIndex: Int,
            val openFrom: String,
            val elementName: String? = null
        ) : Output()
    }
}

Above is RecceSectionsComponent declared in RootComponent.

private val navigation = StackNavigation<Configuration>()

private val stack = childStack(
    source = navigation,
    initialConfiguration = getInitConfig(),
    childFactory = ::createChild
)

I think you don't need

BackCallback

in your RecceSectionsComponent. Just pass

handleBackButton = true

to

childStack(...)

.
