OfflineMapAreas

Take a web map offline by downloading map areas.

Features

Supports both ahead-of-time (preplanned) and on-demand map areas for an offline enabled web map. This OfflineMapAreas composable:

• Displays a list of map areas.

• Shows download progress and status for map areas.

• Opens a map area for viewing when selected.

• Provides options to view details about downloaded map areas.

• Supports removing downloaded offline map areas files from the device.

For preplanned workflows, this composable:

• Displays a list of available preplanned map areas from an offline-enabled web map that contains preplanned map areas when the network is connected.

• Downloads preplanned map areas in the list.

• Displays a list of downloaded preplanned map areas on the device when the network is disconnected.

For on-demand workflows, this composable:

• Allows users to add and download on-demand map areas to the device by specifying an area of interest and level of detail.

• Displays a list of on-demand map areas available on the device that are tied to a specific web map.

Workflow example:

val selectedMap = mutableStateOf<ArcGISMap?>(null)

val displayedMap get() = selectedMap.value ?: onlineMap

val offlineMapState = OfflineMapState(
    arcGISMap = displayedMap,
    onSelectionChanged = { offlineMap ->
        selectedMap.value = offlineMap
    }
)

@Composable
fun SheetContent() {
    OfflineMapAreas(
        offlineMapState = offlineMapState,
        modifier = Modifier
            .padding(horizontal = 16.dp)
            .animateContentSize()
    )
}
