RetryAndFollowUpInterceptor - java.io.IOException: Canceled

从 buildDirectionsApiClient 和报告中所示的 enqueueCall 回调开始，然后跟踪 Mapbox Directions SDK 如何使用 Retrofit 和 OkHttp 处理取消。重现间歇性出现的 IOException: Canceled 情况，并确定该调用是被客户端生命周期取消的，还是被并发请求取消的。确定取消原因，并通过可复现的案例或已确认的 SDK 缺陷进行记录，即视为完成。

Issue

Multiple RetryAndFollowUpInterceptor - java.io.IOException: Canceled

Description

We are getting randomly multiple java.io.IOException: Canceled when using the Mapbox Directions SDK. Code snippet is:

SDK used

//Mapbox Directions API
implementation "com.mapbox.mapboxsdk:mapbox-sdk-services:6.13.0"

Code Snippet

for origin = "Point{type=Point, bbox=null, coordinates=[-58.449951171875, -34.55467987060547]}"
for destination = Point{type=Point, bbox=null, coordinates=[-58.484619140625, -34.57625961303711]}

private fun buildDirectionsApiClient(origin: Point, destination: Point): MapboxDirections {
    val routeOptions = RouteOptions.builder()
        .geometries(DirectionsCriteria.GEOMETRY_POLYLINE6)
        .overview(DirectionsCriteria.OVERVIEW_SIMPLIFIED)
        .profile(DirectionsCriteria.PROFILE_DRIVING)
        .coordinatesList(listOf(origin, destination))
        .build()

    return MapboxDirections.builder()
        .accessToken(accessToken)
        .routeOptions(routeOptions)
        .build()
}

and the way we are executing the calls is:

client?.enqueueCall(object : Callback<DirectionsResponse> {
            override fun onResponse(
                call: Call<DirectionsResponse>,
                response: Response<DirectionsResponse>
            ) {
                response.body()?.routes()?.firstOrNull()?.let { route ->

                    mapbox.getStyle {
                        val source: GeoJsonSource? = it.getSourceAs(ROUTE_SOURCE_ID)
                        val lineString = LineString.fromPolyline(
                            route.geometry()!!,
                            Constants.PRECISION_6
                        )
                        // Set the map's camera position taking into account the route drawing
                        val coordinateList = lineString.coordinates()
                        animateMarker.setBoundary(coordinateList)

                        val camera = mapbox.cameraForCoordinates(coordinateList, getPadding())
                        mapbox.easeTo(camera, source, lineString)
                    }
                }
            }

            override fun onFailure(call: Call<DirectionsResponse>, t: Throwable) {
                DevMetrics.monitor(errorParams("Mapbox cannot draw route points reason is ${t.cause} - ${t.message}"))
                onError()
            }
        })

Not sure if we are doing something wrong because it mostly works and draw the route but randomly it shows us this exception coming from Retrofit and OkHttp
