这里 SDK mapLoader.getMapPackageAtCoordinate 返回 true 但我从来没有得到回调结果答案

【问题标题】：Here SDK mapLoader.getMapPackageAtCoordinate return true but I never get result on callback这里 SDK mapLoader.getMapPackageAtCoordinate 返回 true 但我从来没有得到回调结果

【问题描述】：

我正在使用 Here SDK，初始化后一切正常，但是当我调用时：

val getMapPackageResult = mapLoader.getMapPackageAtCoordinate(GeoCoordinate(52.500556, 13.398889, 0.0))

要安装地图包，MapPackageAtCoordinateListener 回调永远不会被调用！

当我在没有 GeoCoordination 的情况下拨打 mapLoader.getMapPackages 时，情况就不一样了！

后端对我的试用帐户有任何限制吗？有什么建议吗？

val diskCacheRoot = "${Environment.getExternalStorageDirectory().path}${File.separator}.isolated-here-maps"

MapSettings.setIsolatedDiskCacheRootPath(diskCacheRoot, HERE_MAP_ACTION)


mapLoader = MapLoader.getInstance()

mapLoader.addListener(object : MapLoader.Listener {

    override fun onProgress(i: Int) {
        Timber.i("onProgress $i")
    }

    override fun onInstallationSize(l: Long, l1: Long) {
        Timber.i("onInstallationSize")
    }

    override fun onGetMapPackagesComplete(mapPackage: MapPackage, resultCode: MapLoader.ResultCode) {
        Timber.i("onGetMapPackagesComplete name = " + mapPackage.englishTitle + " , resultCode = " + resultCode)
    }

    override fun onCheckForUpdateComplete(b: Boolean, s: String, s1: String, resultCode: MapLoader.ResultCode) {
        Timber.i("onCheckForUpdateComplete")
    }

    override fun onPerformMapDataUpdateComplete(mapPackage: MapPackage, resultCode: MapLoader.ResultCode) {
        Timber.i("onPerformMapDataUpdateComplete")
    }

    override fun onInstallMapPackagesComplete(mapPackage: MapPackage, resultCode: MapLoader.ResultCode) {
        Timber.i("onInstallMapPackagesComplete resultCode = $resultCode")
        if (resultCode == MapLoader.ResultCode.OPERATION_SUCCESSFUL) {
            Timber.i("onInstallMapPackagesComplete mapPackage = " + mapPackage.title)
        } else {
            listener.onError(NavigationException())
        }
    }

    override fun onUninstallMapPackagesComplete(mapPackage: MapPackage, resultCode: MapLoader.ResultCode) {
        Timber.i("onUninstallMapPackagesComplete")
    }
})

mapLoader.addMapPackageAtCoordinateListener({ mapPackage, geoCoordinate, resultCode ->
    Timber.i("onGetMapPackageAtCoordinateComplete name = ${mapPackage?.englishTitle}, resultCode = $resultCode")
    val packages = ArrayList<Int>()
    mapPackage?.let {
        packages.add(it.id)
        mapLoader.installMapPackages(packages)
    } ?: Timber.e("No package loaded")
})

【解决方案1】：

答案是，不是Here SDK！

另一个原生库由于某种原因出现Signal = SIGUSR2 (signal SIGUSR2) 错误，因此，整个 Here SDK 停止工作！

无法跟踪问题的原因是 Java 包装器工作正常，但其代码的 C 部分不再工作。
