      • estimateTileCacheSize

        public EstimateTileCacheSizeJob estimateTileCacheSize​(ExportTileCacheParameters exportTileCacheParameters)
        Returns a new EstimateTileCacheSizeJob.

        Note - you need to call Job.start() to start the job.

        Parameters:
        exportTileCacheParameters - export tile cache parameters to be used in estimating
        Returns:
        an EstimateTileCacheSizeJob representing the async operation of estimating a tile cache size, the result will be an EstimateTileCacheSizeResult object if completed successfully
        Throws:
        IllegalArgumentException - if exportTileCacheParameters is null
        Since:
        100.4.0
      • exportTileCacheAsync

        @Deprecated
        public ExportTileCacheJob exportTileCacheAsync​(ExportTileCacheParameters exportTileCacheParameters,
                                                       String fileNameWithPath)
        Deprecated.
        Returns a new ExportTileCacheJob.

        Note - you need to call Job.start() to start the job.

        Parameters:
        exportTileCacheParameters - export tile cache parameters to be used in exporting
        fileNameWithPath - a file path, including filename, specifying the destination of the tpk when downloaded to the device. The file name must have a file extension of ".tpk", for example "/data/streets.tpk".
        Returns:
        an ExportTileCacheJob representing the async operation of exporting a tile cache, the result will be a TileCache object if completed successfully
        Throws:
        IllegalArgumentException - if exportTileCacheParameters is null
        IllegalArgumentException - if fileNameWithPath is null or doesn't end in ".tpk"

      • exportTileCache

        public ExportTileCacheJob exportTileCache​(ExportTileCacheParameters exportTileCacheParameters,
                                                  String fileNameWithPath)
        Return a new export tile cache job.

        The resulting job will export tiles from the service, which is referenced by the getUri() property (or its export-enabled alternative), to a local tile cache at the fileNameWithPath. The format of the tile cache is determined by the file extension supplied in the fileNameWithPath parameter.

        • If the download file path ends with ".tpk", the tile cache will use the legacy compact format.
        • If the download file path ends with ".tpkx", the tile cache will use the current compact version 2 format.
        The job will fail if the service does not support exporting tiles, and if a .tpkx format was requested but the format is not supported by the service. The precise reason for failure is reported by ArcGISRuntimeException.getErrorCode().
        Parameters:
        exportTileCacheParameters - export tile cache parameters to be used in exporting
        fileNameWithPath - downloaded tile cache file path that ends with .tpk or .tpkx, depending on the desired format.
        Throws:
        IllegalArgumentException - if exportTileCacheParameters is null
        IllegalArgumentException - if fileNameWithPath is null

      • createDefaultExportTileCacheParametersAsync

        public ListenableFuture<ExportTileCacheParameters> createDefaultExportTileCacheParametersAsync​(Geometry areaOfInterest,
                                                                                                       double minScale,
                                                                                                       double maxScale)
        Creates a default set of export tile cache parameters asynchronously.

        The supported geometry types for the area of interest are Envelope and Polygon. The area of interest must have a spatial reference.

        Where a Polygon is supplied, features and tiles will be filtered according to the polygon geometry, which can help reduce the size of the resulting offline map. Note that the filtered set of tiles may vary, depending on the underlying service.

        Parameters:
        areaOfInterest - the geometry specifying the area to be exported, must be an Envelope or a Polygon
        minScale - the map scale '1:minScale' above which LODs should be exported, can be 0 in which case this parameter is ignored
        maxScale - the map scale '1:maxScale' below which LODs should be exported, can be 0 in which case this parameter is ignored
        Returns:
        a ListenableFuture containing the ExportTileCacheParameters object being created asynchronously
        Throws:
        IllegalArgumentException - if areaOfInterest is null or anything other than an Envelope or a Polygon

      • getApiKey

        public String getApiKey()
        Description copied from interface: ApiKeyResource
        Gets the API key to access API key enabled services and resources in ArcGIS Online.

        An API key is a unique key used to authorize access to specific services and resources in ArcGIS Online. It is also used to monitor access to those services. An API key is created and managed in the ArcGIS developer dashboard and is tied to a specific ArcGIS account. Setting the API key on a specific ApiKeyResource overrides the default key set on ArcGISRuntimeEnvironment.getApiKey().

        Specified by:
        getApiKey in interface ApiKeyResource
        Returns:
        the API key to access API key enabled services and resources in ArcGIS Online

      • getLoadStatus

        public LoadStatus getLoadStatus()
        Description copied from interface: Loadable
        Returns the LoadStatus of the loadable resource.
        Specified by:
        getLoadStatus in interface Loadable
        Returns:
        the LoadStatus of the loadable resource
      • cancelLoad

        public void cancelLoad()
        Description copied from interface: Loadable
        Cancels loading metadata for the object.

        Cancels loading the metadata if the object is loading, and always invokes the done loading listener.

        A load operation that is in progress (LoadStatus.LOADING state) can be cancelled by calling this method and the resource will transition from LoadStatus.LOADING to LoadStatus.FAILED_TO_LOAD state. If the load operation was successfully cancelled, a CancellationException will be returned from Loadable.getLoadError().

        Cancellation should be used carefully because all enqueued done loading listeners for that resource instance will get invoked with an error stating that the operation was cancelled. Thus, one component in the application can cancel the load operation initiated by other components.

        This method does nothing if the resource is not in LoadStatus.LOADING state.

        Specified by:
        cancelLoad in interface Loadable
      • loadAsync

        public void loadAsync()
        Description copied from interface: Loadable
        Loads the metadata of the loadable resource asynchronously.

        The load status changes from LoadStatus.NOT_LOADED to LoadStatus.LOADING. A listener can be added via Loadable.addDoneLoadingListener(java.lang.Runnable) that is invoked upon completion of the asynchronous load operation.

        If the load operation completes successfully, the load status will be LoadStatus.LOADED, which means the resource has loaded its metadata.

        If the load operation failed, the load status will be LoadStatus.FAILED_TO_LOAD and the error can be retrieved by calling Loadable.getLoadError().

        This method can be called concurrently and repeatedly, but only one attempt is ever made to perform the load operation. If a load operation is already in progress (LoadStatus.LOADING state) when loadAsync is called, it simply piggy-backs on the outstanding operation and the done loading listener added to the loadable resource is enqueued to be invoked when that operation completes. If the operation has already completed (LoadStatus.LOADED or LoadStatus.FAILED_TO_LOAD state) when loadAsync is called, the done loading listener is immediately invoked when added to the loadable resource.

        If a loadable resource has failed to load, calling loadAsync on it subsequently will not change its state. The done loading listener will be invoked immediately when added to the loadable resource. In order to retry loading the resource, Loadable.retryLoadAsync() needs to be used.

        A load operation that is in progress (LoadStatus.LOADING state) can be cancelled by calling Loadable.cancelLoad().

        Specified by:
        loadAsync in interface Loadable
      • retryLoadAsync

        public void retryLoadAsync()
        Description copied from interface: Loadable
        Loads or retries loading metadata for the object asynchronously.

        Will retry loading the metadata if the object's load status is LoadStatus.FAILED_TO_LOAD. Will load the object if it is not loaded. Will not retry to load the object if the object is loaded.

        For more details on the load process see Loadable.loadAsync().

        Specified by:
        retryLoadAsync in interface Loadable
      • addDoneLoadingListener

        public void addDoneLoadingListener​(Runnable listener)
        Description copied from interface: Loadable
        Adds a listener to the loadable resource that is invoked when loading has completed.

        The listener may be added at any point, whether the loadable resource has already completed loading or not.

        • For resources that are not loaded when the listener is added (LoadStatus is NOT_LOADED or LOADING): When the resource completes loading, the listener will be invoked on the UI thread if it is added from the UI thread, otherwise it is not guaranteed on which thread the listener is invoked.
        • For resources that are already loaded when the listener is added (LoadStatus is LOADED or FAILED_TO_LOAD): The listener will be called immediately, on the current thread.

        Alternatively, to be notified when there is any change in the load status, use the Loadable.addLoadStatusChangedListener(LoadStatusChangedListener) method instead.

        Specified by:
        addDoneLoadingListener in interface Loadable
        Parameters:
        listener - a Runnable that is invoked upon completion of the load operation
      • removeDoneLoadingListener

        public boolean removeDoneLoadingListener​(Runnable listener)
        Description copied from interface: Loadable
        Removes a done loading listener from the loadable resource.
        Specified by:
        removeDoneLoadingListener in interface Loadable
        Parameters:
        listener - the listener to be removed
        Returns:
        true if the listener was removed, otherwise false
      • addLoadStatusChangedListener

        public void addLoadStatusChangedListener​(LoadStatusChangedListener listener)
        Description copied from interface: Loadable
        Adds a LoadStatusChangedListener to the loadable resource that is invoked whenever the load status changes.

        Adding this listener on the UI thread will cause it to be invoked on the UI thread, otherwise it is not guaranteed on which thread the listener is invoked.

        The listener will not be called if added to a loadable resource that has already completed loading. To be notified when a loadable resource has completed loading, including if the resource is already loaded when the listener is added, use the Loadable.addDoneLoadingListener(Runnable) method.

        Specified by:
        addLoadStatusChangedListener in interface Loadable
        Parameters:
        listener - the LoadStatusChangedListener to be added
      • removeLoadStatusChangedListener

        public boolean removeLoadStatusChangedListener​(LoadStatusChangedListener listener)
        Description copied from interface: Loadable
        Removes a LoadStatusChangedListener from the loadable resource.
        Specified by:
        removeLoadStatusChangedListener in interface Loadable
        Parameters:
        listener - the LoadStatusChangedListener to be removed
        Returns:
        true if the listener was removed, otherwise false
