/** 
* This sample illustrates the use of ArcGISLocatlTiledLayer where the data is stored locally on the device, therefore  
* this layer can function even when the device does not have any network connectivity. The data for this layer must be  
* in an ArcGIS Compact Cache format or packaged as a Tile package (*.tpk). 
*  
* The typical compact cache structure is as  follows: 
*   <CacheName><br> 
*       Layers<br> 
*           _allLayers<br> 
*               conf.cdi,conf.xml<br> 
* The path used in the constructor of the ArcGISLocalTiledLayer must point to the Layers folder e.g. <br> 
*  ArcGISLocalTiledLayer local = new ArcGISLocalTiledLayer("file:///mnt/sdcard/<CacheName>/Layers"); 
*   
*  A sample data set has been created and is available via ArcGIS Online: 
*  http://www.arcgis.com/home/item.html?id=d2d263a280164a039ef0a02e26ee0501 
*  1) In order to use the data, download it from the url above 
*  2) Copy the data to your sdcard 
*  3) Set the path to the data by replacing <Path-to-local-data> with file:///mnt/sdcard/Parcels/v101/Parcel Map 
*     on line68 below. 
*   
*  A sample Tile Map Package has been created and is available via ArcGIS Online: 
*  http://www.arcgis.com/home/item.html?id=4497b7bb42e543b691027840d1b9092a 
*  1) In order to use the data, download it from the url above 
*  2) Copy the data to your device 
*  3) Set the path to the *.tpk file by replacing <Path-to-local-data> on line 68 below 
*   
*  You can also use your own data if it is in an ArcGIS Compact Cache format, for more information on  
*  this data format see this link:  
*  http://blogs.esri.com/Dev/blogs/arcgisserver/archive/2010/05/27/Introducing-the-compact-cache-storage-format.aspx
