/**
* 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:
