Invalid Path for Map Layer when using ArcGISLocalTiledLayer

[LukeCatania]

I loaded a map cache in genymotion emulator.  When I run the app, I receive the following error

url =/storage/emulated/0/ArcGIS/SAGE/LocalNetwork/SanFrancisco/basemap/Basemap/_alllayers is invalid path.

I am using the OfflineRoutingAndGeocoding sample app and modifying it. 

final String tpkPath = "/ArcGIS/SAGE/LocalNetwork/SanFrancisco/basemap/Basemap/_alllayers";
mTileLayer = new ArcGISLocalTiledLayer(extern + tpkPath);

The map cache I create is from the File/ShareAs/Runtime content... in ArcMap.

If I comment out the lines for the map background to just see the network, it doesn't show up because the background is black. I assume the streets are drawn in black.  How can I change the background color to white or the streets to another color to make sure the network is loading.

Error on my part with the path.  That part is fixed.  Error I get now is:

java.lang.RuntimeException: Error reading cache configuration!

Well even though the documentation at:

https://developers.arcgis.com/android/api-reference/reference/com/esri/android/map/ags/ArcGISLocalTi...

shows an example of how to acess the cache as:

ArcGISLocalTiledLayer local = new ArcGISLocalTiledLayer("/sdcard/<CacheName>/Layers");

I changed it to:

ArcGISLocalTiledLayer local = new ArcGISLocalTiledLayer("/sdcard/<CacheName>");

and it worked.  My layers subdirectory is actually called "_alllayers".  I supposed maybe it just looks one directory below what you specify looking for L## subdirectories.  Then I though maybe it looks in the conf.xml or conf.cdi files for a path to the bundles, but those files do not contain that info.  Not every cache built would have the "_alllayers" designation as I remember.  A user can change the "Layers" name in ArcMap TOC which I thought is what determines how that is named when building a cache from a map service.  I think my map was designated "_alllayers" because it was created using the runtime content option basemap option.  Unless something changed with how that directory is named in 10.2.2.
