Hello,
I am in the same situation. I try to display in an Android application a .tpk file.
Can you, please, help me with some advice. How did you succeeded to display the .tpk file? How did you said above, right now I have only a blank white screen with Esri logo in bottom-right corner and nothing else.
The code is below:
String base = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)+
"/myTPKFile.tpk";
TileCache tileCache = new TileCache(base);
ArcGISTiledLayer tiledLayer = new ArcGISTiledLayer(base);
Basemap basemap = new Basemap(tiledLayer);
ArcGISMap map = new ArcGISMap(basemap);
mmapView.setMap(map);
Thank you,
