Skobbler Sdk 3.0.2: Prebundled Map

I'm using Skobbler SDK 3.0.2 and I can't load prebundled map. I prepared the map package for prebundling (SKMaps.zip) following instruction in https://developer.skobbler.com/getti

Solution 1:

From here you can download a modified 3.0.2 Android demo project with the city of Stuttgart (Germany) used as a prebundle map.

Solution 2:

I had this problem when putting SKMaps.zip into assets folder with zipped subfolder /SKMaps/ .. Make sure your zip contains only subfolders and files - not another SKMaps folder
