Playing around with offline maps and osmdroid ...

1. Download and install Mobile Atlas Creator.

2. Export tiles with the following settings:

   Mapsource: OpenStreetMap MapQuest Tile format: PNG Atlas Content: MapquestOSM

   

3. Extract the generated archive and make sure the inner folder is named MapquestOSM. Zip this folder to a file named tiles.zip. The folder structure of the archive should be like this:

└── MapquestOSM
    ├── 10
    │   └── 550
    │       └── 335.png
    ├── 11
    │   └── 1100
    │       └── 671.png
    ├── 12
    │   └── 2200
    │       └── 1343.png
    ├── 13
    │   ├── 4400
    │   │   ├── 2686.png
    │   │   └── 2687.png
    │   └── 4401
    │       ├── 2686.png
    │       └── 2687.png

Put the ZIP archive tiles.zip to the sdcard:

/mnt/sdcard/osmdroid/tiles.zip

The application will automatically find the archive and temporarily unpack the tiles as required.

For the first try there is a tiles archive in the tiles-example folder.

The application needs to be configured with the correct tile source in order to match the folder name stored in the ZIP archive. This means MapquestOSM corresponds with this map view setting:

mapView.setTileSource(TileSourceFactory.MAPQUESTOSM);

The expected folder name is specified in TileSourceFactory.java.
