Use Google Maps maps in Maverick How can I save Google Maps tiles so I can use them in Maverick offline?
I tried Mobile Atlas Creator, but it seems it does not have Google Map as a map source.
Install MapsOn by coderminus.

Go to Menu &gt; More &gt; Preferences &gt; Configure Maps and set /sdcard/maverick/tiles/Google/ or /storage/sdcard0/maverick/tiles/Google/ as the path for the tiles of Google Maps. Now you can use the "Cache area" feature of MapsOn to download the tiles of selected areas. 

Since they are stored in the Maverick folder, they are used by Maverick if you select "Google" as the map source. This also works for other map sources if you adapt the corresponding paths in MapsOn.
