Use Google Maps maps in Maverick
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.
