I use Google Maps on my PC and have some favorite places added there. On my phone, I want to use an offline map. On my old phone, I used RMaps with whole city maps downloaded with Mobile Atlas Creator and manually added favorites and POIs on it. Now I bought a new phone and found out that RMaps is no longer available.
I'd like to add favorites/POIs to Google Maps and make sure they will be available with a whole city map when the phone is offline. But I don't want to be somewhere and open Android Google Maps and find out some tile for that area wasn't downloaded.
The best solution I see is to download the whole map from Google Maps or OSM and store the map on the phone and use some app that's able to open this offline map file and at the same time sync favorites/POIs with Google Maps.
I tried OsmAnd, but when I create a POI on it, it fails due to some authentication error. It's not trying to connect to Google, because other apps are able to sync with Google Apps. But there's no setting to add login data or create a new account.
Could somebody suggest a way to properly handle offline maps and sync favorites with Google Maps?
