How to make the android app offline using Google maps? or download the Map area in Android app using Google maps for an offline use?

Question

I am making a navigation app and have done all the work for which internet is required. I mean (I have drawn markers, made a route between them and other facilities like searching places of interest with reference to the users location) etc etc using Google map Android API v2.

But now I want to make that app offline too. I mean so that the user can do these things without internet connections. If search facility is possible in offline mode (I mean if markers cannot be drawn, route cannot be made between start and destination) then please tell me how it is possible.

And if it is not possible then how can I download the whole area of the map which shows the route the user has made using the app in online mode?

Answer 1

Here is an article talking about offline maps for iOS and Android .
You could save the maps you want and work on the saved map files for your project.

This is the latest version of Google Maps for Android, download it and scroll to the bottom of the page to find a section dedicated to offline maps. You can now save a map by:

1. Typing "OK Maps" while viewing any map.
2. In the settings menu.

Note that this only saves maps for 30 days.

Answer 2

You can use an OpenStreetMaps controller and Google Maps tiles. According to the Google Maps TOS (10.1.3.b), it seems that you can use a portion of maps if you cache it temporarily and securely.
