title: Need advise on using maps within an Android App that I want to develop
body: <p>I'm considering building an Android app for my HTC phone that contains tour guides to attractions in London.  An Example, a guide that shows information about Jack The Ripper area, where the killings took place, having a start and a finish marker on a map, and a route showing areas of interest.  The user would look at the map, and follow the route from start to finish.</p>
  
  <p>Question for the more experience developer - as I've zero Android app dev experience, how easy an app does this sound?</p>
  
  <p>I was considering getting maps off the net, cropping them and customising them for each of the tour.  Can you get free maps off the web, legally? </p>
  
  <p>Or use Google Map (or something similar), and customising them to each tour.</p>
  
  <p>I hope that I've described my idea as clearly as possible, I look forward to your replies.</p>
  
  <p>p.s. this app is what I'm thinking about minus the audio at every waypoint: <a href="https://market.android.com/details?id=hu.pocketguide.bundle.London_lite&amp;feature=also_installed" rel="nofollow">https://market.android.com/details?id=hu.pocketguide.bundle.London_lite&amp;feature=also_installed</a></p>
