  3. And where is Aberdeen? What’s the latitude and longitude of Aberdeen? Bruce Scharlau, University of Aberdeen, 2010

  4. Aberdeen is west of London 57.1467°N 2.0901°W http://www.earthtools.org/ Bruce Scharlau, University of Aberdeen, 2010

  5. Use Google API for location • Select Google APIs for new projects using maps and location • Otherwise your app won’t run Bruce Scharlau, University of Aberdeen, 2010

  6. Also put permissions in manifest • Need to add permissions for • INTERNET • ACCESS_COURSE_LOCATION • ACCESS_FINE_LOCATION Bruce Scharlau, University of Aberdeen, 2010

  7. Manifest also needs to specify map library Apps with maps need to specify need as ‘true’ for com.google.android.maps library in manifest Bruce Scharlau, University of Aberdeen, 2010

  8. Map layouts need API key • Need to get Google MAPs API key to use maps in your apps – referenced in layout http://code.google.com/android/add-ons/google-apis/mapkey.html This allows map tiles to be downloaded to your application Bruce Scharlau, University of Aberdeen, 2010

  9. Direction API for routes included Can use direction API within maps API for routes http://www.anddev.org/google_driving_directions_-_mapview_overlayed-t826.html Bruce Scharlau, University of Aberdeen, 2010

  10. LocationListener updates map This is about as simple as it gets for map display http://www.vogella.de/articles/Android/article.html#locationapi Bruce Scharlau, University of Aberdeen, 2010

  14. Summary • Maps need API key to be displayed • Maps needs permissions set in manifest • Maps need API enabled • Lots of work done over network Bruce Scharlau, University of Aberdeen, 2010
