title: How to set Android Google Maps API v2 map to show whole world map?
body: <p>I am developing an android application that uses a google map in the background. When I start the application, I want to display a map of the hole word. According to the android google maps API v2: <a href="https://developers.google.com/maps/documentation/android/views" rel="noreferrer">https://developers.google.com/maps/documentation/android/views</a> the way to set a specific zoom value is "CameraUpdateFactory.zoomTo(float)" and the same api <a href="https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/CameraUpdateFactory#zoomTo(float" rel="noreferrer">https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/CameraUpdateFactory#zoomTo(float</a>) tells that the minimum argument to this function is 2.
  but when I call the function:
  mMap.moveCamera(CameraUpdateFactory.zoomTo(2));
  The viewport of the world map is just a little bigger than Australia...
  How can I display the entire world map at once?</p>
  
  <p>PS: for this experience I am using the google sample code, more specifically, the "MarkerDemoActivity.java"</p>
  
  <p>Thanks in advance, João</p>
