title: android Maps API v2 with custom markers
body: <p>I want to make maps with custom markers. In API v2 I can set icon, title, etc for markers. But I want to display title with marker at the first onset. Now title displays only when I taping the marker. In v1 was overlays, but in v2 I didn't found anything similar.</p>
  
  <p><strong>Edited:</strong>
  Maybe I was not clear enough. Something like <code>Marker.showInfoWindow()</code> in API works only for one marker. I can't show info windows for all of my markers at the same time. Anyway I need to show titles for all of my markers, without waiting while user will tap on it.</p>
