As mentioned in my previous post, Google recently announced a new version of Google Earth for Android. This version (22.214.171.1245) is a complete re-write of the underlying Google Earth 3D model, and now has access to unified mapping data used by Google Maps and this new version of Google Earth. This means the most current available mapping data can now be viewed in this version of Google Earth (Google Earth version 7 on all the other platforms is based on less current data). Version 8 also adds some enhanced 3D rendering and improves some aspects of KML support.
