setBuiltInZoomControls on MapView

If you read the article Hello, MapView from Android, ZoomControls widget is suggested for zooming in and out of a View. MapView can automatically hook one for us by requesting it with the getZoomControls() method. But...actually it is now deprecated.

Instead of ZoomControls, MapView.setBuiltInZoomControls(true) can be used to add zoom mechanism on MapView.



Modify from previous article, AndroidLocation: with a CheckBox to toggle MapView.setSatellite().

Modify main.xml to remove SeekBar from the previous layout, and change android:clickable of com.google.android.maps.MapView to "true".

main.xml

<?xml version="1.0" encoding="utf-8"?>

Modify AndroidLocation.java, remove all myZoomBar related code, and add the code
myMapView.setBuiltInZoomControls(true);
