keytool error: java.lang.Exception: Keystore file does not exist: /.../.android/debug.keystore

A simple example using Google Maps Android API v2, step by step.
@Override
public void onLocationChanged(Location location) {
if (myLocationListener != null) {
myLocationListener.onLocationChanged(location);
double lat = location.getLatitude();
double lon = location.getLongitude();
tvLocInfo.setText(
"lat: " + lat + "\n" +
"lon: " + lon);
LatLng latlng= new LatLng(location.getLatitude(), location.getLongitude());
myMap.animateCamera(CameraUpdateFactory.newLatLng(latlng));
}
