Making indoor localization based on Wi-Fi as easy as outdoor localization for Android...
Just call:
public void locateMe()
And use a callback to receive the location:
@Override
public void onLocationChanged(String location) {
//display location
Toast t = Toast.makeText(this.getApplicationContext(), "Location: " + location,Toast.LENGTH_SHORT);
t.setGravity(Gravity.CENTER, 0, 0);
t.show();
Log.d("LOCATION", "LOCATION: " + location);
}
