Android GPS cloud of confusion!
- by Anthony Forloney
I am trying to design my first Android application with the use of GPS. As of right now, I have a drawable button that when clicked, alerts a Toast message of the longitude and latitude. I have tried to use the telnet localhost 5554 and then geo fix #number #number to feed in values but no results display just 0 0. I have also tried DDMS way of sending GPS coordinates and I get the same thing.
My question is what exactly is the code equivalent to the geo fix and the DDMS way of sending coordinates. I have used Location, LocationManger and LocationListener but I am not sure which is the right choice.
Could anyone explain to me what the code-equivalent just so I can get a better understanding of how to fix my application not working. Code is given, just in case if the error exists with the code
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button) findViewById(R.id.track);
button.setOnClickListener(this);
LocationManager location =(LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location loc = location.getLastKnownLocation(location.GPS_PROVIDER);
updateWithNewLocation(loc);
}
private final LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
updateWithNewLocation(location);
}
private void updateWithNewLocation(Location l) {
longitude = l.getLongitude();
latitude = l.getLatitude();
provider = l.getProvider();
}
public void onClick(View v) {
Toast.makeText(this, "Your location is " +
longitude + " and " + latitude + " provided by: " +
provider, Toast.LENGTH_SHORT).show();
}
}
