I was trying to implement a basic location based program in android and got stuck at first page itself.
This was done using a typical example using the LocationManager and LocationListener interface here is the code
public class MainActivity extends ActionBarActivity
{
MyLocationListner networkListner,gpsListner;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button start = (Button) findViewById(R.id.btn_start);
start.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
startListening();
}
});
Button stop = (Button) findViewById(R.id.btn_stop);
stop.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v)
{
stopListning();
}
});
}
public void startListening()
{
try {
LocationManager lm = (LocationManager) getSystemService(LOCATION_SERVICE);
Log.i("LocationApp","Started Listning");
networkListner = new MyLocationListner(this);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, networkListner);
} catch (Exception e) {
Log.i("myException",""+e);
}
}
public void stopListning()
{
LocationManager lm = (LocationManager) getSystemService(LOCATION_SERVICE);
if (networkListner == null)
{
lm.removeUpdates(networkListner);
networkListner = null;
}
}
public void myToast (String message)
{
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
}
Class which implements LocationListner
public class MyLocationListner implements LocationListener
{
Context ctx;
public MyLocationListner(Context context)
{
this.ctx = context;
}
private static String LOG_TAG;
@Override
public void onLocationChanged(Location location)
{
Log.i(LOG_TAG,"lattitude");
MyToast("OnLocation changeD");
String provider = location.getProvider();
double lat = location.getLatitude();
double lon = location.getLongitude();
float accuracy = location.getAccuracy();
long time = location.getTime();
MyToast(lat+"X"+lon+"Accuracy :"+accuracy);
Log.i(LOG_TAG,"lattitude :"+lat+"\nLongitude :"+lon+"\nAccuracy :"+accuracy);
}
@Override
public void onProviderDisabled(String arg0) {
Log.i(LOG_TAG,"Provider Disabled");
}
@Override
public void onProviderEnabled(String arg0) {
Log.i(LOG_TAG,"Provider Enabled");
}
@Override
public void onStatusChanged(String arg0, int arg1, Bundle arg2)
{
}
public void MyToast(String message)
{
Toast.makeText(ctx, message, Toast.LENGTH_SHORT).show();
}
}
and not a single method inside the above class is invoking , I have gone through the tutuorial two three times but still no hope!! I know I'm doing something wrong but cant find it.
I've tried running it on a real device also. Advices and answers needed Tahnks
