I am just beginning to learn android, but could not get proper idea, how to handle this, so I want to store every 2 minute location coordinate if i travel in bus.
What i am using:
public class AndroidGPSTrackingActivity extends Activity {
Button btnShowLocation;
// GPSTracker class
GPSTracker gps;
TextView tv;
ArrayList<String> cordsList= new ArrayList<String>();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv=new TextView(this);
btnShowLocation = (Button) findViewById(R.id.btnShowLocation);
btnShowLocation.setText("Start Save Location");
Log.i("Finall", "AndroidGPSTrackingActivity-> ");
// show location button click event
btnShowLocation.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// create class object
gps = new GPSTracker(AndroidGPSTrackingActivity.this);
// check if GPS enabled
if(gps.canGetLocation()){
double latitude = gps.getLatitude();
double longitude = gps.getLongitude();
String longlat=String.valueOf(latitude)+":"+String.valueOf(longitude);
cordsList.add(longlat);
// \n is for new line
Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG).show();
}else{
// can't get location
// GPS or Network is not enabled
// Ask user to enable GPS/network in settings
gps.showSettingsAlert();
}
Log.i("Finall", "Location-> "+cordsList.toString());
}
});
}
I am getting on time but could not get every 30 and where to store.
public class GPSTracker extends Service implements LocationListener {
private final Context mContext;
// flag for GPS status
boolean isGPSEnabled = false;
// flag for network status
boolean isNetworkEnabled = false;
// flag for GPS status
boolean canGetLocation = false;
Location location; // location
double latitude; // latitude
double longitude; // longitude
// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters
// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 2; // 2 minute
// Declaring a Location Manager
protected LocationManager locationManager;
public GPSTracker(Context context) {
this.mContext = context;
getLocation();

Hello , every body, any idea, If i travel bus and my gps on then i travel 20 minute, then i want to save 10 co-ordinate in arrays. Any idea, how to do this. and stop after clicking STOP button.
Thanks in Adavance.
You are can use the Timer
class in android which will give you the TIME_INTERVAL
to call that class .In your case you can give the TIME_INTERVAL = 20000
Here is my example code :
public class MainActivity extends Activity {
Timer timer = new Timer();
GpsTracker gpsTracker ;
ArrayList<Double> arrLat= new ArrayList<Double>();
ArrayList<Double> arrLng = new ArrayList<Double>();
private final int TIME_INTERVAL = 20000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gpsTracker = new GPSTracker(this);
timer.scheduleAtFixedRate(new TimerTask() {
@SuppressLint("DefaultLocale")
@TargetApi(Build.VERSION_CODES.GINGERBREAD)
@Override
public void run() {
latitude = GPSTracker.getLatitude();
longitude = GPSTracker.getLongitude();
System.out.println("lat------ "+latitude);
System.out.println("lng-------- "+longitude);
arrLat.add(latitude);
arrLng.add(longitude);
}
}, 0, TIME_INTERVAL);
}
}
