Good afternoon, I try to send the received GPS-координаты to the server, if they are output to the console, then everything is fine, but when I try to send them to the server, the application crashes.

 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); } protected void onResume() { super.onResume(); if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission. See the documentation // for ActivityCompat#requestPermissions for more details. return; } locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER/*ТИП ПРОВАЙДЕРА*/,// НА ВХОД ЕМУ ПОДАЁМ 1000 * 10/*МИНИМАЛЬНОЕ ВРЕМЯ ЗАПРОСА КООРДИНАТ*/, 10/*РАСТОЯНИЕ ОТОЙДЯ НА КОТОРОЕ ОБНОВЛЯЮТСЯ КООРДИНАТЫ*/, locationListener); } @Override protected void onPause() {//ОТКЛЮЧАЕМ СЛУШАТЕЛЯ МЕТОДА removeUpdates super.onPause(); if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission. See the documentation // for ActivityCompat#requestPermissions for more details. return; } locationManager.removeUpdates(locationListener); } private LocationListener locationListener = new LocationListener() { @Override public void onLocationChanged(Location location) { showLocation(location); coordinatesGPS (); } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } @Override public void onProviderDisabled(String provider) { checkDisabled1(); checkDisabled2(); } @Override public void onProviderEnabled(String provider) { } }; private void showLocation(Location location) { if (location == null) return; dataGPS1 = formatLocation1(location); dataGPS2 = formatLocation2(location); } public String formatLocation1(Location location) { if (location == null) return ""; return String.format( "%1$.4f", location.getLatitude(), location.getLongitude()); } public String formatLocation2(Location location) { if (location == null) return ""; return String.format( "%2$.4f", location.getLatitude(), location.getLongitude()); } private void checkDisabled1() { dataGPS1 = "00,0000"; } private void checkDisabled2() { dataGPS2 = "00,0000"; } public void coordinatesGPS () { String datGPS1 = dataGPS1; System.out.println("Координаты =" + datGPS1); try { //---------------------------------------------- client = new Socket("192.168.1.138"/*192.168.1.138"*/, 58000); //---------------------------------------------- DataOutputStream outData = new DataOutputStream(client.getOutputStream()); outData.writeUTF(datGPS1); } catch (IOException e) { e.printStackTrace(); } }

Mistake.

    Maybe it thus swears at the connection to the network from the main stream? - Kirill Stoianov

    Try to make a trip to the Internet from AsyncTask or Service - Kirill Stoianov

Tasks related to Internet access, it is recommended to do in the background. AsyncTask or Service, for example.

Also try:

 if (android.os.Build.VERSION.SDK_INT > 9) { StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy); }
