В активити я использую вот такую конструкцию:
gps = new GPSTracker(StartActivity.this);
// check if GPS enabled
if(gps.canGetLocation()){
double latitude = gps.getLatitude();
double longitude = gps.getLongitude();
double altitude = gps.getAltitude();
double speed = gps.getSpeed();
double bearing = gps.getBearing();
double speedLimitA = ((10*1000)/(60*60));
// \n is for new line
Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude
+ "\nLong: " + longitude
+ "\nAlt:" + altitude, Toast.LENGTH_LONG).show();
Intent intent = new Intent(this, Logik_Activity.class);
intent.putExtra("alt",altitude);
intent.putExtra("speed",speed);
intent.putExtra("bearing",bearing);
if (speed < speedLimitA){
startActivity(intent);
}
// if speed > 0 then AAA else BBB
}else{
// can't get location
// GPS or Network is not enabled
// Ask user to enable GPS/network in settings
gps.showSettingsAlert();
}
Вам нужно соответственно вставить код не для перехода, а для отправки данных. Я к сожалению отправкой POST-запросов под Андроид не занимался - помочь пока не могу.
Сам неделю назад за Андроид сел. :) Чем богат...
Простой
