Я пытался получить значения долготы и широты с помощью GPS-приемника Blackberry.Мое устройство - факел ежевики.Симулятор, который я использую, также является факелом ежевики.Слушатель GPS, кажется, работает на симе, но однажды на реальном устройстве это терпит неудачу.Когда я говорю сбой, он не собирает значения долготы и широты, скорее, он даже пытается подключиться к GPS.Я проверил свое меню параметров и смог выбрать значения long и lat из настроек местоположения, так почему мое приложение не сможет это сделать?Я вызываю класс handleGPS в другом классе, то есть, делая это:
new handleGPS();
Как я уже сказал, используя SIM I, провайдер находит мое местоположение примерно через 10 секунд.На реальном устройстве я отлаживаю его, и он достигает этого утверждения (поскольку печатаются System.out)
try {
lp = LocationProvider.getInstance(cr);
System.out.println("location Provider");
lp.setLocationListener(new handleGPSListener(), 10, -1, -1);
//lp.setLocationListener(listener, interval, timeout, maxAge)
System.out.println("location Provider after listener");
} catch (LocationException e) {
e.printStackTrace();
}
Однако никакие значения не возвращаются.Ниже мой код.
Класс GPS:
public class handleGPS extends TimerTask {
//Thread t = new Thread(new Runnable() {
private Timer timer;
LocationProvider lp = null;
public handleGPS()
{
timer =new Timer();
System.out.println("timer");
GPS();
//timer.schedule(this, 0, 10000);
timer.schedule(this, 1000);
}
public void GPS() {
Criteria cr = new Criteria();
cr.setHorizontalAccuracy(Criteria.NO_REQUIREMENT);
cr.setVerticalAccuracy(Criteria.NO_REQUIREMENT);
cr.setCostAllowed(false);
cr.setPreferredPowerConsumption(Criteria.NO_REQUIREMENT);
//cr.setPreferredResponseTime(1000);
System.out.println("GPS ()");
try {
lp = LocationProvider.getInstance(cr);
System.out.println("location Provider");
lp.setLocationListener(new handleGPSListener(), 10, -1, -1);
//lp.setLocationListener(listener, interval, timeout, maxAge)
System.out.println("location Provider after listener");
} catch (LocationException e) {
e.printStackTrace();
}
}
// });
public void run() {
// TODO Auto-generated method stub
lp.setLocationListener(new handleGPSListener(), 10, -1, -1);
}
}
