問題描述

我是 android 新手，最近開始學習 Android，我正在嘗試通過其唯一的 android id 獲取任何 android 設備的位置.這樣我就可以通過 GPS 或網絡提供商跟蹤大概或確切的位置.詳細地說，每當我在我的應用程序中輸入任何 Android id 時，我都可以在我的應用程序中獲取設備位置.感謝您的熱心幫助.

I am new in android and recently start learning about Android and I am trying to get location of any android device by its unique android id. By that I can track the approx or exact location either by GPS or network provider. In detail I mean to say that whenever i enter any Android id in my app i can get device location in my application. Thanks for your kind help.

終于可以用這段代碼了:

Finally I am able to do with this code:

public class MyService extends Service implements LocationListener{
String GPS_FILTER = "";
Thread triggerService;
LocationListener locationListener;
LocationManager lm;
private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meter

private static final long MINIMUM_TIME_BETWEEN_UPDATES = 1000 * 60 * 3; // 1 minute
protected LocationManager locationManager;
boolean isRunning = true;

Calendar cur_cal = Calendar.getInstance();

Location location;
double latitude; // latitude
double longitude;
UserFunctions userFunction;
private JSONObject json;
private AlertDialogManager alert = new AlertDialogManager();

private static String KEY_SUCCESS = "success";
private static String KEY_ERROR = "error";
private static String KEY_ERROR_MSG = "error_msg";
private static String KEY_FLAG = "flag";
String android_id ;
String userName;

@Override
public void onCreate() {
    // TODO Auto-generated method stub
    super.onCreate();
    Intent intent = new Intent(this, MyService.class);
    PendingIntent pintent = PendingIntent.getService(getApplicationContext(),
            0, intent, 0);
    AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    android_id = Settings.Secure.getString(getContentResolver(),
                Settings.Secure.ANDROID_ID);
    if (getAccount() != null) {
        userName = getAccount();
    }

    GPS_FILTER = "MyGPSLocation";
    // locationManager = (LocationManager)
    // getSystemService(Context.LOCATION_SERVICE);
    // locationManager.requestLocationUpdates(
    // LocationManager.GPS_PROVIDER,
    // MINIMUM_TIME_BETWEEN_UPDATES,
    // MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
    // new MyLocationListener());
    cur_cal.setTimeInMillis(System.currentTimeMillis());
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cur_cal.getTimeInMillis(),
            60 * 1000*3, pintent);
}

@Override
public void onStart(Intent intent, int startId) {
    // TODO Auto-generated method stub
    super.onStart(intent, startId);
    //turnGPSOn();
    /*Toast.makeText(getApplicationContext(), "Hello1", Toast.LENGTH_LONG)
            .show();*/
    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
     locationListener = new MyLocationListener();
     locationManager.requestLocationUpdates(
                LocationManager.NETWORK_PROVIDER,
                MINIMUM_TIME_BETWEEN_UPDATES,
                MINIMUM_DISTANCE_CHANGE_FOR_UPDATES, (LocationListener) this);
     if (locationManager != null) {
            location = locationManager
                    .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
            if (location != null) {
                latitude = location.getLatitude();
                longitude = location.getLongitude();
                /*Toast.makeText(getApplicationContext(), latitude + ", ll" + longitude, Toast.LENGTH_LONG)
