Android位置管理器每次都返回相同的GPS座標

我正在創建一個應用程序以將電話位置發送到我的服務器。我遇到的問題是，每次啓動應用程序時，手機都會給出完全相同的GPS座標。當我重新啓動它時，座標可以改變，但是在發送第一個座標之後，它將發送相同的內容，直到應用程序重新啓動。Android位置管理器每次都返回相同的GPS座標

代碼：

// Contructor etc 

public class LocationASYNC extends AsyncTask<Activity, String, Void> { 
    private MainActivity m; 
    private LocationManager locationManager; 
    private Criteria c; 

    public LocationASYNC(MainActivity m) { 
     this.m = m; 
     locationManager = (LocationManager) m 
       .getSystemService(Context.LOCATION_SERVICE); 
     c = new Criteria(); 
     c.setAccuracy(Criteria.ACCURACY_FINE); 
     locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 
       3000, 0, m); 
    } 

// Code for finding best location provider and returning location 
    private Location findBestLocation() { 

      Location location = locationManager 
        .getLastKnownLocation(locationManager.getBestProvider(c, true)); 

      Log.v("location", 
        "provider: " + locationManager.getBestProvider(c, true)); 
      // Check if location is null 
      if (location != null) { 
       Log.v("location", "provider not null"); 
       // Test if location is more than 100 seconds old 
       if (location.getTime() < (System.currentTimeMillis() - 100000)) { 
        Log.v("location", "provider is old(GPS)"); 
        // Use network if location is more than 100 seconds (99% chance 
        // location will be gps) 
        location = locationManager 
          .getLastKnownLocation(LocationManager.NETWORK_PROVIDER); 
        // Check if network location is more then 100 seconds 
        Log.v("location", "provider: " + location.getProvider()); 
        if (location.getTime() < (System.currentTimeMillis() - 100000)) { 
         // Return null if all location data is old 
         Log.v("location", "provider is old (INT)"); 
         return null; 
        } 
       } 
       // Return location if one is less than 100 seconds old 
       return location; 
      } 
      // return null if no location is found 
      return null; 
     } 

This is the output i get from logcat:

緯度和經度是對每個日誌後催化相同，也是時間（毫秒自1980年左右。）是一樣的。

看起來像我的應用程序獲取位置一次，並沒有試圖再次獲得位置。

你在用三星手機嗎？ – Siddharth

你有答案嗎？我也有同樣的問題。 –

有沒有更新？你以前試過解決方案嗎？ – Siddharth

嘗試檢查您的設備上是否啓用了GPS，或者設備是否支持GPS。
