獲取'供應商未啓用| ProviderError {provider ='network'}'調用'tracker.startListening（）;'即使無線網絡啓用

Question

我使用this庫，並嘗試檢索當前位置座標如下：

settings = 
       new TrackerSettings() 
         .setUseGPS(false) 
         .setUseNetwork(true) 
         .setUsePassive(true) 
         .setTimeBetweenUpdates(30 * 60 * 1000); 

     tracker = new LocationTracker(getBaseContext(), settings) { 
      @Override 
      public void onLocationFound(Location location) { 
       // Do some stuff 
       currentLatDouble = location.getLatitude(); 
       currentLngDouble = location.getLongitude(); 
      } 

      @Override 
      public void onTimeout() { 

      } 
     }; 
     tracker.startListening(); 

但是，我得到這個錯誤：

W/LocationTracker: Provider (network) 
        fr.quentinklein.slt.ProviderError: Provider is not enabled | ProviderError{provider='network'} 

設備不支持WiFi網絡提供商還是我需要編寫一些與LocationManager相關的代碼？

請讓我知道這裏有什麼問題。
