连续GPS android系统中，每x分钟跟踪即使应用程序被关闭（或强制关闭）

Question

我设计这帖子，如果（启用GPS和网络启用）的GPS坐标的Android应用程序。目前我没有编写发布数据的代码。 我已经编写了代码，用于后台服务和调用服务。通过一些教程。任何一个可以请法官这是正确的方式

     WakeLock wakeLock; 

     private LocationManager locationManager; 

     public AndroidLocationServices() {

     @Override

       } 
       try {

       if (Util.isGPSAvi() && Util.isNetAci()) { 

        // JSONArray jsonArray = new JSONArray();

        try { 
         Log.e("latitude", location.getLatitude() + ""); 
         Log.e("longitude", location.getLongitude() + ""); 

         Toast.makeText(
           getApplicationContext(),

        } catch (Exception e) { 
         // TODO Auto-generated catch block 
         e.printStackTrace(); 
         Toast.makeText(getApplicationContext(), "In Exp "+e.getMessage(), 
           Toast.LENGTH_SHORT).show(); 
        } 

       } 

      } 

      @Override 
      public void onProviderDisabled(String provider) { 
       // TODO Auto-generated method stub 
    Toast.makeText(getApplicationContext(), "onProviderDisabled",Toast.LENGTH_LONG).show(); 
      } 

      @Override 
      public void onProviderEnabled(String provider) { 
       // TODO Auto-generated method stub 
       Toast.makeText(getApplicationContext(), "onProviderEnabled",Toast.LENGTH_LONG).show(); 

      } 

      @Override 
      public void onStatusChanged(String provider, int status, Bundle extras) { 
       // TODO Auto-generated method stub 
       Toast.makeText(getApplicationContext(), "onStatusChanged",Toast.LENGTH_LONG).show(); 

      } 
     }; 

     @Override 
     public void onDestroy() { 
      // TODO Auto-generated method stub 
      super.onDestroy(); 
      Toast.makeText(getApplicationContext(), "onDestroy",Toast.LENGTH_LONG).show(); 
      wakeLock.release(); 

     } 

    // public static boolean isConnectingToInternet(Context _context) { 
    //  ConnectivityManager connectivity = (ConnectivityManager) _context 
    //    .getSystemService(Context.CONNECTIVITY_SERVICE); 
    //  if (connectivity != null) { 
    //   NetworkInfo[] info = connectivity.getAllNetworkInfo(); 
    //   if (info != null) 
    //    for (int i = 0; i < info.length; i++) 
    //     if (info[i].getState() == NetworkInfo.State.CONNECTED) { 
    //      return true; 
    //     } 
    // 
    //  } 
    //  return false; 
    // } 



    } 

而且在开始屏幕应用程序登录按钮的onClick

@Override 
public void onClick(View v) { 

    startService(new Intent(this, AndroidLocationServices.class)); 

    And starting intent to go for another screen 


} 

和清单的文件

<service 
     android:name="com.xxx.gps.AndroidLocationServices" 
     android:enabled="true" />

有没有办法让服务运行在如果用户强制关闭或关闭应用程序，则为背景。

为了提高不被杀害的服务的机会时，在内存不足的系统运行，我会建议使它foreground。您还需要将其设置为前景以避免在Android棉花糖中暂停（请参阅Power-Saving Optimizations）。

您还可以看看Traccar Client open source GPS tracking app。你可以将它作为你的应用的基础，或者只是从那里借鉴一些想法。
