如何在gcmbaseintentservice中获取位置

Question

我想在接收邮件时获取位置。
所以我使用GCM服务，但它不适用于LocationListener。
是否可以在GCMBaseIntentService中使用LocationListener？如果不是，我可以使用什么？

这里是我的源代码：

@Override 
public void onMessage(Context context, Intent intent) { 
    String type = intent.getStringExtra("type"); 
    String fromId = intent.getStringExtra("fromId"); 
    String fromNumber = intent.getStringExtra("fromNumber"); 
    final String address; 

    if(type.equals("request_position")){ 
     if(hasId(context, fromNumber)){ 
      Message message = new Message(); 
      message.obj = intent; 
      MyService.handler.sendMessage(message); 
     }else{ 
      String addressStr = "사용자의 친구가 아닙니다."; 
      new SendMessage().execute("response_position",fromId,Info.get(context).getRegId(),addressStr); 
     } 
    }else if(type.equals("response_position")){ 
     address = intent.getStringExtra("address"); 

     Handler handler = new Handler(Looper.getMainLooper()); 
     handler.post(new Runnable() { 
      public void run() { 
        FindPhoneFragment.resultTv.setText(address); 
      } 
     }); 
    } 


} 



public class MyLocation { 
private Context context; 
private LocationManager manager; 
private MyLocationListener listener; 
private Location location; 
private long minTime = 1000; 
private float minDistance = 1; 
private String fromId; 

public MyLocation(Context context){ 
    this.context = context; 
    manager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE); 
    listener = new MyLocationListener(); 
} 
public void getMyLocation(String fromId){ 



    manager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, minTime, minDistance, listener); 
    manager.requestLocationUpdates(LocationManager.GPS_PROVIDER, minTime, minDistance, listener); 
} 
public void sendLocation(Location location){ 

    Geocoder geocoder = new Geocoder(context ,Locale.KOREA); 
    List<Address> address; 

    Double latitude; 
    Double longitude; 
    latitude = location.getLatitude(); 
    longitude = location.getLongitude(); 
    String addressStr; 

    try{ 
     if(geocoder !=null){ 
      address = geocoder.getFromLocation(latitude, longitude, 1); 
      if(address != null && address.size() > 0){ 
       addressStr = address.get(0).getAddressLine(0).toString(); 
       new SendMessage().execute("response_position",fromId,Info.get(context).getRegId(),addressStr); 
      }else{ 
       Log.d("GCM", "좌표없음"); 
      } 
     } 
    }catch(IOException e){ 
     //TODO 
    } 


} 

class MyLocationListener implements LocationListener{ 
    @Override 
    public void onLocationChanged(Location location) { 
     sendLocation(location); 
     manager.removeUpdates(listener); 
    } 

    @Override 
    public void onProviderDisabled(String provider) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void onProviderEnabled(String provider) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void onStatusChanged(String provider, int status, Bundle extras) { 
     // TODO Auto-generated method stub 

    } 

} 




} 


public class Util { 

private static Util sUtil; 
private Context mAppContext; 
private MyLocation myLocation; 


private Util(Context appContext){ 
    mAppContext = appContext; 
    myLocation = new MyLocation(appContext); 
} 


public static Util get(Context c){ 
    if(sUtil == null) 
     sUtil = new Util(c.getApplicationContext()); 
    return sUtil; 
} 



public MyLocation getLocation(){ 
    return myLocation; 
} 

    } 



public class MyService extends Service { 
public static Handler handler = new Handler(){ 

    @Override 
    public void handleMessage(Message msg) { 
     Intent intent = (Intent)msg.obj; 
     onMessage(intent); 
    } 

    public void onMessage(Intent intent){ 
     String fromId =intent.getStringExtra("fromId"); 
     Util.get().getLocation().getMyLocation(fromId); 
    } 

}; 

@Override 
public IBinder onBind(Intent intent) { 
    // TODO Auto-generated method stub 
    return null; 
}

IntentService是保持有效，只要它需要的服务。在GCM情况下，它可能会在处理完消息后自行停止。
您可以阅读更多关于它here。
如果您将IntentService注册为该位置的侦听器，那么当locationManager尝试调用侦听器时，它将不再存在，这意味着您无法获取位置。

至于你的代码，我建议你创建一个经常在后台运行的​​。当您收到gcm消息时，您将其转移到服务并在那里处理。
传输消息的方式可以通过在服务（而不是在IntentService）上创建一个Handler来完成。处理程序的好处在于，它们在创建它们的线程中执行代码。这意味着您将在活着的上下文中运行代码。

的gCMBaseIntentService类：

public class gCMBaseIntentService extends GCMBaseIntentService{ 
    public ActivityRecognitionIntentService() { 
     super("ActivityRecognitionService"); 
    } 

    @Override 
    public void onMessage(Context context, Intent intent) { 
     Message message = new Message(); 
     message.obj = intent; 
     MyService.handler.sendMessage(message); 
    } 
} 

新的服务：

public class MyService extends Service { 
    public static Handler handler = new Handler() { 
      @Override 
      public void handleMessage(Message msg) { 
       Intent intent = (Intent) msg.obj; 
       onMessage(this, intent); 
      } 
     }; 

    public void onMessage(Context context, Intent intent) { 
     ... your original onMessage goes here ... 
    } 

}
