Question

我希望在收到消息时获取位置所以我使用了GCM服务，但它不适用于LocationListener 是否可以在GCMBaseIntentService中使用LocationListener？如果没有，我可以使用什么呢？

这是我的源代码：

@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

IntentService是一种只要需要就会保持活动状态的服务。在GCM的情况下，它可能在处理消息后自行停止。
您可以阅读更多相关信息here。
如果您将IntentService注册为该位置的侦听器，则当locationManager尝试调用该侦听器时，它不再存在，意思是你没有获得位置。

至于你的代码，我建议你创建一个将在后台运行的常规Service。当您收到gcm消息时，将其转移到服务并在那里处理。
传输消息的方法可以通过在服务（而不是在IntentService）创建处理程序来完成。处理程序的好处是它们在创建它们的线程中执行代码。这意味着你将在一个活着的上下文中运行你的代码。

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 ...
    }

}
