연결타입 서비스

같은 프로세스 내부 Main Thread에 서비스를 만들고 Activity와 통신 

==================================================================

먼저

AndroidManifest.xml에 <service android:name=".GPService"  >라고 서비스 등록.

아래와 같이 인텐트필터를 등록해도 작동한다

            <intent-filter>

                <action android:name="com.example.GService"/>

            </intent-filter> 

==================================================================

Activity에 구현할 코드

선언

private GService mGService;

private boolean mGBound = false;   // 서비스와 연결된 상태를 점검

바인드를 끊을 때

       if(mGSBound){

      unbindService(mGConnection);

      mGBound = false;

      }

바인드를 연결할 때

    Intent intent = new Intent(MnGAActy.this, GService.class);

    bindService(intent, mGConnection, Context.BIND_AUTO_CREATE);

서버역할 중인 서비스에서 실행 결과 확인

if(mGSBound){

int intResult= mGService.getDoSomething();

String strResult= mGService.getDoSomething();

Do something what you want here!

}

서비스와 통신할 인터페이스 객체 생성

    private ServiceConnection mGConnection = new ServiceConnection(){

@Override

public void onServiceConnected(ComponentName name, IBinder service) {

        LocalBinder binder = (LocalBinder) service;

            mGService = binder.getService();

            mGBound = true;

}

    @Override

    public void onServiceDisconnected(ComponentName arg0){

    mGBound = false;

    }

    };

==================================================================

public class GService extends Service{

private static final String TAG = "GService";

private final IBinder mGBinder = new LocalBinder();

public class LocalBinder extends Binder{

GService getService(){

return GService.this;

}

}

public int getDoSomething(){

get result of some Processing

return result;

}

    @Override

    public void onCreate() 

    {

        super.onCreate();        

        Log.i(TAG, "onCreate()");

}

    @Override

    public int onStartCommand(Intent aIntent, int aFlags, int aStartId)

    {

    super.onStartCommand(aIntent, aFlags, aStartId);

    Log.i(TAG, "onStartCommand()");  

        return START_STICKY ;

    }

@Override

public void onDestroy()

{

Log.i(TAG, "onDestroy()");

}

@Override

public IBinder onBind(Intent intent) {

return mGBinder;

}

}
