이전에 알게된 액티비티 생명주기를 따라 코드를 읽어봅시다.

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // 상태바를 안보이도록 합니다.
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        // 화면 켜진 상태를 유지합니다.
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
                WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

        setContentView(R.layout.activity_main);


        ImageButton button = findViewById(R.id.take_photo);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                takePicture();
            }
        });

        mSurfaceView = findViewById(R.id.surfaceView);
        mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        mMagnetometer = mSensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD);
        deviceOrientation = new DeviceOrientation();

        initSurfaceView();



    }

위 코드는 액티비티가 생성될 때 실행되는 onCreate()메소드입니다. 

getWindow()메소드는 화면의 꺼짐, 켜짐과 관련된 메소드로 액티비티 클래스에 종속되어 있다고 합니다. 주석과 같이 해당 기능을 적용해주기 위해 플래그를 set해줍니다.

setContentView()는 .java 와 .xml을 이어주는 메소드라고 생각하시면 됩니다. 파라미터에 xml 경로가 들어가는군요 #1에 있던 activity_main.xml입니다. 

그 다음 줄은 버튼의 기능을 설정해주는데 xml의 id값으로 버튼을 특정할 수 있습니다. 그 id값과 .java의 변수를 연동시켜주는 것이 findViewById메소드입니다. take_photo 아이디를 가진 버튼의 기능이 설정하기 위해 OnClickListener를 달아줍니다. 그 안에 클릭되었을때의 기능을 설정하기 위해 onClick메소드가 있군요 따라서 위 코드는 take_photo 아이디를 가진 버튼이 클릭되었을 때 takePicture()메소드가 실행됩니다.

    public void takePicture() {

        try {
            CaptureRequest.Builder captureRequestBuilder = mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_STILL_CAPTURE);
            captureRequestBuilder.addTarget(mImageReader.getSurface());
            captureRequestBuilder.set(CaptureRequest.CONTROL_AF_MODE, CaptureRequest.CONTROL_AF_MODE_CONTINUOUS_PICTURE);
            captureRequestBuilder.set(CaptureRequest.CONTROL_AE_MODE, CaptureRequest.CONTROL_AE_MODE_ON_AUTO_FLASH);


            // 화면 회전 안되게 고정시켜 놓은 상태에서는 아래 로직으로 방향을 얻을 수 없어서
            // 센서를 사용하는 것으로 변경
            //deviceRotation = getResources().getConfiguration().orientation;
            mDeviceRotation = ORIENTATIONS.get(deviceOrientation.getOrientation());
            Log.d("@@@", mDeviceRotation+"");

            captureRequestBuilder.set(CaptureRequest.JPEG_ORIENTATION, mDeviceRotation);
            CaptureRequest mCaptureRequest = captureRequestBuilder.build();
            mSession.capture(mCaptureRequest, mSessionCaptureCallback, mHandler);
        } catch (CameraAccessException e) {
            e.printStackTrace();
        }
    }

 촬영관련은 디바이스와 호환이 요구되므로 트라이 캐치문으로 감싸주고 촬영 관련 클래스인 CaptureRequest.Builder를 생성해줍니다. 타겟을 설정해주고 모드를 설정해줍니다. 

mDeviceRotation은 스마트폰을 회전시킬 때 스마트폰 내 센서(가속도계, 자이로센서)를 이용해 각도를 알아내 입력하는 변수입니다. 즉, deviceOrientation에 센서를 이용한 코드가 담겨있죠. 글이 너무 길어지므로 이 내용은 #3-1에서 다루겠습니다.

캡쳐리퀘스트 빌더에 jpeg 포맷 정보와 각도 정보를 설정해주고 빌드해줍니다. 그리고 현재 세션에 서페이스 스레드와 함께 캡쳐 리퀘스트를 설정해줍니다. 이때 콜백함수도 같이 넘겨주는데 콜백함수는 아래와 같이 촬영 성공, 실패, 촬영 중의 경우 기능으로 구성되어 있습니다.

private CameraCaptureSession.CaptureCallback mSessionCaptureCallback = new CameraCaptureSession.CaptureCallback() {
        @Override
        public void onCaptureCompleted(CameraCaptureSession session, CaptureRequest request, TotalCaptureResult result) {
            mSession = session;
            unlockFocus();
        }

        @Override
        public void onCaptureProgressed(@NonNull CameraCaptureSession session, @NonNull CaptureRequest request, @NonNull CaptureResult partialResult) {
            mSession = session;
        }

        @Override
        public void onCaptureFailed(@NonNull CameraCaptureSession session, @NonNull CaptureRequest request, @NonNull CaptureFailure failure) {
            super.onCaptureFailed(session, request, failure);
        }
    };

이전 포스트들은 다소 굵직한 메소드 및 객체들을 소개했습니다. 이제 액티비티 생명주기에 맞춰 코드를 읽어봅시다. 그전에 액티비티 생명주기부터 알아야겠죠?

액티비티 생명주기:

1. onCreate()

Activity가 처음 만들어질 때 호출되는 함수이면서, 어플리케이션이 처음 시작할 때 최초로 한번 실행되는 함수이다. 주로 view를 만들거나 view resource bind , data to list 등을 onCreate()에서 담당하며, 이전 상태의 정보를 담고있는 Bundle을 제공한다.

2. onStart()

Activity가 다시 시작되기 전에 호출, Actvitiy가 멈춘 후 호출되는 함수, Activity가 사용자에게 보여지기 직전에 호출되는 함수

3. onResume()

Activity가 비로소 화면에 보여지는 단계, 사용자에게 Focus를 잡은 상태

3-1 onRestart()

Activity가 멈춰있다가 다시 호출될 때 불리는 함수, 즉 Stopped상태였을 때 다시 호출되어 시작될 때 불린다.

---------- 다른 Activity가 호출 되는 경우 ---------- 

4. onPause()

 Activity위에 다른 Activity가 올라와서 focus를 잃었을 때 호출되는 함수. 

 완전 Activity가 가려지지 않은 상태에서 호출되는 함수.

 즉 일부분이 보이거나 투명상태일 경우 호출된다.

 다른 Activity가 호출되기 전에 실행되기 때문에 onPause()함수에서 시간이 많이 소요되는 작업이나, 

 많은 일을 처리하면, 다른 Activity가 호출되는 시간이 지연되기 때문에 많은 일을 처리하지 않도록 주의하자.

 영구적인 data는 여기서 저장한다.

5. onStop()

Activity위에 다른 Activity가 완전히 올라와 화면에서 100% 가려질 때 호출되는 함수. 홈키를 누르는 경우. 

또는 다른 액티비티페이지 이동이 있는 경우. 만약 이상태에서 Activity가 다시 불려지면, onRestart()함수가 호출된다.

6. onDestroy()

Activity가 완전히 스택에서 없어질 때 호출되는 함수, 즉 제거되는 경우. 

finish() 메소드가 호출되거나, 시스템 메모리 확보를 위해 호출된다.

*onStop(), onDestroy() 함수는 호출되지 않을 수 있음.

예) 메모리 부족으로 인해 onStop()을 안 탈 수 있다.
