SMS로 사진 찍기

Question

나는이 액티비티 (MakePhotoActivity) 클래스를 사용하여 애플리케이션을 열 때 사진을 찍습니다. 전방 향 카메라를 사용하도록 설정했습니다.

그렇다면 이미 다른 클래스가 있습니다.이 클래스는 이미 작동중인 SMS 브로드 캐스트 수신기입니다.

이제 SMS를 받으면 현재 수업을 사용하여 사진을 찍고 싶습니다. 그러나 어떻게 그들을 함께 통합 할 수 있습니까?

내 방송 수신기 클래스에 메서드 (surfaceChanged 등)를 복사 해보고 sms가 수신함에 따라 onCreate (MakePhotoActivity)에있는 코드를 배치했습니다. 그리고 그것은 작동하지 않습니다.

public class MakePhotoActivity extends Activity implements SurfaceHolder.Callback 
{ 
    //a variable to store a reference to the Image View at the main.xml file 
    private ImageView iv_image; 
    //a variable to store a reference to the Surface View at the main.xml file 
    private SurfaceView sv; 

    //a bitmap to display the captured image 
    private Bitmap bmp; 
    private int cameraId = 0; 

    //Camera variables 
    //a surface holder 
    private SurfaceHolder sHolder; 
    //a variable to control the camera 
    private Camera mCamera; 
    //the camera parameters 
    private Parameters parameters; 


    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 


     //get the Image View at the main.xml file 
     iv_image = (ImageView) findViewById(R.id.imageView); 

     //get the Surface View at the main.xml file 
     sv = (SurfaceView) findViewById(R.id.surfaceView); 

     //Get a surface 
     sHolder = sv.getHolder(); 

     //add the callback interface methods defined below as the Surface View callbacks 
     sHolder.addCallback(this); 

     //tells Android that this surface will have its data constantly replaced 
     sHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); 
    } 

    private int findFrontFacingCamera() { 
     int cameraId = -1; 
     // Search for the front facing camera 
     int numberOfCameras = Camera.getNumberOfCameras(); 
     for (int i = 0; i < numberOfCameras; i++) { 
      CameraInfo info = new CameraInfo(); 
      Camera.getCameraInfo(i, info); 
      if (info.facing == CameraInfo.CAMERA_FACING_FRONT) { 
       Log.d("A", "Camera found"); 

       cameraId = i; 
       break; 
      } 
     } 
     return cameraId; 
    } 

    public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) 
    { 
     //get camera parameters 
     parameters = mCamera.getParameters(); 

     //set camera parameters 
     mCamera.setParameters(parameters); 
     mCamera.startPreview(); 

     //sets what code should be executed after the picture is taken 
     Camera.PictureCallback mCall = new Camera.PictureCallback() 
     { 

      public void onPictureTaken(byte[] data, Camera camera) 
      { 
       //decode the data obtained by the camera into a Bitmap 
       bmp = BitmapFactory.decodeByteArray(data, 0, data.length); 
       //set the iv_image 
       iv_image.setImageBitmap(bmp); 
       FileOutputStream outStream = null; 
       try{ 
        outStream = new FileOutputStream("/sdcard/Image"+System.currentTimeMillis()+".jpg"); 
        outStream.write(data); 
        outStream.close(); 
       } catch (FileNotFoundException e){ 
        Log.d("CAMERA", e.getMessage()); 
       } catch (IOException e){ 
        Log.d("CAMERA", e.getMessage()); 
       } 
      } 
     }; 

     mCamera.takePicture(null, null, mCall); 
    } 


    public void surfaceCreated(SurfaceHolder holder) 
    { 
     // The Surface has been created, acquire the camera and tell it where 
     // to draw the preview. 

     if (mCamera == null) { 
      cameraId = findFrontFacingCamera(); 
      mCamera = Camera.open(cameraId); 
      try { 
       mCamera.setPreviewDisplay(holder); 

       // TODO test how much setPreviewCallbackWithBuffer is faster 
       // mCamera.setPreviewCallback((PreviewCallback) this); 
      } catch (IOException e) { 
       mCamera.release(); 
       mCamera = null; 
      } 
     } 
    } 


    public void surfaceDestroyed(SurfaceHolder holder) 
    { 
     if (mCamera != null) { 
      mCamera.stopPreview(); 
      mCamera.setPreviewCallback(null); 
      mCamera.release(); 
      mCamera = null; 
     } 
    } 

    @Override 
    protected void onDestroy() { 
     // TODO Auto-generated method stub 
     super.onDestroy(); 
     if (mCamera!=null) 
     { 
      mCamera.stopPreview(); 
      mCamera.release(); 
      mCamera=null; 
     } 
    } 
} 

업데이트 : 이것은 내가 한 것입니다. 서비스에 넣어,하지만 응용 프로그램이 NULL 표면을 통과했다는 오류가 발생, 카메라 서버가 죽었다 !, ICamera가 사망, 오류 100.

나는 http://easyandroidtutorials.blogspot.in/2012/09/capture-image-without-preview-as.html에서 코드를 참조하고 약간의 변화를 만들었지 만 여전히 작동하지 않습니다.

    SurfaceView sv; 
    private int cameraId = 0; 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate()

        mCamera = Camera.open(cameraId); 

       try { 
        // Thread.sleep(3000); 
        sv = new SurfaceView(getApplicationContext()); 
        mCamera.setPreviewDisplay(sv.getHolder()); 
        parameters = mCamera.getParameters();

이 작업을 수행 :

Intent intent = new Intent(this, MakePhotoActivity.class); 
startActivity(intent);
