Android setResult 막히는 부분이 있어서 질문드립니다. 다시 돌아오는 부분이 너무 어려워요 ㅠ

Question

MainActivity.java (받을 activity)

case R.id.CustomGallery:

Intent customGallery = new Intent(CameraMainActivity.this , camera.Gallery.class);
startActivityForResult(customGallery,TAKE_PICTURES);

break;

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		
		if (resultCode != RESULT_OK) {
			return;
		}

		switch (requestCode) {
		
		
			
		case TAKE_PICTURES:
			if(data.getExtras().getInt("SeCd") == TAKE_PICTURE){
				Log.d("getPath",FileUtil.getStrFilePath());
				path = FileUtil.getStrFilePath();
				mContentResolver = getContentResolver();
				resultImage = (ImageView) findViewById(R.id.resultImage);
				resultImage.setImageBitmap(BitmapUtil.getBitmap(path, mContentResolver));
				break;
			}else{
				ArrayList<MultiDataParcelable> getImageList = new ArrayList<MultiDataParcelable>();
				getImageList = data.getParcelableArrayListExtra("ImageList");
				
				for(MultiDataParcelable image : getImageList){
					Log.d("Image",image.get_data());
				}
			}
			
			break;
		

 

Gallery.java

		case R.id.CameraBtn:

			doTakePhotoAction();
			
			break;

// 카메라
		public void doTakePhotoAction() {
			Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

			mImageCaptureUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "tmp_" + String.valueOf(System.currentTimeMillis()) + ".jpg"));
			intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
			
			try {
				intent.putExtra("return-data", false);
				startActivityForResult(intent, PICK_FROM_CAMERA);
			} catch (ActivityNotFoundException e) {
				e.printStackTrace();
			}
		}
		
		protected void onActivityResult(int requestCode, int resultCode, Intent data) {
			
			if (resultCode != RESULT_OK) {
				return;
			}

			switch (requestCode) {
			
			case PICK_FROM_CAMERA:
				Intent intent = new Intent(this,ImageEdditerMainActivity.class);
				FileUtil.setStrFilePath(mImageCaptureUri.getPath());
				intent.putExtra("scale", true);
				startActivityForResult(intent, TAKE_PICTURE);
				finish();
				break;
				
			case TAKE_PICTURE:
				Log.d("Gallery FilePath",FileUtil.getStrFilePath());
				Intent picture = new Intent();
				picture.putExtra("SeCd", TAKE_PICTURE);
				setResult(RESULT_OK,picture);
				finish();
				break;
			}
		}

 

ImageEdditerMainActivity.java

case R.id.CheckBtn:
			try {
				mImageCaptureUri = Uri.fromFile(BitmapUtil.SaveBitmapToFileCache((Bitmap)getBitmap(),"result_" + new File(mImagePath).getName()));
				FileUtil.setStrFilePath(mImagePath);	
			} catch (Exception e) {

			}
			setResult(RESULT_OK);
			finish();
			break;

왜 처음으로 돌아오지 않는지 막혀서 질문드려요 ㅠㅠ 여러개의 activity는 안되는건가요 ?...

마지막에 버튼 클릭하면 첨으로 오는 방법을 모르겠습니다.
