    The picture will be stored twice, first on gallery folder, and after on the file you especified on putExtra(MediaStore.EXTRA_OUTPUT, path) method.

    You can obtain the last picture taken doing that:

    /**
     * Gets the last image id from the media store
     * @return
     */
    private int getLastImageId(){
        final String[] imageColumns = { MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA };
        final String imageOrderBy = MediaStore.Images.Media._ID+" DESC";
        Cursor imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns, null, null, imageOrderBy);
        if(imageCursor.moveToFirst()){
            int id = imageCursor.getInt(imageCursor.getColumnIndex(MediaStore.Images.Media._ID));
            String fullPath = imageCursor.getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA));
            Log.d(TAG, "getLastImageId::id " + id);
            Log.d(TAG, "getLastImageId::path " + fullPath);
            imageCursor.close();
            return id;
        }else{
            return 0;
        }
    }
    

    This sample was based on post: Deleting a gallery image after camera intent photo taken
