java - 目录创建失败... Java，Android

我正在尝试将我用我的应用拍摄的照片保存到特定目录。它正在工作，但我已接近完成应用程序，并希望尝试全新安装。我删除了保存照片的文件夹，现在它不会重新制作。这是我的代码。

 PictureCallback jpegCallback = new PictureCallback() { // 
     public void onPictureTaken(byte[] data, Camera camera) {
       FileOutputStream outStream = null;
       try {      
                 android.os.Environment.getExternalStorageState();
            // create a File object for the parent directory
              File PhotoDirectory = new File(
                      android.os.Environment.getExternalStorageDirectory()+
                      "/GrowJournalPhotos/"+journ_id+"/"+plant_id+"/");
        // have the object build the directory structure, if needed.
        PhotoDirectory.mkdirs();
        // create a File object for the output file
        File outputFile = new File(PhotoDirectory, "photo.jpg");
        // now attach the OutputStream to the file object, instead of a String representation
        outStream = new FileOutputStream(outputFile);    //----LINE 82----//

         // Write to SD Card
         outStream.write(data);
         outStream.close();
         Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length);
         setResult(RESULT_OK);
            finish();

       } catch (FileNotFoundException e) { // 
         e.printStackTrace();
       } catch (IOException e) {
         e.printStackTrace();
       } finally {
       }
       Log.d(TAG, "onPictureTaken - jpeg");
     }
   };

IO错误：

我确实将权限设置为写入外部存储。如果我手动创建目录，在计算机上安装驱动器并创建第一个文件夹“/ sdcard / GrowJournalPhotos /”，其他一切都可以正常工作。必要时，确实需要确保应用程序将创建整个目录。
