Android studio Android中文件的Uri？

当我在注释

outputFileDir

后，从对我不起作用的文件中提取Uri时，如果我对其进行注释，则其他方法会产生影响

如何解决

private static final String DATA_PATH = Environment.getExternalStorageDirectory().toString()+"/Tess";

strat摄像机方法不起作用为什么

private void startCameraActivity(){
        try{
            String imagePath = DATA_PATH + "/imgs";
            File dir = new File(imagePath);
            if(!dir.exists()){
                dir.mkdir();
            }
            String imageFilePath = imagePath + "/ocr.jpg";
            outputFileDir = Uri.fromFile(new File(imageFilePath));
            final Intent pictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            pictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileDir);
            if( pictureIntent.resolveActivity(getPackageManager()) != null){
                startActivityForResult(pictureIntent, REQUEST_CODE);
            }
        } catch (Exception e){
            Log.e(TAG, e.getMessage());
        }
    }
