压缩图像不起作用

Question

我正在尝试使用相机上传图片。我正在将其上传到服务器

1. 点击图片并在imageview（DONE）中显示
2. 压缩要上传的图片尺寸（不工作）

3. 将图像上传到S3（使用未压缩的图像）（完成）

   这是我的onActivityResult（）

       case CAMERA_REQUEST: {
   
           Uri selectedImage = data.getData();
           String[] filePathColumn = { MediaStore.Images.Media.DATA };
   
           Cursor cursor = getContentResolver().query(selectedImage,
                   filePathColumn, null, null, null);
           cursor.moveToFirst();
   
           int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
           String picturePath = cursor.getString(columnIndex);
           cursor.close();
   
           BitmapFactory.Options options = new BitmapFactory.Options();
           options.inJustDecodeBounds = true;
           BitmapFactory.decodeFile(picturePath, options);
           int imageHeight = options.outHeight;
           int imageWidth = options.outWidth;
           String imageType = options.outMimeType;
               options.inSampleSize = calculateInSampleSize(options,200,100);//512 and 256 whatever you want as scale
               options.inJustDecodeBounds = false;
           Bitmap yourSelectedImage = BitmapFactory.decodeFile(picturePath,options);
   
           File pngDir = new   File(Environment.getExternalStorageDirectory(),"PicUploadTemp");
           if (!pngDir.exists()) {
               pngDir.mkdirs();
               }
   
         File pngfile = new File(pngDir,"texture1.jpg");
           FileOutputStream fOut;
   
           try {
                   fOut = new FileOutputStream(pngfile);
   
                    yourSelectedImage.compress(Bitmap.CompressFormat.JPEG, 50,fOut);
   
   
           } catch (FileNotFoundException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
           }
           Drawable d = Drawable.createFromPath(pngfile.getPath().toString());
           rlLayout.setBackground(d);
   
           yourSelectedImage.recycle();
       //    resizedBitmap.recycle();
   
           xfile = pngfile; 
       }
       break;
   

cam.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    Intent cameraIntent = new Intent(
                            android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                    startActivityForResult(cameraIntent, CAMERA_REQUEST);
                }
            });
