Android 图像压缩不工作

我正在尝试使用相机上传图片。我正在把它上传到服务器上

单击图像并在imageview中显示（完成）

压缩要上载的图像大小（不工作）

将图像上载到S3（带有未压缩图像）（完成）

这是我的onActivityResult（）

复制logcat并粘贴到这里（编辑您的答案）也许这个链接可以帮助您：“压缩图像大小以上传”？？？你想做什么？压缩或调整大小？@greenapps我想捕获一张图像，并在压缩后上传。压缩.jpg文件没有意义，因为它已经压缩好了。

        String picturePath = cursor.getString(columnIndex);
        cursor.close();

        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(picturePath, options);

        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);

            pngDir.mkdirs();

        FileOutputStream fOut;

        try {
                fOut = new FileOutputStream(pngfile);

                 yourSelectedImage.compress(Bitmap.CompressFormat.JPEG, 50,fOut);


        } catch (FileNotFoundException e) {

        }

        yourSelectedImage.recycle();

        xfile = pngfile;
