android为什么我无法检索压缩位图？

Question

这是我做的事情

FileOutputStream out = new FileOutputStream(
                        "/sdcard/Deltio1.jpg");
                Bitmap e = BitmapFactory.decodeByteArray(imageData, 0,
                        imageData.length);
                e.compress(Bitmap.CompressFormat.JPEG, 65, out);
                out.close();

并检索它

FileInputStream fin = new FileInputStream("/sdcard/Deltio1.jpg");
            ObjectInputStream in = new ObjectInputStream(fin);
            Bitmap bitmap;
              bitmap = (Bitmap) in.readObject();
              ImageView photo = (ImageView) findViewById(R.id.katagelia_photo);
              photo.setImageBitmap(bitmap);

抛出java.io.StreamCorruptedException

Answer 1

找到它。但是我把它留待讨论，为什么第一个失败了。

 Bitmap bm = BitmapFactory.decodeFile(myJpgPath, options); 
 options.inSampleSize = 2;
