java - 在 Parse.com 上保存图像

Question

我想将图像上传到 parse.com。我从图库中选择图像并将其放置在 Activity A 中的 ImageView 中，如下所示:

addImage.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                startActivityForResult(i, RESULT_LOAD_IMAGE);
}
};

然后，在 OnActivityforResult 中:

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
             mMediaUri = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(mMediaUri,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

           // ImageView imageView = (ImageView) findViewById(R.id.imgView);
            propertyImage.setImageBitmap(BitmapFactory.decodeFile(picturePath));

            Bitmap bmp = BitmapFactory.decodeFile(picturePath);
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byteArray = stream.toByteArray();

        }

然后我通过Intent发送字节数组:

intent.putExtra("Image",byteArray); 

现在进行 Activity B:

byte[] data = getIntent().getByteArrayExtra("Image");


        final ParseFile file = new ParseFile("propic.png", data);
        file.saveInBackground();

最后我将其发送给解析:

listedProperty.put("PropPic", file);

从那时起，数据就不再进入我的解析类，并且我从解析中得到不成功的回调。可能出了什么问题？

不确定这是否有帮助，但我保存位图图像以这样解析，这是用相机拍照后的。

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    byte[] image_byte_array;
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        post_object = new Post();
        Bundle extras = data.getExtras();
        image = (Bitmap) extras.get("data");
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        image.compress(Bitmap.CompressFormat.PNG, 100, stream);
        image_byte_array = stream.toByteArray();
        picture_file = new ParseFile("Picture", image_byte_array);
        picture_file.saveInBackground();
        post_object.put("Image", picture_file);
        post_object.saveInBackground();
    }
}
