上传图片HTTP POST的Andr​​oid [英] Upload Image HTTP POST Android

问题描述

我在Android和有问题的android上传影像新手。我已经试图找到例子，但有没有运气：

我有错误说：

  

和这里是我的code：
我已经阵列名为图像它包含了我要上传图片的路径
例如/storage/sdcard0/DCIM/Camera/IMG_20131214_171438.jpg

I'm newbie in android and having problem uploading image in android. I'd already tried to find examples but got no luck:

I am having error saying:

and here is my code: I have Array named "images" which contains the paths of images that I want to upload e.g. /storage/sdcard0/DCIM/Camera/IMG_20131214_171438.jpg

//ONCLICK LISTENER    
public OnClickListener upload_image = new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                if(images.size() != 0) {

                    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
                    StrictMode.setThreadPolicy(policy);

                    for(int i=0; i<images.size(); i++){
                        doFileUpload(images.get(i));
                    }

            }

Did I missed somthing? Can you tell what is the problem on my code?
