Question

我是android的新手，并且在android中上传图片时出现问题。我已经试图找到例子，但没有运气：

我有错误说：

这是我的代码：我有名为"images"的数组，其中包含我要上传的图像路径例如/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));

我错过了什么吗？你能告诉我的代码有什么问题吗？
