通过ImageLoader下载图像

Question

我正在尝试使用ImageLoader获取下面的两个图像,我得到一个EACCES(权限被拒绝).我错过了什么？

在我的清单中我有:

<uses-permission android:name="android.permission.INTERNET" />

网址: http://projectcaruso.com/android/com.projectcaruso/idea/dumpfolder/345 http://projectcaruso.com/android/com.projectcaruso/idea/dumpfolder/342

我把它称为:

LocalImageLoader imageLoader=new LocalImageLoader(FeedActivity.this); imageLoader.DisplayImage(URL, image);

既然你收到了这条消息

 java.io.FileNotFoundException: /storage/emulated/0/LazyList/-649435551: open failed: EACCES (Permission denied)

你有没有？
