这是我最近实施的，它是产生这个错误在我的Andr​​oid应用程序的code是：

The code that I have recently implemented that it is generating this error for in my Android app is:

        FileOutputStream fOut = null;
        try {
            fOut = this.openFileOutput("employeeInformation.xml", MODE_PRIVATE);
            try {
                InputStream is = new URL("http://totheriver.com/learn/xml/code/employees.xml").openStream();
                int size = is.available();
                byte[] buffer = new byte[size];
                is.read(buffer);
                is.close();
                fOut.write(buffer);
             } catch(Exception e) {
                 e.printStackTrace();
             }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            try {
                fOut.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

有谁知道问题是什么？

Does anyone know what the problem is?

推荐答案

添加Internet权限到你的清单：

Add Internet permission to your manifest:

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