调试代码的方法--将网络获取到的数据存储到文件中，然后打开文件看结果。

FileOutputStream fos = null;
try {
fos = myApplication.GetContext().openFileOutput("food.html", 0);
try {
fos.write(msg.getBytes());
fos.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
if (fos != null) {
try {
fos.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
