读取网络文件并按行存储

容易忘记fos.close()，会导致存的文件为空白。。

 

try {URL url = new URL(urlToRssFeed);InputStream is = url.openStream();fos = openFileOutput("url.xml", Context.MODE_PRIVATE);BufferedReader br = new BufferedReader(new InputStreamReader(is));String line = br.readLine();int line_num=0;while(line!=null){line_num++;Log.i(getFeedTag, "["+line_num+"] "+line);line+="/n";fos.write(line.getBytes());line = br.readLine();}fos.close();FileInputStream fis = openFileInput(filename);return getFeed(fis);} catch (MalformedURLException e) {// TODO Auto-generated catch blockreturn null;} catch (IOException e) {// TODO Auto-generated catch blockreturn null;}
