Question

通过使用Web服务，我们可以将文件从云下载到缓冲存储。我们现在需要从缓冲存储器访问这个下载的文件并将其移动到SD卡。我正在使用Eclipse和Android插件。

有人可以共享任何代码吗？

我的代码段在下方。

      String filename = "Test.zip";
      URL url = new URL(FromUrl);
      HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();  
      urlConnection.setRequestMethod("GET");
      urlConnection.setDoOutput(true);
      urlConnection.connect();  

      FileOutputStream fileOutput = openFileOutput(filename, Context.MODE_WORLD_READABLE);

      InputStream inputStream = urlConnection.getInputStream();  

      int totalSize = urlConnection.getContentLength();  
      int downloadedSize = 0;  

      //create a buffer...  
      byte[] buffer = new byte[1024];  
      int bufferLength = 0; //used to store a temporary size of the buffer  

      //now, read through the input buffer and write the contents to the file  
      while ( (bufferLength = inputStream.read(buffer)) > 0 ) {  
          fileOutput.write(buffer, 0, bufferLength);  
          downloadedSize += bufferLength;  
      }  
      //close the output stream when done  
      fileOutput.close();

      return filename;

只需保存到SD卡？

fileoutput = new FileOutputStream("/sdcard/"+filename);

这很快又脏，但是到目前为止找到的每个机器人都可以使用。如果你想要有点整洁......

File ofile = new File(Environment.getExternalStoragePublicDirectory (Environment.DIRECTORY_DOWNLOADS),filename);
FileOutputStream f = new FileOutputStream(ofile);

如何在android模拟器上下载文件？
