AndroidでDefaultHttpClientを使用してWebからファイルをダウンロードする方法を知っている人はいますか?
可能なオプションのほとんどを試しました。openurl接続ですが、DefaultHttpClientを使用する必要があります。

前もって感謝します

一例を挙げると、これは間違いなくHttpClient httpclient = new DefaultHttpClient();に役立ちます。

 // Prepare a request object
 HttpGet httpget = new HttpGet("http://www.apache.org/");

 // Execute the request
 HttpResponse response = httpclient.execute(httpget);

 // Examine the response status
 System.out.println(response.getStatusLine());

 // Get hold of the response entity
 HttpEntity entity = response.getEntity();

 // If the response does not enclose an entity, there is no need
 // to worry about connection release
 if (entity != null) {
     InputStream instream = entity.getContent();
     try {

         BufferedReader reader = new BufferedReader(
                 new InputStreamReader(instream));
         // do something useful with the response
         System.out.println(reader.readLine());

     } catch (IOException ex) {

         // In case of an IOException the connection will be released
         // back to the connection manager automatically
         throw ex;

     } catch (RuntimeException ex) {

         // In case of an unexpected exception you may want to abort
         // the HTTP request in order to shut down the underlying
         // connection and release it back to the connection manager.
         httpget.abort();
         throw ex;

     } finally {

         // Closing the input stream will trigger connection release
         instream.close();

     }

     // When HttpClient instance is no longer needed,
     // shut down the connection manager to ensure
     // immediate deallocation of all system resources
     httpclient.getConnectionManager().shutdown();
 }
