1. DefaultHttpClient httpclient = new DefaultHttpClient();

2. HttpGet req = new HttpGet(url);

3. HttpResponse response = httpclient.execute(req);

4. HttpEntity resEntity = response.getEntity();

5. InputStream is = resEntity.getContent();

6. ...

由于篇幅关系，这里就不一一介绍了。文后将附上利用DownloadManager下载的代码与AndroidManifest.xml。
