change code of activity following. package de.vogella.android.downloadmanager;

import android.app.activity; import android.app.downloadmanager; import android.app.downloadmanager.query; import android.app.downloadmanager.request; import android.content.broadcastreceiver; import android.content.context; import android.content.intent; import android.content.intentfilter; import android.database.cursor; import android.net.uri; import android.os.bundle; import android.view.view; import android.widget.imageview;  public class downloadmanageractivity extends activity {     private long enqueue;     private downloadmanager dm;      /** called when activity first created. */     @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);          broadcastreceiver receiver = new broadcastreceiver() {             @override             public void onreceive(context context, intent intent) {                 string action = intent.getaction();                 if (downloadmanager.action_download_complete.equals(action)) {                     long downloadid = intent.getlongextra(                             downloadmanager.extra_download_id, 0);                     query query = new query();                     query.setfilterbyid(enqueue);                     cursor c = dm.query(query);                     if (c.movetofirst()) {                         int columnindex = c                                 .getcolumnindex(downloadmanager.column_status);                         if (downloadmanager.status_successful == c                                 .getint(columnindex)) {                              imageview view = (imageview) findviewbyid(r.id.imageview1);                             string uristring = c                                     .getstring(c                                             .getcolumnindex(downloadmanager.column_local_uri));                             view.setimageuri(uri.parse(uristring));                         }                     }                 }             }         };          registerreceiver(receiver, new intentfilter(                 downloadmanager.action_download_complete));     }      public void onclick(view view) {         dm = (downloadmanager) getsystemservice(download_service);         request request = new request(                 uri.parse("http://www.vogella.de/img/lars/larsvogelarticle7.png"));         enqueue = dm.enqueue(request);      }      public void showdownload(view view) {         intent = new intent();         i.setaction(downloadmanager.action_view_downloads);         startactivity(i);     } } 

also add permission go internet app.

if implemented example have android application can download picture (sorry ;-)) , allow switch download manager see finished downloads.

hope helps.
