Question

Solution: API 11 is needed see answer below!

Easy Question: After downloading a File with the implemented DownloadManager the Notification disappears. How do I force the Notification to stay after Download?

I tried to use VISIBILITY_VISIBLE_NOTIFY_COMPLETED, but i do not know how i can use it

Thank for any kind of help to solve this problem 😉

EDIT: Code

public class BgDL extends Activity {

private DownloadManager mgr = null;
private long id;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.main);

    mgr = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);

    Request request = new Request(Uri.parse(getIntent().getStringExtra("URL")));

    id = mgr.enqueue(request
            .setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "UPDATE")
            .setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI|DownloadManager.Request.NETWORK_MOBILE)
            .setAllowedOverRoaming(false)
            .setTitle("APP update")
            .setDescription("New version "+getIntent().getDoubleExtra("OV", 0.0))


    );

   registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

}
BroadcastReceiver receiver = new BroadcastReceiver () {


      public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals(mgr.ACTION_DOWNLOAD_COMPLETE) ){
            unregisterReceiver(receiver);
            finishActivity(99);
        }
      }


}; 

}

Add the correct flag to your request:

Request request = new Request(Uri.parse(getIntent().getStringExtra("URL")));

request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);

Reference:

http://developer.android.com/reference/android/app/DownloadManager.Request.html#setNotificationVisibility(int)

Control whether a system notification is posted by the download manager while this download is running or when it is completed. If enabled, the download manager posts notifications about downloads through the system NotificationManager. By default, a notification is shown only when the download is in progress.

http://developer.android.com/reference/android/app/DownloadManager.Request.html#VISIBILITY_VISIBLE_NOTIFY_COMPLETED

This download is visible and shows in the notifications while in progress and after completion.
