Finding download complete from downloadManager in android

Question

I am downloading a file to the device external storage from my android app from a web server using DownloadManager. I need to initiate another function on completion of this download. my file download code goes like this:

String url = "http://192.168.1.105/download/file.ext";
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "files.ext");
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
final long downloadId = manager.enqueue(request);

please suggest how to get something like onDownloadComplete.....

can `downloadId` be used to know when download completes? – anant sophia May 08 '15 at 04:33 — anant sophia, May 08 '15 at 04:33

You can use ACTION_DOWNLOAD_COMPLETE with BroadcastReceiver

public class DonwloadCompleteReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // get complete download id
        long completeDownloadId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
        // to do here
    }
}

I believe there is some reported bug in it, see: http://code.google.com/p/android/issues/detail?id=18462 – anant sophia May 08 '15 at 06:05

I found my answer at : DownloadManager.ACTION_DOWNLOAD_COMPLETE broadcast receiver receiving same download id more than once with different download statuses in Android
and the code for me goes like this:

private boolean downloadComplete(long downloadId){
        DownloadManager dMgr = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
        Cursor c= dMgr.query(new DownloadManager.Query().setFilterById(downloadId));

        if(c.moveToFirst()){
            int status = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));

            if(status == DownloadManager.STATUS_SUCCESSFUL){
                return true; //Download completed, celebrate
            }else{
                int reason = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_REASON));
                Log.d(TAG, "Download not correct, status [" + status + "] reason [" + reason + "]");
                return false;
            }
        }
        return false;
    }

                 new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
