android - DownloadMAnager Broadcast only DOWNLOAD_COMPLETE -


to improve comunication on different commponents want listen downloadmanager status. following reciever download_complete(success/failure) only,while alson need status pending, running, paused

public class downloadreceiver extends broadcastreceiver{      private context context;     private string tag = "downloadreceiver";      @override     public void onreceive(context context, intent intent){         log.i(tag, "onreceive");         this.context = context;         long downloadid = intent.getlongextra(downloadmanager.extra_download_id, -1);         log.i(tag, "downloader id: "+downloadid);          checkdownloadstatus(downloadid);     }       private void checkdownloadstatus(long id){         downloadmanager downloadmanager = (downloadmanager) context.getsystemservice(                                                                                         context.download_service         );         cursor cursor = context.getcontentresolver()                                .query(                                          downloadstateprovider.content_uri,                                          new string[]{downloadstatetable.column_id},                                          downloadstatetable.column_download_id + " =?
