android - Updating download progress bar into notification area from AsynTask -

-

i have implemented async task service. here initializing of progress notification, calling onpreexecute.

mprogressnotificationmanager = (notificationmanager)             .getsystemservice(context.notification_service);      charsequence tickertext = "download";      mprogressnotification = new notification(r.drawable.ic_launcher, tickertext, system.currenttimemillis());     context = this.getapplicationcontext();      intent mnotificationintent = new intent(context, activityclass.class);     pendingintent mpendingintent = pendingintent.getactivity(context, 0, mnotificationintent, 0);     //mprogressnotification.flags |= notification.flag_auto_cancel;     mprogressnotification.flags = mprogressnotification.flags | notification.flag_ongoing_event;     charsequence title = "downloading initializing...";     remoteviews contentview = new remoteviews(getpackagename(),             r.layout.noti);     contentview.setimageviewresource(r.id.status_icon,             r.drawable.ic_launcher);     contentview.settextviewtext(r.id.status_text, title);     contentview.setprogressbar(r.id.status_progress, 100, 0, false);     mprogressnotification.contentview = contentview;     mprogressnotification.contentintent = mpendingintent;     mprogressnotificationmanager.notify(status_bar_notification, mprogressnotification);

after in doinbackground , have implemented download procedure, , after updating download progress,

@override     protected void onprogressupdate(integer... progress) {         super.onprogressupdate(progress);          int mdownloadprogress = progress[0];         // log.d(tag,"asynctask : download in progress");                    charsequence title =  "filename" +":  "  + mdownloadprogress + "%";         mprogressnotification.contentview.settextviewtext(r.id.status_text, title);         mprogressnotification.contentview.setprogressbar(r.id.status_progress, 100,                 mdownloadprogress, false);         mprogressnotificationmanager.notify(status_bar_notification, mprogressnotification);                  }

it working fine.. updating properly, issue that, notification bar hanged. can not up-down notification bar. want update notification bar downloading application google market (play) .

thanks...

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
