android - How to force an IntentService to stop immediately with a cancel button from an Activity? -

-

i have intentservice started activity , able stop service activity "cancel" button in activity. "cancel" button pressed, want service stop executing lines of code.

i've found number of questions similar (i.e. here, here, here, here), no answers. activity.stopservice() , service.stopself() execute service.ondestroy() method let code in onhandleintent() finish way through before destroying service.

since there apparently no guaranteed way terminate service's thread immediately, recommended solution can find (here) have boolean member variable in service can switched in ondestroy() method, , have every line of code in onhandleintent() wrapped in own "if" clause looking @ variable. that's awful way write code.

does know of better way in intentservice?

stopping thread or process dirty thing. however, should fine if service stateless.

declare service separate process in manifest:

<service      android:process=":service"      ...

and when want stop execution, kill process:

activitymanager = (activitymanager) getsystemservice(activity_service); list<runningappprocessinfo> runningappprocesses = am.getrunningappprocesses();  iterator<runningappprocessinfo> iter = runningappprocesses.iterator();  while(iter.hasnext()){     runningappprocessinfo next = iter.next();      string pricessname = getpackagename() + ":service";      if(next.processname.equals(pricessname)){         process.killprocess(next.pid);         break;     } }

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...
