android - At what point does my application code stop running when the device goes to sleep? -

-

specifically, if have method running in activity class, when phone goes sleep (cpu off), method run completion before onpause() called?

class myactivity extends activity {     ...     public void dosomework() {         ...         ... // <-- device goes sleep @ point in time         ...         return; // here before onpause() called?     }     ...     @override     public void onpause() {         ...     }     ... }

in addition activities, running thread (perhaps launched activity class) interrupted at whatever line of code it's at when device goes sleep? see contradicting answers in post: does thread launched activity continue running once device goes sleep?

going further, understand activity's onresume() invoked when device wakes up; if dosomework() above or aforementioned thread indeed interrupted midway when going sleep, remaining code resume?

thanks in advance insight.

it's considered android practice not run long tasks on main ui thread, therefore dosomework() supposed finish within few hundred milliseconds , reach return statement before onpause() called.

regarding dosomework() interrupted midway -- possibility of happen when application shows dreaded anr dialog , force closes, should not concerned restarting halfway through.

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

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...
