i'm developing android application has activity. activity has viewpager loads 2 fragments using fragmentstatepageradapter. this adapter being recreated on activity's onresume method. this how bug appears: with activity created, put app in background(using device's home button)and open other applications (specially consume lot of memory). after that, open again application background. have method in 1 of fragments in viewpager: public void dosomething(){ if(getactivity() != null) { ((homeactivity) getactivity()).dothings(): } } while debugging found getactivity() method returns null @ point. "dothings()" method never executed. noticed fragment's views created. i don't have problem when don't open other apps consume memory on app's background time. is overflow memory error? why getactivity() method returns null if fragment appears correctly loaded? thank in advance you can override onattach(activity) meth

i have problem. need analyze these 2 languages along sonarqube 5.6, idea how of it? i have install maven , msbuild sonarrunner never made them run together i don't understand how managed combine opposing tech stack in project. i guess talking 2 projects analysis in same sonar instance. in case use sonar.language=java enforce analysis of 1 language. if talking 1 project using 2 stack can work together, don't specify sonar.language sonar analyser deduct language analyse based on plugins have installed. if 1 project analysis done seperately override key , name of project distinguish them. can override passing command line arguments -dsonar.projectkey=asdf-java

i using octave 4.2 , using xlsread in loop import data several different rtds. importing using following code: for i=rtdmin:rtdmax filnum=num2str(i); fid = strcat(pre, filnum, filtyp); j = exist(fid); if j == 2 [num{i}, txt{i}, raw{i}, lim{i}] = xlsread(fid); time{i} = num{i}(:,2); temp{i} = num{i}(:,3); endif endfor the problem none of rtds have exact same number of readings (30,000 +-200), or stop , start @ exact same time, although readings overlap. because of variable size of data in each cell cannot pull out matrix in order process data. can suggest solution of how data matrix, or can suggest change existing code data read matrix begin with. thank in advance.

for our web api project use following url versioning system: https://{fqdn}/{apiversion}/{apiresourcename}/{resourcepath}?{parameters} for instance can have following: https://myapi.mysite.com/v1/customer/2 now considering above, let want release 2 versions (live,test) customer. 1 live version (working live data) , other 1 test (working test data customer development test). for live 1 use 1 mentioned : https://myapi.mysite.com/v1/customer/2 . how name test version of above api? test version of api url version v1? can specify test api url? also best practices qualified domain name of api {fqdn} when using url versioning? there several ways this. one way, instance, use attribute routing give different path. create separate method, give path of /vtest/customer/2 example , if users access /vtest/ version (or v2 or 3 or whatever) return test data/new version. see example in question another way host "test data" api in different application in ser

when try use: temp = new createjs.bitmap(obj.path) i error: uncaught error has occurred. due security restrictions on reading canvas pixel data local or cross-domain images. this related this question . except in above case user isn't using web-server. in case i'm using web-server need images hosted on aws s3 bucket using https. is there setting can use allow cors easeljs? cors settings on s3 bucket: <corsconfiguration> <corsrule> <allowedorigin>*</allowedorigin> <allowedmethod>get</allowedmethod> <maxageseconds>3000</maxageseconds> <allowedheader>authorization</allowedheader> </corsrule> </corsconfiguration> edit: related question bitmap not handle cors, since must define cross-origin property on image directly before setting src. the best way create image yourself, , apply cross-origin, before passing bitmap. var image = document

does following style of declaration in typescript files? /* globals console define require react async */ or there different way typescript? no has no effect on typescript compiler. what globals in scope typically selected choosing 1 of predefined library settings in typescript compiler options, example command line tsc --lib es5,dom brings global scope declared in files lib.es5.d.ts , lib.dom.d.ts supplied compiler. if lib.dom.d.ts can see how example window declared there: declare var window: window; window interface defined earlier in file. you can same own global variables - can create own .d.ts file containing declare var @ top level, , include file in compilation either on command line or adding files in tsconfig.json . everything installed in node_modules/@types included in compilation default, every global declared these typings in scope, unless limit setting "typeroots" or "types" in tsconfid.json . also, if use

i have been getting more functional approach writing javascript. i'm trying figure out how debugging should done in way when transforming arrays. more precise, how can use of breakpoints? here example a : myarray .filter(foofilter) .sort(foosort) .map(foomap) .reduce(fooreduce) how 1 add breakpoint this? if code looked instead (more imperative way) example b : const filteredarray = myarray.filter(foofilter); const sortedarray = filteredarray.sort(foosort); const mappedarray = sortedarray.map(foomap); const reducedarray = mappedarray.reduce(fooreduce); adding breakpoints example above not problem. so trying ask if possible somehow modify example a somehow support easier breakpoints? also, how should 1 think when comes debugging when writing according functional paradigm? edit 1: i trying put breakpoint through webbrowser such chrome. adding through changing code not solution im looking here. i trying add breakpoint after each transform see result of tra

i call function after x seconds , after y seconds etc.. number of seconds wait before calling function stored in qtime i thought launching timer , when value of qtimer has value of 1 of qtime, call function, dont' know @ how .. here idea in "pseudo-code" : qtime time1(0, 0, 10); // 00:00:10 qtime time2(0, 0, 15); // 00:00:15 // init qtimer if (qtimer.value == time1.value) function1(); if (qtimer.value == time2.value) function2(); how can ? thanks help the easiest way use 2 qtimer objects, each interval respective function. another option single timer fires @ rate of lowest common denominator, in case 5 seconds, , call each function @ appropriate count. i.e. function1 every second timeout, function2 every third timeout. another option calculate time until next event , start timer interval.
