i'm trying track down bug in software line. have 2 release build version 2.0.962 , 2.0.966. difference between these versions lib.so file. in order figure out start looking in source tree lib.so, need know version number in each of release builds. is there command line tool printing version of shared object? i never did native android programming android uses linux kernel, executable format used "elf". far elf concerned, there no version information of shared object stored in file. unless file name saying "libxxx.version.so" , there no other way find out version number of shared object. technique used in linux. my suggestions solving issue are: use date modified if possible differentiate shared objects use dlopen() or similar open shared object , try see functions being exported. source: http://man7.org/linux/man-pages/man5/elf.5.html note: e_version in executable version of elf format, not of executable.

i'm having trouble using createprocess command line arguments. i've read posts i've found none of solutions did work. here's have: std::string path = "c:\\my\\path\\myfile.exe"; std::wstring stemp = std::wstring(path.begin(), path.end()); lpcwstr path_lpcwstr = stemp.c_str(); std::string params = " param1 param2 param3"; startupinfo info = { sizeof(info) }; process_information processinfo; createprocess(path_lpcwstr, lptstr(params.c_str()), null, null, true, create_new_process_group, null, null, &info, &processinfo); the code works , myfile.exe (a qt application) opened, argc 1. i've tried specifying first parameter "c:\my\path\myfile.exe param1 param2 param3" didn't work either. any appreciated. solution: using createprocessa , change parameters accordingly fixed problem pointed out 1 of answers. startupinfoa info = { sizeof(info) }; process_information processinfo; std::string path = "c:\\my\\path\\

i need develop android library has service component. service requirements are: works started service (always started) started , restarted alarm service when required (another service within library) started system boot (boot_completed) provide way subscribe service events (which should executed in context of service, mean in background well) the purpose of service provide client (android application) use ability subscribe events should executed in background. dure limitation extended client should receive notification in background (even when client not started) can see extension service (derived service reconfigured @ manifest @ client app). what proper approach achieve goal? how should base service communicate client extension? so first client have add service androidmanifest.xml . client call methods library start service or alarm service, depending on needs. communication depends on data want send service client's app. if it's notification best wa

i couldn't find answers on how use/implement google content experiments gtm. i have set-up gtm container ga code , in original page experiment have google experiment code @ beginning of html tag. problem i'm having not users counted in google analytics experiments report. is still impossible use google content experiments in gtm? ( how run google experiment within google tag manager - seems bit old discussion) what best way of implementing experiment code in tag manager? it's still impossible implement google experiments gtm. however far understand - implemented experiment code in normal way. did checked if experiment set 100% of visitors? if it's less - it's normal visits outside of experiment , sounds case you. other - gtm shouldn't affect experiment in way, don't use gtm it.

from android documentation: public intent (context packagecontext, class<?> cls) parameters packagecontext context of application package implementing class. cls component class used intent. correct me if wrong: a context of application package implementing class. means package contains class want start. this shouldn't work(but works, why?), because this refers current activity, not application package says in documentation. a context of application package implementing class. means package contains class want start. here, "application package", cases, is referring app. this shouldn't work yes, should. this refers current activity, not application package says in documentation. assuming current activity , activity started both in same app, this works fine, "a context of application package implementing class". this not work if trying start activity other app, in case use implicit intent pattern, u

i have mutable bitmap , i'm drawing on canvas. after want draw pre-defined text on bitmap. problem have different bitmap sizes, though i'm setting text size 20sp, depending on bitmap size text bigger of smaller, want text size same images. should do? thought of maybe scaling text size depending on image width , weight i'm not sure how that. final bitmap mutablebitmap = bitmap.copy(bitmap.config.argb_8888, true); final canvas canvas = new canvas(mutablebitmap); final paint paint = new paint(); paint.settextsize(getresources().getdimensionpixelsize(r.dimen.myfontsize); canvas.drawtext(text, x, y, paint); first of if ondraw method doing wrong work here. shouldn't allocate inside ondraw method. on other hand , shouldn't change text size bitmaps. resize bitmaps on same values(width , height) , setting text same value.

since imageatomicadd (which seems real atomic "read-modify-store" function operates on images) available 32bit integers, don't see sensible way accumulate multiple color values different shader invocations in 1 pixel. the reasonable way can see use 32bit per color (128bit per rgba pixel), add 8bit color values up, hope doesn't overflow , clamp 8bit afterwards. seems wasteful , restrictive (only pure additive blending?) accumulating in other data structures doesn't solve issue, since shared variables , ssbos seem support atomicadd , on integers. there 2 reasons make me think missing something: 1. every pathtracer allows concurrent intersection testing (for example shadow rays) has solve issue seems there must solution. 2. kinds of fancy blending can done in fragment shaders, hardware capable of doing this. is writing pathtracers have 1:1 shader invocation:pixel mapping?
