java - Why does my app keep crashing without any errors? -


so, trying implement qr scanner android application, , using android studio. user taps (clicks) button calls qr scanner onto screen. @ point, user can scan qr code embedded url , sent url. pretty simple.

i using [zbar][1] library. used awesome [tutorial][1].

i pretty followed tutorial outlined it, copying , pasting. had no compilation errors , application built without problems; however, upon running it, emulator throws me following message: "unfortunately, application has stopped."

if need anymore information please let me know.

here logcat outputs after crashes:

here oncreate function:

 @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     initcontrols(); }

you need load library yourself. can use following code in first activity want use scanner.

static {     system.loadlibrary( "iconv" ); }

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
