i writing tool simplify launching program needs run in command line. having problem windows 8 , xp need run command c:\program files (x86)\juniper networks\network connect\ncluancher.exe + ....now reason in windows 7 nclauncher found not in windows 8 keep getting error not locate c:\program. or invalid program arguments have been specified. 

string version_number = getprogramversion();         string url_location = "\"c:\\program files (x86)\\juniper networks\\network connect "             + version_number + "\\nclauncher" + "\"";         string[] location = {url_location + " -url " + url + " -u "             + user_name + " -p " + pass_word + "  -r s1ad"};         // location of network connect specified.         process pr = runtime.getruntime().exec(location);         bufferedreader input = new bufferedreader(new inputstreamreader(             pr.getinputstream()));

is there way make more universal xp,win 7 , 8 ? process builder work better trying do.

what found work using short hand command line method , mean typing c:\progra~2

identify os type , use different path each os.

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
