android - A Local Service implementation closely related to Application Life Cycle -

in app. have extended application class myapp, , have few activities a,b,c,d default activity or root activity. want start service (say myservice) within oncreate of myapp , stop when user logs out application,

however need strong way communicate between activities (a,b,c,d), myapp , myservice. application launched sec time memory. oncreate of myapp not called start service onclick of signin button within activity a. have number of questions :-

i have tried both startservice , bindservice problem startservice don't service reference future use. if utilize bindservice create service visible through out application life cycle till explicitly stop it. way applicable in case ?

what best way implement communication between service , myapp / activities , vice verse ? communication mean 2 type of communication, 1. needs ui thread i.e. start activity, show dialog etc. 2. myservice.dosomehing().

the service has thread network communication should not closed during life time of application. start_sticky work me or need create arrangements that.

this app supposed run gingerbread+ devices...

bind service within extended app oncreate , create public method (getbinding) returns binding object ... in root/default activity 'a' oncreate via getbinding method on casted getapplication object retrieve .. unbind when activities close (keep counter each getbinding method)

check cleanly binding/unbinding service in application

so 1) bind service 2) binding obj 3) start sticky enough

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
