android - whether the permanent value returned by these methods? -

activity.getpreferences(mode) , sharedpreferences.edit() can this?

(at activity class):

//... private sharedpreferences pref; private editor editor; oncreate() { pref = getpreferences(activity.mode_private); editor = pref.edit(); } ondestroy() { int somesavedint = pref.getint("someint", 0); editor.putint("someint", somesavedint * 2); } //...

or before utilize should value of pref , editor?

you can create static variable of shared preference too. or can each time, both fine.

just maintain in mind have editor.commit(); save/commit these values always.

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...
