java - NoSuchMethodError Exception with SetLocale -

-

in xamarin, have created following extension change locale on fly:

public static void toenglishlocale(this activity activity) {     locale locale = new locale("en-us");     configuration config = new configuration();     config.setlocale(locale);     activity.basecontext.resources.updateconfiguration(config, activity.basecontext.resources.displaymetrics); }

i targeting api 15 , fails following exception on api 15:

unhandled exception:  java.lang.nosuchmethoderror: no method name='setlocale' signature='(ljava/util/locale;)v' in class landroid/content/res/configuration;

is there other "unified" way change locale on fly? thanks!

the method setlocale added in api level 17 that's why getting error.

you can use android.os.build.version.sdkint property find api version @ runtime , call method if android.os.build.version_codes.jellybeanmr1 or newer. if isn't should set locale public property instead of calling setlocale

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
