How can I every 1 second command intentfilter on android? -

-

i want every 1 second registerreceiver.

i try 

registerreceiver(receiver, new intentfilter(intent.action_time_tick));

but code every 1 minute

i want every 1 second.

perhaps, android have form ?

thanks

what trying accomplish? if want have code executed every 1s, don't user broadcastreceiver. receivers result in inter-process communication every time triggered (relatively) expensive.

best way use handler,

private static final long tick_interval = timeunit.seconds.tomillis(1); private static final handler tickhandler = new handler(looper.getmainlooper());  public void onresume() {   super.onresume();   tick(tick_interval); }  private void tick(final long interval) {   tickhandler.postdelayed(     new runnable() {       public void run() {         tick(interval);         ontick();       }     },   ); }  protected void ontick() {   // }

ensure stop ticking when activity pauses,

public void onpause() {   super.onpause();   tickhandler.removecallbacksandmessages(null); }

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...
