surfaceview - Android: Application lost the surface when recording to dynamic object -

-

i in bit of pickle. trying display camera feed while view launched background service. getting runtime error 

04-19 15:00:31.872 31125-31442/csce483.vbox e/recorder: starting prepare 04-19 15:00:31.872 31125-31442/csce483.vbox e/mediarecorderjni: application lost surface 04-19 15:00:31.872 31125-31442/csce483.vbox e/recorder: starting record 04-19 15:00:31.872 31125-31442/csce483.vbox e/mediarecorder: start called in invalid state: 4

when use dynamically created view. , static view not compatible window manager.
in oncreate():

try {     mcamera = camera.open(); } catch (exception e) {     e.printstacktrace();  }  msurfaceview = (surfaceview) view.inflate(getbasecontext(),r.layout.camera,null); //msurfaceview = (surfaceview) findviewbyid(r.id.surfaceview); mholder = msurfaceview.getholder(); mholder.addcallback(this); mholder.settype(surfaceholder.surface_type_push_buffers); msurfaceview.setvisibility(view.invisible);  yourbr = new myreceiver(); yourbr.setmainactivityhandler(this); intentfilter callinterceptorintentfilter = new intentfilter(); callinterceptorintentfilter.addaction("csce483.vbox.start"); callinterceptorintentfilter.addaction("csce483.vbox.stop"); registerreceiver(yourbr, callinterceptorintentfilter);

then in receiver:

public static class myreceiver extends broadcastreceiver {          mainactivity yourmain = null;          void setmainactivityhandler(mainactivity main){             yourmain = main;         }          @override         public void onreceive(context context, intent intent) {             string message = intent.getaction();             if(message.equalsignorecase("csce483.vbox.start")){                 if(!yourmain.recording) {                     log.e("accel", "received crash!");                     yourmain.msurfaceview.setvisibility(view.visible);                     yourmain.wm = (windowmanager) context.getsystemservice(window_service);                     windowmanager.layoutparams windowmanagerparams = new windowmanager.layoutparams(windowmanager.layoutparams.type_system_overlay);                     yourmain.wm.addview( yourmain.msurfaceview, windowmanagerparams);                     new thread(new runnable() {                         @override                         public void run() {                             yourmain.startrecording(); //record w/ new camera api                         }                     }).start();                 }             }             else if(message.equalsignorecase("csce483.vbox.stop")){                 log.e("accel", "recieved stop signal!");                 yourmain.stoprecording();              }         }     }

starting recorder:

    public void startrecording() {     //all file code temporary until server working     string timestamp = new simpledateformat("mmddyyyy_hhmmss").format(new date());     videofile = new file(environment.getexternalstoragedirectory(), "/pictures/"+timestamp+".mp4");     log.e("file", "saving to: " + videofile.getabsolutepath());      if (!videofile.exists()) {         file parent = videofile.getparentfile();         if (parent != null) {             try {                 videofile.createnewfile();             }             catch (ioexception e) {                 e.printstacktrace();             }         }     }      cameratriggered = true;      if(!camerapresent()) return;      if (mrecorder == null) {         mrecorder = new mediarecorder();     }      mcamera.unlock();     mrecorder.setcamera(mcamera);      mrecorder.setpreviewdisplay(mholder.getsurface());     mrecorder.setvideosource(mediarecorder.videosource.camera);     mrecorder.setoutputformat(mediarecorder.outputformat.mpeg_4);     mrecorder.setvideoencoder(mediarecorder.videoencoder.mpeg_4_sp);      mrecorder.setpreviewdisplay(mholder.getsurface());      if(this.getresources().getconfiguration().orientation != configuration.orientation_landscape) {         mrecorder.setorientationhint(90);     }     else {         mrecorder.setorientationhint(0);     }      mrecorder.setoutputfile(videofile.getabsolutepath());      try {         log.e("recorder","starting prepare");         mrecorder.prepare();     }     catch (exception e) {         e.printstacktrace();     }      try {         log.e("recorder","starting record");         mrecorder.start();     }     catch (exception e) {         e.printstacktrace();     } }

thanks!

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...
