android detect is gyroscope available -

-

how can detect whether android device has gyroscope? i'm using following method detect whether gyroscope available. if gyroscope not available, use accelerometer.

sensormanager mgr = (sensormanager) getsystemservice(sensor_service);         list<sensor> sensors = mgr.getsensorlist(sensor.type_all);         (sensor sensor : sensors) {             log.i("sensors",sensor.getname());            if(sensor.getname().contains("gyroscope")){                try{                 msensormanager.registerlistener(this,                            msensormanager.getdefaultsensor(sensor.type_rotation_vector),                            sensormanager.sensor_delay_fastest);                 return;                }catch(exception e){                }            }         }         msensormanager.registerlistener(this,                 msensormanager.getdefaultsensor(sensor.type_accelerometer),                 sensormanager.sensor_delay_fastest);

however of app users complaint can't use gyroscope. there problem code?

you can use package manager's system features check if device has gyroscope in it:

packagemanager packagemanager = getpackagemanager(); boolean gyroexists = packagemanager.hassystemfeature(packagemanager.feature_sensor_gyroscope);

your current code may not work on devices sensor name not guaranteed contain gyroscope in it.

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...
