audio - How to handle failed AudioFocus requests in Android? -


i working on application has media playing features.

i honor audiofocus. first request audifocus: 

audiomanager.requestaudiofocus(new customonaudiofocuschangelistener(), audiomanager.stream_music, audiomanager.audiofocus_gain);

this call returns either audiofocus_request_failed or audiofocus_request_granted. guess shouldn't start playback if receive audiofocus_request_failed. do?

will customonaudiofocuschangelistener notified when focus becomes available or when got autofocus_request_granted starts getting updates?

should inform user , ask him try again later? or retry programmatically after time?

thanks in advance

what depends on how want app react. shouldn't start playing, may want message user. or if non-critical, may silently ignore failure , move on.

i believe updates on listener on success. updates if you're lowered can choose duck output or pause until regain.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
