android - How to use MediaSessianCompat for Media playback? -


i have spent literally whole day trying understand how mediasessioncompat works , does? how different mediaplayer or audiomanager class? honest did not find explanation. info got android docs , codes found on web which, according me not sufficient in case. helpful thing this video ian lake found on youtube. still not able understand how can use in our app.

this code found ian lake, , spent quite time on still have lots of doubts.

package com.example.remotecontrolclient;  import android.app.service; import android.content.componentname; import android.content.context; import android.content.intent; import android.graphics.bitmapfactory; import android.media.audiomanager; import android.os.ibinder; import android.support.v4.media.mediametadatacompat; import android.support.v4.media.session.mediasessioncompat; import android.support.v4.media.session.playbackstatecompat;  public class playerservice extends service {     private mediasessioncompat mediasession;      @override     public void oncreate() {         super.oncreate();         componentname receiver = new componentname(getpackagename(), remotereceiver.class.getname());         mediasession = new mediasessioncompat(this, "playerservice", receiver, null);         mediasession.setflags(mediasessioncompat.flag_handles_media_buttons |                 mediasessioncompat.flag_handles_transport_controls);         mediasession.setplaybackstate(new playbackstatecompat.builder()                 .setstate(playbackstatecompat.state_paused, 0, 0)                 .setactions(playbackstatecompat.action_play_pause)                 .build());         mediasession.setmetadata(new mediametadatacompat.builder()                 .putstring(mediametadatacompat.metadata_key_artist, "test artist")                 .putstring(mediametadatacompat.metadata_key_album, "test album")                 .putstring(mediametadatacompat.metadata_key_title, "test track name")                 .putlong(mediametadatacompat.metadata_key_duration, 10000)                 .putbitmap(mediametadatacompat.metadata_key_album_art,                     bitmapfactory.decoderesource(getresources(), r.mipmap.ic_launcher))                 .build());          audiomanager audiomanager = (audiomanager) getsystemservice(context.audio_service);         audiomanager.requestaudiofocus(new audiomanager.onaudiofocuschangelistener() {             @override             public void onaudiofocuschange(int focuschange) {                 // ignore             }         }, audiomanager.stream_music, audiomanager.audiofocus_gain);         mediasession.setactive(true);     }      @override     public int onstartcommand(intent intent, int flags, int startid) {         if (mediasession.getcontroller().getplaybackstate().getstate() == playbackstatecompat.state_playing) {             mediasession.setplaybackstate(new playbackstatecompat.builder()                     .setstate(playbackstatecompat.state_paused, 0, 0.0f)                     .setactions(playbackstatecompat.action_play_pause).build());         } else {             mediasession.setplaybackstate(new playbackstatecompat.builder()                     .setstate(playbackstatecompat.state_playing, 0, 1.0f)                     .setactions(playbackstatecompat.action_play_pause).build());         }         return super.onstartcommand(intent, flags, startid);     }      @override     public ibinder onbind(intent intent) {         return null;     }      @override     public void ondestroy() {         super.ondestroy();         mediasession.release();     } }

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
