Dale Beermann created CB-11390:
----------------------------------
Summary: Released Media are not removed from Android's
pausedForFocus or pausedForPhone lists, generating NullPointerException and
crash.
Key: CB-11390
URL: https://issues.apache.org/jira/browse/CB-11390
Project: Apache Cordova
Issue Type: Bug
Affects Versions: 6.1.1
Environment: Mac OS X 10.11.5, Cordova 6.1.1, Cordova android 5.1.1,
Nexus 5X running Android 6.0.1
Reporter: Dale Beermann
When changing views, the {{AudioHandler}} receives {{onAudioFocusChange}} and
adds all running media to a {{pausedForFocus}} list. With Angular, a
controller's life cycle might not exactly match what Android is seeing for this
event (I'm a bit unclear on how the focus change events are fired). So if that
media object is later released, it needs to be removed from those lists in
{{AudioHandler.release}}:
{quote}
pausedForFocus.remove(audio);
pausedForPhone.remove(audio);
{quote}
If this does not happen, the {{AudioHandler}} receives another
{{onAudioFocusChange}} event and calls {{resumeAllGainedFocus}} which calls
{{AudioPlayer.startPlaying}} with a {{null}} file, in turn calling
{{readyPlayer(null)}}, causing a NullPointerException and crash at the line:
{{if (this.audioFile.compareTo(file) == 0)}}
There might be a root cause here that I am missing, but this displays the
symptom I am seeing.
