Github user ghenry22 commented on the issue:
https://github.com/apache/cordova-plugin-media/pull/122
So I have started to encounter the problem this fixes recently. Using
runkeeper along with my music app runkeeper will take the audio focus for it's
announcements. If it happens to do this just as your media is being released
or created then when it hands the focus back the app will fail as it will call
play on a media that wasn't successfully created.
Would be good to get this merged as it has resolved this issue for me on
Android with no side effects that I have noticed.
