Intermittent crashes near the start / end of episodes, during MediaSessionCompat.setMetadata()

[orionlee]

Workaround (Sep 29 2016):
If your device is entry level or has little memory, try disabling lockscreen background in the settings. Disabling lockscreen background probably would alleviate most of the problems.

Problem Summary:

• When playing to near the end of episodes (or about to start the next one), Antennapod on my phone crashes intermittently but often enough (ballpark about 10% of time).
• logcat indicated indicated OutOfMemory error (need to allocate 7.5Mb), but I believed the device still enough of memory at that point (device had at least 30Mb free memory, though I understand it does not necessarily mean they are available to antennapod).
• The problem probably occurred around switching cover art OutOfMemoryError stacktrace shows it is triggered by Bitmap.nativeCopy() < ... ... < MediaSessionCompat.setMetadata() < antennapod...PlaybackService$$Lambda$2.run()
• It happened irrespective of whether phone screen is on: in other words, if the error was indeed triggered by switching covert art, the cover art was not needed nor in display at all (from end user perspective) as the screen was off.

Any help would be appreciated. Thanks!

First occured: a few weeks ago when I first used AntennaPod (1.6.1.2)

Environment: [Settings you have changed, e.g. Auto Download. "Unusual" devices you use, e.g. Bluetooth headphones. Do you still use Prestissimo?]

Quick fix: Turn off the lockscreen background

Images need huge amounts of memory and older phones often do not have that.

[orionlee]

@mfietz Thanks for the quick response. I was about to say I had lockscreen background disabled, but I double-checked it and found it was indeed enabled. I will try out to have lockscreen background disabled, and update later, to see if this is indeed the issue (and the workaround).

[orionlee]

@mfietz The workaround (disable lockscreen background) resolved most of the crashes. Thanks!

I still got (a few times) crashes with the Key id expected Long but value was a java.lang.Integer. The default value 0 was returned. error. If it persists (and recurring enough) I will log it separately.

[orionlee]

I logged the separate crashes with Key id expected Long but value as a java.lang.Integer error in #2134

[Bigpet]

@orionlee does Bigpet@7dd21c7 catch this without crashing ? Build an apk with it at https://www.petertissen.de/temp_files/app-play-release.apk if you don't want to build it yourself.
