I'm trying to grasp what's actually happening still but the short of it is I have a WebView which tries to load a flash file (audio/video embed) then hangs for a moment before the entire app crashes to the home screen.
I do understand flash is no longer officially supported but to my knowledge for the moment Flash still sideloads fine even on other devices that are current.
After getting a hold of a person with an S4 and grabbing the adb log output I've come across something about Android that's over my head. It seems to say that Flash plugin is attempting to use /system/lib/libmedia.so and runs into an error that ends it completely. Our whole app goes with it however instead of ending up with a blank WebView.
The player embed is actually correctly loading on the S4 up until it tries to play. In the first trial no crash occurred and the video played fine but lacked any audio. Then relaunching the app for a second trial (and every time after) it would instead run into this error and crash the app entirely.
(Here's a condensed paste of the stack/log that I have. I'm trimming off a lot on the top that's just a few hundred lines of raw memory.)

The one line with android::AudioTrack::stopped() const+14 is what stands out to me but I'll tack on I'm not familiar with this kind of output for a bug. I searched around about libmedia.so and my understanding so far is that different roms might have different versions of this library and whatever flash uses it for has been changed in the S4. Could be audio or video I suppose but I did have a trail where video somehow worked fine in silence.
So is it that Samsung modified (and seemingly broke) a library of Android in their stock rom or am I greatly misunderstanding this? At the moment it looks like I can't do anything to fix our app but I don't even know, what does all this mean?
