Android 4.4 KitKat random crash (Native crash at /system/lib/libc.so)

Question

I built an app that plays YouTube iframe video via WebView and controls video with YouTube iframe api.

(I know that YouTube SDK for Android may be more recommended for Android app development, but for now only iframe api fits our need)

I found out that the app randomly crashes when running under Android 4.4 KitKat.

This is the complete crash log from Google Play console:

And feedbacks from users are "It won't stop after I press stop button" and "It accidentally stopped".

Since this problem randomly happens, I cannot reproduce it and yet don't know how to fix it.

Any suggestion is highly appreciated! Thank you :)

Maybe you are trying to display a corrupted JPEG file. Try to open them all and see if there isn't one that fails to load.
