NullPointerException when running release application

[abozanona]

When I run a release apk I get this exception after the VIdeoPlayer finishes downloading decoder.

java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.Object.hashCode()' on a null object reference
	at java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:944)

@abimujianto I didn't find a solution for this issue. I had to use flutter_ijkplayer instead.

[abimujianto]

Do you use androidx for your package flutter?

[abozanona]

Yes.

[abimujianto]

maybe gplayer not support on androidx ?

[abozanona]

I don't think that gplayer doesn't support on androidx. I tried to use gplayer before and after upgrading my project to androidx and the same error happened.

btw, i tried to release with android 9 its work, try downgrade your android version. its will work
