Error on Build. Please Can someone help me.. its already been 2 weeks been posting here

Im packaging a simple third person blueprint on mobile… but i have errors on this past 2 weeks… so i created a blank and tried but still got errors.
Please help me with this…

I been posting all errors here on answershub but no one answers it… this was the last i encounter i really dont have an idea.

I can’t read the error message. compression artifacts are distorting the letters.

Here is the Error_Log of project launcher.

“Caused by: java.lang.ClassNotFoundException: sun.misc.BASE64Encoder”

You or epic is using the wrong class according to this stackoverflow awnser. If it’s not you than it’s a bug they can fix.

How can i submit this As Bug for the UE Support to check if its really a bug…
Cause i never use any plugin its just blank project and i tried to package on mobile. sorry im new on unreal but i checked all details and tutorials also documentations on android deployment.

i fixed the problem by downgrading to JDK 8 but another problem pops…
when the apk installed and launch it crashed upon opening always says “Unfortunately [app_name] stops.”
thanks for the two who commented and take time to check this with me. but there are another problem.

I’d follow these instruction.

Or

There’s a submission form here.
