Minecraft 1.21 need java 21 and can't start with diffrent version if i remeber correct idk if mindustry want specific java version too

Iirc mindustry doesn't need java to run, since it's a compiled .exe file and not a .jar

Iirc mindustry doesn't need java to run, since it's a compiled .exe file and not a .jar

java doesnt compile to exe. the exe file is used to execute the desktop.jar (actual game) file in the jre/ directory;

using the java version installed in jre/bin and jre/lib sub directory.

but .exe file checks if java is installed if it is, uses the installed version in the os. if it is not, then it uses the one in jre/bin

if java version in the os isnt compatible, then it simply doesnt lunch

Would it be possible to see a receipt of which copy of Minecraft you bought in order to better assess how we can get your mindustry running? Your email should contain it.

Internally dying

downgrade it to 17 or 16.

minecraft doesn't install java automatically (into os), minecraft has a jre for every version in its data in %AppData%/Roaming/minecraft/runtime

unless the luncher needs it.

see if java 16 or java 17 works.

Does the .APK also contain the java VM? If not, how does it run it?

[mahdoosh1]

No, java VM is already installed in android phones. java is a cross platform language and most android apps are written in kotlin or java.

Android apps (.apk) are just zip files. in every apk file there are class files named classes.dex or classes2.dex

these are integrations of all compiled classes of the source code of the app. in this case Mindustry apk file has only classes.dex.

Thats the magic of java - its compiled to bytecode, which is run by the jvm. Only the jvm needs to be compiled separately for different devices, so everyone can run the same code. A .jar or .apk is just a zip file of .class files and other assets

were not supposed to explain java in the issue tracker.

and the author of this issue seems to be ignoring his issue and not playing mindustry anymore.

Anuke please close this issue.
