UE4.25 Android packaging error

[Εxtrone]

I decided to port my project to 4.25 from 4.24. I set up Android Studio and all that. But I'm getting this error when trying to package for Android(ETC2).
I see that it's says some java modules are missing, but how do I fix this?

Looks like the problem was with a plugin I used. Removed the plugin. Now the Build is successful.

Hello,

which plugin it was exactly? I have the same error and dont know how to fix it. Can you give me some suggestion?

Thank you

[vrcadeandchill]

Any word on this? I'm also having a similar issue and can't figure it out.

Hi, anyone got a solution for this? Happens for me on 4.25 also.

[Lord7even]

Same problem here. What causes this? 4.25 seams to be so full of bugs when it comes to packing for android.....

[Joost]

Has anyone managed to fix this problem? I'm on the latest version of the Oculus engine build.

In my case it was a "websocket" plugin I got from Github. The project has since been deleted. It had a UPL file which copied some files and enabled AndroidX (android.useAndroidX=true & android.enableJetifier=true) I commented out everything in that file and I managed to package successfully. But now the game crashes on launch, not sure if it's related to the plugin.

There will be some problem with SDK installation, go to the android folder in unreal installation and run setup.bat as admin. then use that path for SDK.
