Android Package fail in 4.14.1 on Windows 10 "Unsupported major.minor version 52.0

[MuzzyA]

I followed this setup tutorial [Android Setup][1]

I originally had the issue after upgrading to 4.14 from 4.13 (I never tried it in 4.13 so I don’t know if it worked).

After throwing in the towel I decided to give it another shot.

1. I uninstalled UE4 and Epic Games Launcher

2. I uninstalled all of the NVPACK

3. Deleted all cache/references to those

4. Re-installed the Launcher and Unreal on my back up drive

5. Followed the Android Setup documentation again

6. Created a new Paper2D SideScroller project

7. Package Project->Android->Android (ETC 1)

8. Package fail with the the following issue

I should mention that the documentation shows the CodeWorks installation as CodeWorksforAndroid-1R4-windows

The version I see is CodeWorksforAndroid-1R5-windows

Hi,

Can you upgrade your java to 1.8, I see that you are still using 1.7. See if this works.

Thanks

[MuzzyA]

That worked! I spent hours upon hours on this thing. Thanks!

For those others that run into this issue you can download the 1.8 update Here
