Packaging error: unknown cook failure

Hi. I made a small mobile game using blueprints and want to share it with some friends.
Runs fine in editor and can deploy to device, but packaging fails.
I have both codeworks and androidworks installed from previous engine versions.
Deleting Intermediate, saved and config files have not helped.
I can package any other project, just don’t understand code enough to figure this one out.
Thank you

Hello ,

I have a couple of questions to help narrow down the issue you are experiencing.

  1. Can you package other Android projects?
  2. Are you Android SDK files up to date?

Thanks!

Hi, thanks for replying.
Yes. i can package other android projects without problems.
I updated my graphics drivers and noticed that codeworks 1R6 has come out ( i remember installing 1R5). So i tried to install the new version, but that is giving me this error:
error MSB8020: The build tools for “arm-linux-androideabi-” (Platform Toolset = ‘“arm-linux-androideabi-”’) cannot be found. To build using the “arm-linux-androideabi-” build tools, please install “arm-linux-androideabi-” build tools.
do not understand how to fix it. can i just install vs2017?
Thank you

I am making a new project and remaking the game there. Thanks.
