    same problem - just depends on size of used resources
    seems that uncompressed apk does not fit 2gb - that fail

    occasionally can hang in java

    I deleted any and all .webm video files from my project and now it builds out just fine.

    I hope this helps someone else!

    I am having the same issue. The odd part is, it was building fine in the person licensed version. I only started having this issue when I switched to Unity Plus....

    Upgrade and then it doesn't work? Maybe I should get a refund and go back to the free version?

    Fixed! In my case, having Ads Service ON and also having the Ads Assets in my project folder was causing the error. I removed all Ads Assets from my folder and everything's working fine.

    Having the same issue with Unity 2017.3.1f1.

    Will build if I don't add a 500meg video to be played, gives this error when I do.
    Makes it impossible to build out 360 panno app.
