ERROR: Build Failed: Error code: 256

Just before a few minutes, I couldn’t create an APK, are this problem corona side issue?

@bk_31,

I just did an “android build” with my simulator five minutes ago, with a simple “hello world” app, no plugin and no require. It runs okay. I am running Solar2D 2020.3600 on Windows.

What version of Corona or Solar2D are you using? Are you doing a simulator build or otherwise? You can find the various releases here,
https://github.com/coronalabs/corona/releases/

When I enable the OneSignal plugin I got the same error.

I’m using 3609 version, corona simulator.

First of all, can you confirm that you are you using JDK 8 and NOT the latest version? If you are using JDK 8 and this error continues, can you share your build.settings with us?
