Building a signed APK using C3 export manager doesn't work

Hi everyone,

All is in the title. I followed this tutorial ( construct.net/en/tutorials/building-a-signed-apk-for-android-in-construct-3-28 ) to create a signed APK, but I just get an "Build Failed / error" message from the export manager.

I don't see where I could have done something wrong. The only unclear point to me is that the Key Name should be what I've put in "Alias" when creating the keystore.jks file, right? If so, I believe everything should be correct.

Any idea of what could be the problem?

Following up, I've been able to create a signed APK.

I did a few tests and it seems like the ID, Author, website, etc of the C2 project was somehow causing the problem, even though everything was filled. I've modified some of the fields and now it works. :)
