I don’t know if this is causing the problem or not (doubt it), but you do realise that you specify the facebook plugin twice in the build.settings file you pasted above, right?
It’s possible that your project could have a file or folder in it that’s breaking things. For instance, if you’re on a Mac and you color your folder icon, or add an image to it, you get a file called Icon~23 (the ~23 meaning non-ASCII characters) and this will generate a failure to sign the app. Having a “res” folder will cause this as well. Can you perhaps post a directory listing of the folder with your main.lua in it?

Thanks Rob, that was exactly the case. I had a folder that was not required that was new to this project, it did not upset the IOS build, but removing fixed the cert error on Android. 
I’m glad that was it. Certificate problems are the most frustrating to solve because there is no code to post to look at. All we can do is guess at what’s going on.
I’m working on an app right now and I’ve spent the last half hour getting cert failures too. I had two issues tonight. First, I had switched to the debug keystore and when I switched back to the real keystore and it didn’t ask for my password. I had to do it again and finally got it to prompt me for my password. Then the version on my Nexus 7 was with the debug keystore and I was trying to write over it with adb install -r and it wouldn’t have anything to do with that, so I had to remove the debug version to put the production version on.
Rob
As a matter of interest, what was the name of the folder that caused the problem?
It was folder called “_Font Pack 1” from text candy x-pressive demos, (great prodcut) More likely one of the files inside.
Thanks for awesome support Corona.
Can you provide a list of the files in that folder?
Rob
A lot files, so I looked through for anything odd and non ascii, see below…

I’m not so interested in non-ASCII. Can you just do a directory listing and post them all?

Thanks. Perhaps engineering can spot a file name there causing problems.
