"creating unsigned app" message in console while building for Play store beta

jeff63 · May 1, 2018, 7:48pm

Hi,

The console included the following message: “creating unsigned app” while building the newest version of my app for the Play store.

I’m using the same keystore that I created and used for the first build I ran for a store release. I don’t recall seeing that “creating unsigned app” message during that build.

Is my apk file in fact not signed or am I misunderstanding that message, and/or what it means to be signed? Google accepted the new file when I uploaded it (uploading as beta releases).

Are you using the debug keystore or are you using a hand created keystore?

I’m using the one I created following the tutorial

https://coronalabs.com/blog/2014/08/26/tutorial-understanding-android-app-signing/

I tried using jarsigner to see how it was signed (replacing your_apk.apk with the actual file name) :

jarsigner -verify -verbose -certs your_apk.apk

But Terminal returned an unable to unzip error

found info about jarsigner here:

Is this message showing up in your Corona simulator’s console log window during build? Can you copy/paste the entire log file? Can you provide a screen shot of your build dialog just before you click the “Build” button? Please do not blur out/redact any fields.

Thanks for the help, Rob.

Yes, it’s showing up in the simulator’s console log.

I’ve just built it twice and noticed the log file from the second time doesn’t contain as much info as the first, but they both contain the creating unsigned message

here’s the log from the first time

I believe this is a message that’s not important. When we build on the server, we don’t sign the app there. Signing happens once we send the build back to your computer. Unless you’re seeing a problem other than a message in the build log, I think your fine.
