"Problem parsing the package" error on install

I build a really simple game in Corona and uploaded it to Google drive … click to install it on the device for testing and I get a pop-up:

“Parse Error: There was a problem parsing the package”

I tried several times to make sure it wasn’t a parity error (yes, I looked to make sure it was really re-downloading the file).

Then I rebuilt the code, uploaded the new version to G-drive, downloaded, etc. … same error happened again (again, tried several times to download in case it was a parity error … same error each time).

Any ideas what’s going on?  Has anyone else seen these kinds of “parse errors” on the apk package?

Not sure if it is related, but I found this on the forums:

The error there was “INSTALL_PARSE_FAILED_CERTIFICATE_ENCODING” – not exactly what I’m seeing – and was related to Java versions. 

But since I’m on the starter plan, I’m not sure how my local Java install could impact the build which is happening on Corona’s servers.  Does Corona do most of the build on their servers, but signs the app on my machine?  (there were comments about running jarsigner to correct the certificate error)

OMG … dumb dumb dumb … apparently you can’t have a number as the first character in the package name!

I changed 3panel to ThreePanel and it installs fine.   ugg.
