Air App for Android - error 301: application descriptor missing

Greetings!

I've been building in Flash for a while but am brand new to mobile development.  I'm currently trying to create my first Android app, a very basic game called "302 Saves The Galaxy". I don't intend to sell the game.  I'm really just trying to learn my way through the publication process for future projects.

I've been able to get to the very last step in creating the apk file and I'm getting this error from the command-line process -

"Error 301: Application descriptor missing/cannot be opened"

Here's a screen shot of the command line window -

Here are a few other details about my process -

• In Flash, I selected to publish to Air 2.0 because that's the only option I had (ie, no Air 2.5 option)
• I've triple-checked and all spellings seem to be correct in my command-line syntax

I'm sure I'm missing something obvoius here.  Any suggestions?

Thanks in advance!

Joel
