question

It looks like your binary contains an invalid version name string within the manifest. The version string should only contain numbers and decimal points. No symbols should be used. Here are examples of accepted and non-accepted version strings: - Accepted: "1.22", "1.2.2", "2.334", "1.2.4.3" - Not accepted: "1a", "1.2beta", "1.2 New Update includes Chinese characters", "1.23 (great updates)" Please review the version name in your binary, make any changes required and upload it again via the Amazon Mobile App Distribution Portal. Here is a link to our blog post on the manifest requirements for your reference: http://www.amazonappstoredev.com/2011/04/preparing-the-androidmanifestxml-file.html

Yes, that's fixed it. Thank you! It might be an idea for you to put that information (or a link to it) on the page in question. Currently the error message is a bit inscrutable.
