my APK is getting "Parse Error"

I get "Parse Error" - there is a problem parsing the package, when trying to run my APK. I successfully run the application on the emulator, package it using "Export signed.." from menu and using zipalign, everything looks correct. even the zipalign verification. I am using the latest PLUGIN on Eclipse 3.6 Helios, and tried to deploy to HTC Hero & Google Nexus S. Any idea what could be the pr开发者_运维问答oblem?

Using the export option from the Eclipse plugin will do the zipalign step for you automatically. Try generating it again, don't zipalign it manually and see what you get.
