I'm trying to get up to Google Play but I'm in trouble already follow all ta here: http://developer.android.com/tools/publishing/app-signing.html
But still will not. Speaks on Google Play:
Você enviou um APK não assinado. Crie um APK assinado
The terminal executing this command:
jarsigner -verify -verbose -certs android-debug-unaligned.apk
Message appears:
jar verified.
Warning: This jar contains entries whose certificate chain is not validated. This jar contains signatures that does not include a timestamp. Without a timestamp, users may not be able to validate this jar after the signer certificate's expiration date (2046-01-20) or after any future revocation date.
