Hi, do you work with the same project or another one?

[Denise]

Hi, all that happened was I created the app a few months ago but I made the target android 2.3.3-2.3.4 and now it isn't compatable with the latest phones, so I went in and changed the target SDK version to 4.2x that is the only change I have made. I then exported the android apk, zipaligned it and got the above message from Google play??

Warm regards
Denise

Oh, I see now... sorry:) I'll update.

Sorry, could you clarify did you export app using Eclipse or through Appery.io builder?

[Denise]

Through tiggzi before it was appery.io

Please check if you have "Release" option ticked on App Settings--Android binary.

No it isn't should it be?
