Error Publishing App to Gooogle Play

So it says package error :

Upload failed

You must use a different package name as "not.yet.specified" already exists in Google Play.

what should / must i do ?

This was just asked in another thread

Package name is already used in the market. Look out for "not.yet.specified" when you export your project in intel xdk / cacoon export settings and change it to something else that no one has used before.

Also in your project settings in C2, change it there too in case it is not.yet.specified

Where in Intel XDK i don't find it ??? THANK YOU!!

i can't i tried 1-2 hours and i didn't find anything pleas if you publish any app on google play please help me bro

"Projects" tab ->"Build Settings"

make sure you're doing the settings in the "android crosswalk" and not "android" tab.

You need to provide an APP ID to your project.

can be anything, as long as it has the format "com.something.something"

Thank You

PROBLEM SOLVED!
