Problem When I upload app to Google Play

[Mohammed Shomis]

I have made an app by your site , but I edited the app and added some things by using apktool , and now I'm trying to upload it to Google PLay but it still getting me this error "You uploaded an APK that is signed with a restricted certificate. You need to upload an APK signed with your own certificate. "

Please , anyone can help please

You must have signed it with the Default Android Test Certificate!
If you are uploading for the 1st time, create a KeyStore with your credentials, sign it & upload...

Everytime you upload your app, sign it with the KeyStore you created!
