I try to update customers App in Google Play, this is my first time I do this.
I created a certificate, it seems to be fine. The app was packaged with appcelerator titanium.
When I upload the app in store I get this message:
The name ofupdated APK-Package (gdp.app) must be the same with the package I want to replace (de.gdp)
File Name I upload is: GdP.apk
What do I have to change?
You changed the package name. You have to use the same package name as the original .apk.
Change your package name back to de.gdp .
