I want to rename my published app during next upgrade, will the Android Market treat this as just another regular upgrade and preserve the associated ratings and comments? The app will keep the same package name.
As long as the package name is same , it doesn't matter what app name you keep. I frequently switch my apps Title(in market) and also app_name . and everything remains the same
