Hi,
Did you create the app using Android Studio?
Yes.
Has this app ran in the past?
No. I gave it a new name. First I created Hello and this was Hello2.
Have you searched the files that comprise your app (e.g., java, xml, gradle.build) for the "com.android.application" string?
No.
Actually I created another appliction "Hello3" and this time I did not get the message.
So I think problem has solved.
Thanks.
Zulfi.
