After compilation, two applications appear on the desktop, how to remove the second one?

Question

Java

After compiling the project in Android Studio, two applications appear. At the same time, they have the same package name, but one application opens a normal application, and the other an empty variant.

Answer 1

Most likely, you have different versions of the application and different keys for them. In this case, the android considers that these are different applications, despite the name being the same.
