"The app is not installed". What could be the problem?

Created a new app. Standard Hello World. I upload the file app-debug.apk to my phone. When installing, the message "The application is not installed"pops up.
1. The minimum version of the android device is the same.
2. This app wasn't on your phone before. Created, filled in the installation file, immediately an error.
If anyone has encountered this and solved the problem, please respond.

To generate the APK files correctly, select "build APK" in the "build" section. The resulting file can be used for installation on any device without debugging mode.
