How do I fix "Could not connect to remote process" while trying to debug the application?

I am making a android studio project and I try to debug my application.

Running the application works fine, but when I try to debug it I get this error:

Could not connect to remote process. Aborting debug session.

What can I do to fix the issue?

You need to restart the ADB.

kill adb.exe process.

how to restart ADB manually from Android Studio

Sometimes this happens when two Android-capable IDEs are opened, e.g. Android Studio and IDEA. Shutdown one of the two (or disable Android plugin in IDEA) helps.
