Why is LogCat outputting a bunch of messages that aren't mine?

Question

Android

I created a new project and decided to test it through the device, but all messages from the device are displayed in the logs, and I can’t track my logs and errors.
Before that, everything was fine with the project, there were only logs from my application.
What can I do to display messages only from my application?

Answer 1

When the application is running on the device, select it from the LogCat list.

Answer 2

select your application for debugging (next to the device) + filter by tags
