Is it possible to watch variables at runtime?

I know the basics of debugging, and I know I can add watches to a variable that stop the program's execution on a given condition. But I didn't want to stop the program every time I need to see the value of a variable. Neither I want to log the value of every relevant variable into logcat... I only wanted to see their values like I do at breakpoints, only in runtime.

I'm programming Android, in Android Studio.

Thanks for the help!
