How to Use the run tool in Tool windows

Question

My run tool of Tool windows in view is grayed out and I have no idea as to what to do to be able to use it

Answer 1

The Run Command is disabled when the Gradle is not built correctly.

Try Invalidating the cache.

Go to File > Invalidate Caches/Restart > Invalidate and Restart

Also, please attach the screenshot for Event Log, if above steps doesn't work for you.

Answer 3

The Run tool window displays output generated by your application. If you are running multiple applications, each one is displayed in a tab named after the run/debug configuration applied.

It highlight when any application in your IDE is in running state.
