Unable to open run window in android studio

Question

trying to open the run window (with click on button or shift+F10 ) but not getting any response.

Answer 1

I assume you are saying you are not getting devices in the list. And with this assumption, I would say it's due to adb issues.

Try killing and restarting adb:

1. adb kill-server
2. adb start-server

Above command will kill the adb services and then start it again.

Answer 2

Android Studio makes a lot of files as caches and does not delete them. This can cause trouble when there is a need to make new files, so clearing caches will clear the old cache and make Android Studio faster. Go to File --> and click invalidate catches/restart
