I had a similar problem when updated my android studio. Somehow it changed my SDK path. I just changed it to my updated SDK path and it worked.

Android Studio -> File -> Settings -> Appearance & Behaviour -> System Settings -> Android SDK

Here you will find Android SDK location just click on edit link in front of that and browse and select the Android SDK from the file browser. Select and click on Apply.

Select AVD manager and start Emulator. This solution worked for me.

I too had the same problem, then I went to AVD manager and right click on the emulator and stopped it and I RUN the application again and this time it worked. it may be a temporary solution but works for the time being.

AVD manager-> right-click on the emulator you are using -> Stop

Now Run your application again.

Note: Sometimes closing the emulator directly is not working for the above-mentioned problem but stopping it from the AVD manager as mentioned is working.
