i uninstalled app in phone but i try to run my project using android studio

Issue

enter image description here

I deleted the app which I created but I deleted it on my phone and I tried running it again but it is showing error type 3. it is running in other phones but not on the photo I deleted.

Solution

I faced a similar problem after refactoring. This is what i did to resolve this issue:

Cleaned the Project Deleted the Build directory Restarted Android Studio Rebuild the Project Run Optionally (Go to the files menu on android, click on "Invalidate Caches / Restart..." uninstall the app on your phone and try again)

see : Error type 3 Error: Activity class {} does not exist
