Android Studio App Apk Installation Error

Question

I get this following error every time i try to run my app, wasn't happening couple days ago and i have never seen this before. I am running android studio 4.0

Stuff i tried

• File -> Invalidate Caches / Restart
• Build -> Build bundle(s) / APK(s) -> Build APK(s)

Answer 1

Build Gradel Again (on image mark 1), Then Run the App on Device/Emulator (on image mark 3). If it also don't work restart your android studio and run again.

Hope it would solve the issue!
