Application Installation Failed in Android Studio

Again in this issue also I found Instant Run buggy. When I disable the Instant run and run the app again App starts successfully installing in the Device without showing any error Window. I hope google will sort out these Issues with Instant run soon.

Steps to disable Instant Run from Android Studio:

File > Settings > Build,Execution,Deployment > Instant Run > Un-check (Enable Instant Run to hot swap code)

If you use MIUI ROM

Go to the developer option and in that disable MIUI optimization.You will be asked to reboot your phone. Reboot it and then run the app.

Your APK file is missing . So , Clean Project >> Build APK >> Run the project .
