android studio INSTALL_FAILED_UPDATE_INCOMPATIBLE

Question

I published a version of my app to market.
My project somehow corrupted.
I started a new project with the same package-name and same key-store
But when i run the project gives me this error: INSTALL_FAILED_UPDATE_INCOMPATIBLE

I think the new APK is generated with different Signature than the published one.

How can i generate APK with the same Signature with the published one?!
Thanks.

Do you already have that app installed on the device on you are trying to run..

This may help:

1. Uninstall App adb uninstall package-name

2. Reboot Device (if problem still exists)

   there may be signature difference between the app that is installed on your device and the app you are trying to install.
