Android Studio - install apk failure

Question

I've tried to build .apk, so I have chosen Gradle tab from the right side, select my app, then ":app" and then "assemble"->Run. Now i have app-release-unsigned.apk file, but when I try to install it I get message "App is not installed". What can I do, to make it works?
