I updated to Android Studio 3.1 along with other library updates like support-repository, HAXM, LLDB etc.
After update, when I tap run button(green-triangle), the Android Studio instantly runs app without building. Any changes I made are not affected in the installed app. As soon as I tap run, It says:
> Installing app
> Launching activity
This happens in under 2 seconds. What could be wrong?
If I rebuild project, and then run the app. Same happens, but my changes appear in app.
When Android Studio was updating, I chose to import settings from Android Studio 3.0 as well.
