I don't know if this is the right place to ask this question I have no one else to turn to for help ... My android studio was working fine a couple of days back and run configuration was also ok but now i am having issue with it ... I am getting a cross ( x ) sign over the android icon please have a look at the images below
A cross on the little android icon
Change the build variant from the bottom left panel to
debug and you should be able to run it fine from Android studio. It will use the default debug signing configuration in this case.
You cannot run a
release build variant directly unless you specify the signing config explicitly under
bulidTypes - > release
