java - Android Studio 'Run app' dialogue doesn't appear in one project but will in another -
i'm toying android studio making simple stupid app learn saving key preferences , ran weird obstacle. i'll try provide as can since may hard reproduce bug both apps i'm running super basic , there no compile errors.
specs: no emulator, i'm running samsung galaxy tablet. windows 7, android studio 1.2, gradle 2.2.1.
in question title, mean have project named kitty (pretty hello world , button). click run->'run app'->(dialogue box opens)->ok->within moments app launches on tablet.
^^^this beautiful screen want see on sharedpreferences, it's on kitty.
now started project called sharedpreferences (gist: 2 checkboxes ask "do chocolate" , "do luigi" , check 1 none or both , press save. 2 textviews underneath update if things , later if reopen app textviews remember chocolate luigi preferences). main_activity.
i don't think changed settings or project preferences between 2 , neither give me error. mainactivity.java outdated original see edit:
