I am using Windows with current AndroidStudio version is 2.1.1.
Sometime I run my app by Run app button (Shift+F10) my app won't start.
When it's happened, I always use Build -> Rebuild Project then Run app and my app will start normally
However, now my project bigger and my computer performance is not good so Rebuild Project take too much time (about 1-2 minutes)

Can I run my app again without Rebuild Project? And why my app sometime won't start?
Any help or suggestion would be great appreciated.

  • You really need to rebuild so that it will regenerate a new test apk. – Enzokie May 31 '16 at 00:59
  • You may try regenerating your R.java and try unchecking "Use external build" in compiler settings as suggested here: http://stackoverflow.com/questions/17269421/android-studio-need-to-rebuild-project-before-each-run – mgcaguioa May 31 '16 at 01:17

How about use this button: Rerun. This will build your project again without clean task, it should be fast.
