Since upgrading to Android Studio 2.0 (stable) I\'ve noticed an issue that wasn\'t there in the previous version of Android Studio 1.5 I had installed.
I\'m working
Check image for reference Turn off Instant Run in Settings. File>Settings>Build,Deployment>Instant Run Deselect all options shown there.
Now white screen problem is solved.
In android studio 2.0,My APK size was 16 MB while using Instant Run Without using Instant Run it became 27 MB. While in 1.5 .. the size was 27 MB.
Instant Run is the culprit.
