When I start app (First launch or Launching after killing it through task stack), It takes around 5-6 seconds to come to Launcher screen and shows white screen.

When I made launcher activity translucent then still same app lag time is there.

One more thing is that if I play with application for some time like 30 min and kill it through task stack then it take much more time like 15-20 seconds to launch.

I have read all blogs and answers on stack-over flow but it did not help.

Some information regarding above scenario:

  1. When app takes more than 10 seconds then I observed that it does verification of objects as it show in logs.
  2. I have instance and variable in Application class to use it throughout app.
  3. I have GCM also in app.

  • You are probably making too much thing during onCreate and this way, your Activity is taking time to prepare the screen... Is it impossible to help without any code... – guipivoto Jul 26 '16 at 12:11
  • If it is blocker for a release you could show a splash screen as a quick fix. But the main issue lies in the activity. Probably you are doing too much in home screen. You layouts are too complex too be rendered in lesser time. – Arpit Ratan Jul 26 '16 at 12:13
  • post your code,may be you are doing lots of task in the oncreate or main thread.or check GCM token getting implemented properly. – Jithu P.S Jul 26 '16 at 12:13

Thanks for the suggestions. It worked for me by disabling Instant Run. I checked on this link Android Studio 2.0 - pause/white screen on App first run
