I have an application which was working fine with gradle 1.5.0. Application use to launch instantly after gradle build.
But when I changed the gradle to gradle 2.1.0 it launches with a delay of 5-6 seconds for first time after gradle build. I have tested with some of my other apps also in those apps also same issue persists.
Then I changed the gradle version back to gradle 1.5.0 then again my app started working fine without any delay.
So, it seems like there is an issue with gradle 2.1.0.
Moreover, I noticed one more thing that when I run the app with gradle 2.1.0 then the cache memory of app shows around 11-12 MB after first time launch without performing registration or any other action in app
While on running with gradle 1.5.0 cache memory size remains around 15-17KB.
